42 Topic 3 Final Project Basic Parts of the Mountain Board TOPIC 3 FINAL PROJECT - BASIC PARTS OF THE MOUNTAIN BOARD Objective When you have completed this topic, you will have the knowledge and experience to design basic parts of a mountain board. Using SolidWorks you will create the binding anchor, binding, wheel hub, and the deck. You will determine the design intent for each part being created. You will also complete an initial analysis of your design using SimulationXpress. Overview Designers create, plan, and develop the products and environments we use and experience in our everyday lives. Design is everywhere. Whatever we wear, sit on, live in, drive, and work with - including our tools, vehicles, toys, furniture, home or commercial environments - a designer has had a hand in its creation and development. There is an ongoing demand for new design. In the next three topics you will be designing and analyzing a mountain board, which is comprised of the deck, truck, axle assembly, wheels, and the bindings. Individual parts will be created and then assembled into several subassemblies until the finished mountain board is complete. In this topic, you will begin the design process by completing the basic parts, the revolved features, and the thin features of the mountain board. 36

54 Topic 3 Final Project Basic Parts of the Mountain Board Activity Directions: Creating the Binding Base Plate Before you begin the steps to create the binding base plate you need to know the design intent for this part. Go to your Student Guide/Portfolio, Data Sheet- Design Intent: Binding Base Plate, in Topic 3, Activity 1. SolidWorks should be on your screen. If it is not, click on the Application Launch button and choose SolidWorks from the menu. Follow the directions below to complete the activity. The binding anchor you just created was created by adding material on top of material to get the basic geometry. For the binding base plate, the approach will be to create an oversized block of material and use a cookie cutter to cut away the material around the final part. 1. Click File and then Open on the Standard toolbar. The Open dialog box appears. Navigate to the C:\Mountain Board folder in the Look in: box. In the Files of type: box, click on the down arrow and select All Files. Doubleclick on the Part_MM your last name.prtdot file. 2. In the FeatureManager design tree, select the Top plane. Save the new part before going any further. Click File and then Save As. Save the part in the C:\Mountain Board folder as Binding Base Plate your last name. Select Part from the Save as type: drop-down list. Click Save. The.sldprt extension is automatically added to the filename. 3. Click Sketch on the Sketch toolbar. Click on the Top plane. 4. Click View, Sketch Relations, if it is not already selected. From the origin, create a vertical and horizontal line as shown. The vertical line should be about 200 mm and the horizontal line 75 mm. 48

55 Topic 3 Final Project Basic Parts of the Mountain Board 5. Create another horizontal line from the end of the vertical line. Make this line about 35 mm. 6. Create a line from the end of the first horizontal line. Make sure that this line is NOT vertical. 7. Click Tangent Arc on the Sketch toolbar. Draw an arc from the endpoint of the angled line to the end of the top horizontal line. 49

56 Topic 3 Final Project Basic Parts of the Mountain Board Check the relationships of the arc. There was a tangent relationship added between the arc and the line where the arc started. 8. Notice that there is no tangent relationship between the arc and the top horizontal line. The automatic tangent relationship is only added to the starting end of the arc. To test this, drag the left end of the upper horizontal line to the left. If a tangent relationship is required at the finish end, it must be added manually. 50

57 Topic 3 Final Project Basic Parts of the Mountain Board 9. Click on the Sketch toolbar. Select the arc and the upper horizontal line. 10. Click Tangent. Click OK. The arc and upper horizontal line are now tangent. 11. Fully define the sketch by adding the dimensions shown. All the sketch geometry should now be black. 51

58 Topic 3 Final Project Basic Parts of the Mountain Board 12. Extrude the feature by clicking Extruded Boss/Base on the Features toolbar. 13. Create a Blind extrusion to a depth of 25 mm. Click OK. To get the shape you are interested in, you need to use an Extruded Cut to remove the unwanted material from your base feature. 14. Select the face shown and open a new sketch. 15. Click on the Standard Views toolbar to change the view so that you are looking normal to the sketch plane Select the Line tool. 52

59 Topic 3 Final Project Basic Parts of the Mountain Board 17. Position the cursor over the lower edge of the part. 18. When you are over the edge, the cursor feedback will be. This is the feedback for coincident, meaning you are on the edge. Sketch a line to the right. 19. Add a Tangent Arc. Draw a tangent arc from the right endpoint of the line to the midpoint of the right vertical edge. The midpoint is displayed with a square with two diagonal lines. Once the arc is drawn there will be a midpoint relationship established with the right vertical line. 20. Add a Tangent Arc from the left end of the line to the midpoint of the left vertical edge. 21. Dimension the sketch as shown. Save your work. Offset Sketch Entities The Offset Entities tool is used to make a copy of sketch entities, or edges, offset from the original by some specified distance. 22. Click any of the three sketch entities (line, left tangent arc, or right tangent arc). 23. Click Offset Entities on the Sketch toolbar. Select Chain will be selected by default; this will select all sketch entities that are continuously connected to the one you selected. 24. Enter 3 mm for the offset. Select Reverse, if necessary, to make the preview appear above the other sketch entities. Click OK. Each arc and the line are duplicated at an offset distance of 3 mm. 53

60 Topic 3 Final Project Basic Parts of the Mountain Board 25. The sketch must be closed to extrude the cut. You will add two lines to connect the ends of the arcs. These lines need to be perpendicular to the arcs. This means that the lines must point through the centers of their respective arcs. 26. Draw a line to connect the ends of the two arcs on the left. The line should become fully defined (black). If the line does not become fully defined, you need to add a relationship to make the line perpendicular to the arc. Because you cannot add a perpendicular relationship between the arc itself and the line, you will add a coincident relationship between the line and the center point of the arc. By basic geometry this will make the line perpendicular to the arc. Click Add Relation on the Sketch toolbar. Whenever the PropertyManager or a dialog box has an entry box colored in the salmon color, anything selected in the graphics area will be entered in the box. Select the arc center point and the line. Click to add a Coincident relationship. The line will now be black as it is fully defined. 27. Repeat the procedure to close the sketch between the arcs on the right. Cut to the Outside The Extruded Cut command can either cut what is enclosed by the sketch or everything outside the sketch. 28. Click Extruded Cut on the Features toolbar. 54

61 Topic 3 Final Project Basic Parts of the Mountain Board 29. Select Through All for the end condition. By default, the cut will remove the material inside the sketch. 30. Select Flip side to cut. Now the cut will keep the material that is inside the sketch and remove the material that is outside the sketch. 31. Click OK. Change to view to Isometric. Save and Print the part. 55

62 Topic 3 Final Project Basic Parts of the Mountain Board Creating the Side Tabs The two side tabs provide the mounting locations for the binding straps that go over the rider s foot. They must be offset from the base plate to allow for the thickness of the strap. They must also be a uniform thickness as the final product will be cut from flat material and bent into the final shape. 1. Select the face shown and open a sketch. 2. Change the view orientation to Normal To by clicking on the Standard Views toolbar. 3. Select the Rectangle tool from the Sketch toolbar. 4. Start the rectangle with a coincident relationship to the bottom edge of the binding base plate. Drag the rectangle until you get a coincident relationship with the top edge. 56

63 Topic 3 Final Project Basic Parts of the Mountain Board The two coincident relationships control the height and vertical position of the rectangle. To make it fully defined, only a width dimension and a single positioning dimension are need. 5. Add the two dimensions shown. 6. Select Extruded Boss/Base and extrude the sketch to a Blind depth of 4mm. Create the tab 7. Create a new sketch on the new face created by the offset. 57

64 Topic 3 Final Project Basic Parts of the Mountain Board 8. Sketch a rectangle. Start the rectangle at the lower left corner of the offset. The cursor feedback will show the yellow coincident callout to indicate you are on the endpoint of the edge. 9. Add a relationship. Click Add Relation on the Sketch toolbar. Select the right vertical line of the sketch and the right vertical edge of the offset. 10. Click Collinear and click OK. The rectangle will now stay the same width as the offset. 11. Dimension the height of the rectangle to 32 mm. 12. Extrude the sketch, Blind to a depth of 3 mm. Binding Attachments The binding straps will attach to the base plate through two curved slots. The slots need to be curved to allow the binding straps to rotate as the foot is pushed into the binding. 58

65 Topic 3 Final Project Basic Parts of the Mountain Board 13. Select the outside face of the tab and open a sketch. With the outside face of the tab still selected, click. 14. Click Zoom to Selection on the View toolbar. This will make the selected entity fill the graphics area. The two slots are symmetrical. To create them, you will sketch one and mirror it get the second. 15. Create a centerline. Start the centerline at the midpoint of the top edge and make sure it is vertical. 16. To mirror as you sketch, click Tools, Sketch Tool, Dynamic Mirror, and then click on the centerline. 59

66 Topic 3 Final Project Basic Parts of the Mountain Board Drawing the Centerpoint Arc is a two step process. You first drag from the center of the arc to the start point of the arc. Release the mouse button, then press and drag the length of the arc. 17. Select the Centerpoint Arc from the Sketch toolbar. 18. Start the arc from the centerline and drag the radius/start point as shown. Release the mouse button. This will be the point where the arc begins. 19. Click the mouse button and drag until the arc is as shown, then release the mouse button. 60

67 Topic 3 Final Project Basic Parts of the Mountain Board 20. Draw another Centerpoint Arc using the same centerpoint. This makes the arcs concentric. 21. Draw Tangent Arcs to close up the sketch. Add Tangent relationships to make sure all the arcs are tangent to the arcs they are connected to. 22. Turn off Dynamic Mirror. 23. Add the Dimensions shown. 24. To create the 6 mm dimension between the arcs, pick the arcs on each end of the slot. As you drag the cursor, the dimension preview will show: 61

68 Topic 3 Final Project Basic Parts of the Mountain Board 25. To lock in the type of dimension you want, click the right mouse button to set it. That type of dimension will stay active no matter where you then move the cursor. 26. Next Extrude a cut. Select Up To Next. Click OK. 27. You will now create another tab on the other side of the Binding Base Plate. Create the offset feature on the face shown. 28. Position the offset 70 mm from the vertex shown. This part will be manufactured from a flat piece of metal. It will first be cut to shape, and then the tabs will be bent, followed by the front a back curves. Because the part will be manufactured from a single piece of metal, the model must have a uniform thickness. You will add the bends manually using fillets. 62

69 Topic 3 Final Project Basic Parts of the Mountain Board 29. You must add a fillet to the inside edge of the tab at the correct radius to keep the material uniform. To calculate the fillet radius: The radius of the inside fillet = radius outside fillet - material 30. Apply a 1 mm fillet to the inside edge. The finished bend now has a uniform thickness. Add bends 31. Select the top flat face of the Binding Base Plate. This will be the face that will be fixed. All the bends will move relative to this face. 32. Click Insert, Sheet Metal, Bends from the menu. 63

70 Topic 3 Final Project Basic Parts of the Mountain Board 33. Set the bend radius. Change the Bend Radius to 3 mm, which is the material thickness. Leave the remaining option as shown. Click OK. 34. Three new features are added to the FeatureManager design tree. Sheet-Metal1 contains the sheet metal definitions such as the bend radius we entered in the last step. Flatten-Bends1 creates a flat pattern or the part. Process-Bends1 contains the information to bend the flat pattern into the final part. Rollback The model can be rolled back to a previous state by moving the rollback bar at the end of the FeatureManager design tree. To rollback the FeatureManager design tree, move the cursor over the rollback bar (the line that is normally at the bottom of the FeatureManager design tree). The cursor will change to a hand, then drag the rollback bar to the desired position. 35. In the FeatureManager design tree, move the cursor over the rollback bar and drag the rollback bar to a position between Flatten-Bends1 and Process-Bends The part will flatten. 64

71 Topic 3 Final Project Basic Parts of the Mountain Board Add Fillets The sharp corners need to be rounded to make the part look better and for safety reasons. 37. Add 15 mm fillets to the corners shown. 38. Add 6 mm fillets to the corners of the tabs as shown. 39. Add 2 mm fillets to the corners shown. 40. Bend the part by moving the rollback bar to the end of the FeatureManager design tree. The part will bend to its final shape. 65

72 Topic 3 Final Project Basic Parts of the Mountain Board Center Hole To hold the Binding Base Plate to the deck, you will have to create a hole. This hole will also fit the Binding Anchor you previously created to the deck. 41. Rollback the part to before Process-Bends1. *Note: Rollback can also be done through the right mouse button menus. Right-click on Process-Bends1 and select Rollback. 42. Create a sketch on the top face of the part. Sketch a circle and dimension it as shown. *Note: You want to cut the hole just slightly larger than the size of the boss on the Binding Anchor part. You want the fit tight, but not so tight that it is hard to assemble. 66

73 Topic 3 Final Project Basic Parts of the Mountain Board 43. Extrude a cut. You ll notice a new end condition appears called Link To Thickness. This is because the part has been turned into sheet metal by the Insert Bends command. This makes the cut depth the same as the material, even if the material thickness changes. 44. Bend the part. Right-click the feature Process-Bends1 and select Roll To End. Because you are concerned with the overall weight of the product, material should be attached to each part as you build them, this will make it easier to check the weight of the entire product as you assemble it. 45. Attach the material Aluminum 2014 to the part. Either click Edit Material on the Standard toolbar or select Edit, Appearance, Material from the menu. 46. In the Materials Editor, expand the Aluminum Alloys category by clicking the plus sign. Select 2014 Alloy and click OK. 47. Save and Print the part. Complete the Activity Directions: Creating the Binding Assembly. 67

74 Topic 3 Final Project Basic Parts of the Mountain Board Activity Directions: Creating the Binding Assembly You will now create an assembly of the two parts of the binding that you made. 1. To create a new assembly, click Make Assembly from Part/Assembly on the Standard toolbar. 2. Select the template Assembly and click OK. Because you selected to make an assembly, only assembly templates are shown. Insert Component is automatically activated by SolidWorks when you open a new assembly. This is done just to save time. You only have one file open, so it is automatically selected and a preview of the part is attached to our cursor. The part will move with the cursor. If the part was not open, you could select the Browse button to locate it. *Note: If you do not see the preview graphic when your cursor is in the graphics area, select Graphics preview in the PropertyManager. 3. Place the part by moving the cursor to the assembly Origin. When the cursor is over the Origin, it will change to the part.. Click on the Origin to place You may remember from Level 1, that the initial component added to the assembly is fixed. Fixed components cannot be moved and are locked into place wherever they fall when you insert them into the assembly. By using the cursor during placement, the component s origin is at the assembly origin position. This also means that the reference planes of the component match the planes of the assembly, and the component is fully defined. There are six degrees of freedom for any component that is added to the assembly before it is mated or fixed: translation along the X, Y, and Z axes and rotation around those same axes. How a component is able to move in the assembly is determined by its degrees of freedom. The Fix and Insert Mate options are used to remove degrees of freedom. 68

75 Topic 3 Final Project Basic Parts of the Mountain Board 4. Open your part Binding Anchor part. You saved this part in the C:\Mountain Board folder as Binding Anchor your last name. 5. Tile the windows by clicking Window, Tile Vertically from the menu. Close the part window of the plate part - keep the assembly1 window and the binding anchor window open (see below). 6. Drag the top level icon from the FeatureManager design tree of the Binding Anchor into the graphics area of the assembly. 7. The Binding Anchor is now added to the assembly. 8. The Binding Base Plate is fixed, but the Binding Anchor still has all six degrees of freedom. Maximize the assembly window by clicking Maximize on the Assembly window title bar. Select Zoom to Fit. One or more selected components can be moved or rotated to reposition them for mating using the mouse or the Move Component and Rotate Component commands. Also, moving under defined components simulates movement of a mechanism through dynamic assembly motion. Mate the Binding Anchor The Binding Anchor holds the Binding Base Plate to the deck of the mountain board. It will require two mates to position it correctly. A Concentric mate will hold the Binding Anchor in the center of the hole in the Binding Base Plate. The second mate will position the top face of the Binding Base Plate coincident to the underside of the lip of the Binding Anchor. 69

76 Topic 3 Final Project Basic Parts of the Mountain Board 9. Move the Binding Anchor to a position near the Binding Base Plate by selecting the Binding Anchor, then holding down the left mouse button and dragging the Binding Anchor to the desired position. 10.

Exit the sketch by clicking Exit Sketch for the Sketch toolbar. 79

86 Topic 3 Final Project Basic Parts of the Mountain Board Add the Bolt Hole The hole in the spoke needs to be multi-functional. Because two hubs will be positioned back to back, the hole must have a hexagonal cutout to capture the nut as well as be sized so that the bolt head can turn to be tightened. You will first create a clearance hole for the bolt shaft, then the hexagonal cut. The Hole Wizard is used to create specialized holes in a solid. It can create simple, tapered, counterbored, and countersunk holes using a step by step procedure. 1. Select the face of the spoke. 2. Click Insert, Features, Hole, Wizard from the menu. This starts the Hole Wizard. 3. Click the Hole button. Using the pull-down lists, select: Standard: Ansi Metric Screw type: Screw Clearances Size: M6 End Condition: Through All 4. Click on the Positions tab. You can now edit the sketch that determines the hole position(s). The message tells you to locate the hole center(s). 5. Turn off the Point tool by clicking it once on the Sketch toolbar. The sketch entity Point is automatically turned on so that you can place several holes. You are only placing one hole so you can turn off the tool. 6. Position the hole. Click to add a relationship. Select the Point, Construction Line, and Construction Circle.

The selected face will now fill the screen. 10. Select the Polygon tool from the Sketch toolbar, or select Tools, Sketch Entities, Polygon from the Main menu. Sketch a Polygon by selecting the center point and dragging to some radius. The size and position are not important as we will set those in the following steps. 11. Add a Concentric relationship between the new construction circle located inside the hex and the circular edge of the hole. 81

88 Topic 3 Final Project Basic Parts of the Mountain Board 12. Dimension the new construction circle to 10.5 mm. Why dimension the construction circle? Part of the design intent is that this hex cut captures the nut, but also that the bolt head must be able to rotate inside the cut. The dimension represents the size of a clearance hole for the bolt head. You could have also dimensioned the hex hole from flat to flat, but it doesn t represent the design intent as clearly as dimensioning the circle diameter. 13. Add a Horizontal relationship to one of the lines of the hexagon. This is necessary to fully define the sketch. Without this relationship, the sketch is free to rotate about its center. Click OK. 14. Create an Extrude Cut to a depth of 6.5 mm. Select Surface/Face/Plane in the from drop down box. Click on the Hex surface. Click OK. 15. Right-click on the centerline and select Hole. Do the same for the construction circle. 16. Rename this feature Hex-Cut. 82

Click on the three angled lines shown and select Parallel. Then click on the two angled lines shown and select Equal. Click OK. 8. Revolve the rim. Click Revolved Boss/Base on the Features toolbar. 86

93 Topic 3 Final Project Basic Parts of the Mountain Board 9. Revolve One-Direction, 360 degrees. Click OK. 10. Rename this feature Rim. Pattern the Spokes The Wheel Hub will have three spokes. You have created one and will create the other two as a pattern of the first. By creating the spokes as a pattern, you can quickly change the number of spokes as well as their design. Circular Patterns Circular Patterns create copies, or instances, in a circular pattern controlled by a center of rotation, an angle, and the number of copies. The instances are dependent on the originals. Changes in the originals are passed on to the instanced features. Axes SolidWorks has two types of axes: Temporary Axe: These are created by SolidWorks any time a cylindrical or conical solid is created. Axes: These are created manually by the user. 1. View the temporary axes. Click View, Temporary Axes. This will be the axis that will be used to pattern the spokes. 2. Create a circular pattern. Click Circular Pattern on the Features toolbar. 3. Select the Temporary Axis in the graphics area. 87

94 Topic 3 Final Project Basic Parts of the Mountain Board 4. Click the Features to Pattern box to make it active. 5. Click the Circular Pattern title at the top of the PropertyManager to fly-out the FeatureManager design tree. 6. Select Spoke, M6 Clearance Hole1, Hex-Cut and Hex- Cut Chamfer. These are all the features we want to pattern. 7. For the number of instances either type 3 or use the arrows to change the number to Make sure Equal spacing is selected and the angle is set to 360 degrees. 9. Click the Bodies to Pattern box to make it active. Click on the front surface of the hub. (Go to the Front View.) 10. Click OK. The spoke, along with the two holes and the chamfer have been patterned. Add Fillets Fillets need to be added to the spokes to round all the edges. Rather than add the fillets to all three spokes individually, you will just add the fillets to the first spoke, then include the fillets into the pattern. 1. In the FeatureManager design tree, select the feature named Spoke. By selecting a feature in the FeatureManager design tree, the feature will be highlighted in the graphics area. 88

95 Topic 3 Final Project Basic Parts of the Mountain Board 2. Add a 4 mm fillet to both sides of the spoke where it contacts the hub. 3. Rename this feature Fillet R4. 4. Add a 2 mm fillet to the three edges shown. 5. Rename this feature Fillet R2. 6. Right-click the feature CirPattern1 in the FeatureManager design tree and select Edit Feature. 89

96 Topic 3 Final Project Basic Parts of the Mountain Board You want to add the two fillets into the definition of the circular pattern; however they are grayed out and cannot be select. They cannot be selected because they were created later in time than the circular pattern, so when the circular pattern was created, the fillets did not exist. 7. Exit the circular pattern by clicking Cancel. Features can be reordered in the FeatureManager design tree by simply dragging and dropping the feature in a new location. When dragging a feature, the cursor will change to indicating that the new location will be under the feature highlighted. If you drag the feature too far up the FeatureManager design tree, the cursor will change to, indicating that you cannot drop the feature at this location. The parents and children of any feature determine its relationships. Parents are used to create the new feature; the new feature is then dependent on the parent. For the child feature to exist, the parent feature must exist. 8. In the FeatureManager design tree, right-click Fillet R4 and select Parent/Child from the menu. 9. The fillet has two parents, the Spoke and the Hub. This is logical as the fillet connects the two features. The fillet has no children, in other words, no features depend on the fillet. Select Close. 90

97 Topic 3 Final Project Basic Parts of the Mountain Board 10. Reorder the features. Drag the feature Fillet R4 to a position between the Rim and the CirPattern Drag the feature Fillet R2 to a position after Fillet R In the FeatureManager design tree, right-click CirPattern1 and select Edit Feature. 13. Select Fillet R4 and Fillet R2 and add them to the Features to Pattern. 14. Click OK. The fillets have now been added to the circular pattern and appear on all the spokes. Add Additional Fillets Because the spokes were patterned before the rim was created, fillets between the two cannot be added to the pattern. You can add all the fillets to the three spokes individually, but this is a lot of work. You might try to fillet one spoke and pattern the fillets, however this doesn t work. Fillets need to be patterned with the underlying geometry. To allow the fillets to be added to the pattern, you must roll back the model to before the circular pattern. 91

98 Topic 3 Final Project Basic Parts of the Mountain Board 1. In the FeatureManager design tree, right-click CirPattern1 and select Rollback from the menu. 2. Click Insert, Features, Fillet/Round from the menu. 3. Add additional fillets to round remaining sharp edges. Add a 3 mm fillet. Select the face and edges shown.

Finish the front by adding a 0.5 mm by 45 degree chamfer to edge of the hole where the bearing will be inserted. Click OK. 92

99 Topic 3 Final Project Basic Parts of the Mountain Board 6. Roll the model forward to the end. Right-click in the FeatureManager design tree and select Roll to End. Add Index Pins and Index Holes Index pins and holes provide two functions; first they help to line up the parts as they are put together in the assembly process. Second, they prevent the two halves from rotating, relative to one another, when they are in use. 1. Change to the Back view by clicking Back on the Standard Views toolbar. Change to Shaded with Edges. 2. Create a sketch on the back face of the model by clicking on the face. 3. Sketch a circle with its center on the Origin. Dimension the circle to 77 mm. The pins and holes will be placed on this circle. You do not want this circle to create an extrusion or cut, you just want to use it to line up other sketch entities. 93

100 Topic 3 Final Project Basic Parts of the Mountain Board 4. In the PropertyManager for the circle, select For Construction. The circle now changes to a construction line. 5. Create two construction lines. The end points of each line must be coincident with the construction circle and each line must be horizontal. 6. Add angular dimensions. To fully define the construction geometry, add the angle dimensions show. Select the Smart Dimension tool, and then select the Origin and each end of a line. Drag the dimension to the position shown. Repeat for the other dimension. 94

101 Topic 3 Final Project Basic Parts of the Mountain Board The four endpoints will be the locations for the pins and holes. 7. Sketch a circle at the endpoint of each line. 8. Dimension the two top holes. Dimension the circle on the right 3.9 mm and the circle on the left 3.8 mm. The larger circle will be used to create the hole and the smaller circle the pin. The difference in dimensions allows for a slight clearance to make sure the pins don t stick. 9. Add an Equal relationship between the two circles on the right. Repeat with the two circles on the left. This will make the two holes the same size and the two pins the same size. The sketch is now fully defined. 10. Click Extruded Boss/Base to create an extrusion. 11. Set Direction 1 to Blind and the depth to 4.5 mm. Rotate the model to allow you to see the preview. Do not click OK yet. 95

Click the plus sign next to Index Pins and Index Holes to show the sketch underneath. Notice that both features use the same sketch and that the sketch icons show the hand which indicates sharing. You will now add a Chamfer to the top of the Index Pins because you do not want to leave sharp edges on a small feature. 22. Click Chamfer then select the edges of the two pins. Select Distance distance for the type of chamfer and set the two distances to 1.5 mm and 1.0 mm. 23. Click OK. 24. Save and Print the Wheel Hub. Hole for Tube Stem The tire that will be used has a tube. There must be a cutout in the hub for the tube stem so that the tube can be inflated. You will create a revolve cut opposite one of the spokes. 1. Change to the Back view by clicking Back on the Standard Views toolbar. 2. Create a sketch on the back face of the model, by clicking on the face. 97

104 Topic 3 Final Project Basic Parts of the Mountain Board 3. Sketch a vertical centerline from the Origin. 4. Sketch a rectangle roughly in the position shown. 5. Add two Coincident relationships as shown. This will insure that we cut all the material in the rim. 6. Add a Collinear relationship between the left side of the rectangle and the centerline. 7. Dimension the width of the rectangle to 5.8 mm. 8. Create a revolved cut by clicking Revolve Cut on the Features toolbar. The cut can revolve 360 degrees even if it is only cutting material for 180 degrees. 9. Add a 0.5 mm by 45 degree chamfer to the edges of the cut as shown. 10. Save, Print, and Close the wheel hub. 98

105 Topic 3 Final Project Basic Parts of the Mountain Board Activity Directions: Importing Data For the mountain board, you are not going to design and manufacture the tire and the tube; you are going to use a supplier that makes both of these items. To include the tire and tube in your assembly, you need a CAD model. The supplier uses a CAD system that saves files in a format not supported by SolidWorks direct translators. To get the CAD model, the supplier has provided them in two neutral formats. 1. Click File, Open from the menu. 2. Select IGES (*.igs, *iges) from the Files of type list. 3. Examine the list to see the other files types that can be opened in SolidWorks. 4. Select the file Tire.igs from C:\Mountain Board Parts Library folder. 5. Click the Options button. You can change the settings for the import process. Set the options to: Surface/solid entities o Try forming solid(s) Perform full entity check and repair errors Automatically run import diagnostics 6. Click OK then Open.

120 Topic 4 Final Project Multibody Parts of the Mountain Board TOPIC 4 FINAL PROJECT - MULTIBODY PARTS OF THE MOUNTAIN BOARD Objective When you have completed this topic, you will have the knowledge and experience to design multibody solids. You will explore the three Boolean operations that can be used to combine multibody solids within SolidWorks by evaluating the design of the mountain board s axle. You will create several of the features of the mountain board s truck by creating individual solid bodies, then combining them into the final shapes. You will also create the spring and the binding straps for the mountain board. Overview Multibody solids occur when there is more than one solid body in a part. Multibody solids are created in several ways. You will explore commands in SolidWorks that have the option of creating multiple solid bodies from a single feature. Using multibody techniques, you will create parts and features. You will first create extrusions based on the standard views of the final part, and then you will combine them into a single body. 114

121 Topic 4 Final Project Multibody Parts of the Mountain Board Activity 1 Creating the Axle and Truck Objective When you have completed this activity, you will have the knowledge and skills to explore how the axle was designed and create the truck for the mountain board. You will be able to: evaluate the design intent for the axle and the truck. explore the combined bodies technique in SolidWorks. use multibody techniques to create the truck. use extrusions and revolves to create features for parts. Activity Directions: Creating the Axle Click on the Application Launch button and choose SolidWorks from the menu. Follow the directions below to complete the activity. The Axle was created for you. You will evaluate the features of the Axle by exploring how the model was designed. You will see how two individual solid bodies were combined into the final shape. 1. Click File and then Open. The Open dialog box appears. Navigate to the C:\Mountain Board Parts Library folder in the Look in: box. In the Files of type: box, click on the down arrow and select Part. Double-click on the Axle file. 2. Click on File and then Save As. Save the part in the C:\Mountain Board folder as Axle your last name. Select Part in Save As type. This design started with the following sketch created on the Front plane and extruded to a depth of 11 mm. 115

122 Topic 4 Final Project Multibody Parts of the Mountain Board Then the following sketch was created on the Top plane with both arc being tangent to each other and to the lines they are attached to. The sketch was then extruded to a Blind depth of 46 mm. Examine the results of the two solid bodies. Because the results of the two extrusions were not merged, each remains separate. Look at the graphic. Notice that there is no edge where the two bodies intersect. 116

123 Topic 4 Final Project Multibody Parts of the Mountain Board The two solid bodies were combined using the Combine tool on the Features toolbar. The Common tool was used to create a single solid body from the volume that is common to the two bodies. There are four possible choices for combining the two solid bodies. 117

124 Topic 4 Final Project Multibody Parts of the Mountain Board The following sketch was then created on the Top plane and extruded to a depth of 11mm. The following sketch was created on the Front plane and extruded to a depth of 50mm. There are now three solid bodies. All the bodies were then combined to make a single solid. This was done in two steps. First, Extrude3 and Extrude4 were combined to get the common volume. Then the two combined volumes were added together. 118

125 Topic 4 Final Project Multibody Parts of the Mountain Board A rectangle was sketched, extruded, and a collinear relationship was added. A fillet was then created to the extruded rectangle and fillets were added to the edges. Full Round Fillets were added, edges were trimmed and filleted. 119

Select the helix near the end closest to the origin. Then click Sketch. 8. Sketch a circle. The position should be approximately as shown. You do not have to position it exactly; you will do that with a relationship. 154

161 Topic 4 Final Project Multibody Parts of the Mountain Board Pierce Relationships The Pierce relationship is used in sweeps. It can be thought of as a 3D Coincident relationship. In our spring, the circle will follow the helix. Think of the helix as a thin piece of wire and the profile sketch as being drawn on a piece of paper. If you stick the wire through the paper at the center of the circle, this would be a pierce relationship. 9. To add a Pierce relationship, select both the center of the circle and the helix by holding down the Ctrl key. There should only be one relationship shown, Pierce. Apply the Pierce relationship. 10. Dimension the circle to a diameter of 4 mm. The sketch should be fully defined. 11. Exit the sketch. When you create extruded or revolved features, only one sketch is involved, so you normally select Extrude or Revolve while you are still in the sketch. Because a sweep requires more than one sketch (profile and path) you must not be in Edit Sketch mode to start the sweep. 12. To create the sweep, click on the Features toolbar. Select the circle for the profile and the helix for the path. The callouts and color help to identify which sketch is which. 155

162 Topic 4 Final Project Multibody Parts of the Mountain Board 13. Set Options to Follow Path. This will keep the profile sketch normal to the path curve as it sweeps. Click OK. You now have the center section of the spring. You need to make some additions to create a realistic spring. Compression springs have the last turn at each end at a tighter pitch and the ends are ground flat to create more contact area. Create the Lower Helix 14. Select Sweep1 in the FeatureManager design tree and press Delete. You only want to delete the sweep feature, not the underlying sketches and helix. Make sure that Also delete absorbed features is cleared (not checked). Click Yes. 15. Delete the profile sketch (Sketch2). 16. Create another sketch on the Top plane. 17. Sketch a circle and dimension it to 25 mm. 18. Click Insert, Curve, Helix/Spiral. 19. Select Pitch and Revolution in Defined By:. Set the pitch to 4 mm and 1.0 revolutions. The Start angle must be 0.00 degrees to make the helix end where the original helix begins. 20. Select Reverse direction and Clockwise. Check the preview graphics to make sure the new helix is going in the correct direction. It should look like an extension to the original helix. Click OK. Create the Upper Helix 21. Click Insert, Reference Geometry, Plane. 22. Expand the Flyout FeatureManager design tree by clicking on the plus sign next to the part icon. Select the Top plane in the FeatureManager design tree and the top of the helix. 156

193 Topic 5 Final Project Final Assembly TOPIC 5 FINAL PROJECT FINAL ASSEMBLY Objective When you have completed this topic, you will have the skills and knowledge to successfully assemble all the parts you have created for your final project into the finished mountain board. You will also create an assembly drawing of the mountain board and present the results of your designs in a realistic manner. Overview Very few of the parts designed by engineers are used by themselves. Most become part of an assembly that may then become part of a larger assembly. This is true with the final project you designed. Of all the parts you created, most are part of a subassembly that will be part of a final assembly. Three of the sub-assemblies have already been created, the Wheel Assembly, the Spring Assembly, and the Binding. You will put together the remaining subassemblies, and then create the final assembly. The final assembly will start with the Deck as it forms the foundation of the Mountain board. The final assembly should be created in an order similar to the order that will be used to assembly the actual final product. During the product design process, there are numerous requirements for output of the design details. Engineers and designers must share information and work together to satisfy the design intent. Drawings are required for the manufacture of the product. Pictures are needed for brochures and web pages to market the product. Because of this, screen prints, photorealistic prints, drawings, and image files are a must during the design process and when presenting the final results of your project. In this topic, you will complete your mountain board and create realistic models of the parts and final project. 187
