3 General changes and CAD-commands Chapter 1. General changes and CAD-commands Improved language support The language support in IGEMS R9 has been improved in order to allow extended languages. USB-dongle IGEMS R9 will be delivered with new USB-dongles. The new dongle will no longer require installation of any software drivers. IGEMS R9 will however still support the old type of Safe Net dongle used in IGEMS R8 and older. Fillet The fillet command now works in two different ways. As before, with two mouse clicks. Image 1 It can now also work using only one single click. Image 2 The single click option is used if both endpoints are inside the pickbox rectangle. Object snap Grip The Grip option has been added to the object snap. Image 3 The Grip option snaps to insertion points of text and blocks. Page 3

4 General changes and CAD-commands Leader A leader command is a dimension command that can be used to add information to various objects. The command asks for text information. Image 4 When you press OK, the inserted text is placed on the drawing. Image 5 Improved AutoCAD DWG import The file format in AutoCAD 2010 is changed from Autodesk. Older versions of IGEMS will not be able to read newer AutoCAD files. The new DWG file format is supported in IGEMS R9. Paper space mode AutoCAD drawings can either be in Paper space or Model space mode when saved as a DWG file. Previous versions of IGEMS support only files made in Model space. IGEMS R9 has support for both modes. This will increase the possibility to use DWG files without special handling in AutoCAD. Page 4

5 Bonus 2010 Chapter 2. Bonus 2010 The Bonus package is always included when updating IGEMS from an older version. It is also free when buying a new license when annual maintenance is included at the purchase. The bonus package in 2010 includes the same features as the Bonus 2009 package but also a spur gear generator. Spur gear generator The spur gear generator is used to create evolvent gears with optional parameters. Image 6 This will show following dialog box. Image 7 General information on input parameters Module=Pitch diameter/teeth Pitch diameter=module*teeth Pressure angle is normally between degrees. AD=Addendum factor is normally set to DE=Dedendum factor is normally set to The input will generate CAD geometry as illustrated below. Image 8 Page 5

6 Changes in the 2D-CAM module Chapter 3. Changes in the 2D-CAM module Fine Abrasive waterjet (FAW) Abrasive waterjet cutting with extremely small nozzles for precision waterjet cutting needs other cutting values than normal AWJ cutting. These kinds of machines are supported in IGEMS_R9. Image 9 This machine type is a sub type to normal waterjet cutting. Image 10 The main difference is that these machines uses other kind of abrasive and has other sizes of nozzles and orifices. Image 11 Page 6

7 Changes in the 2D-CAM module The Orifice goes from 0.06 to 0.12 mm in diameter. Image 12 The Nozzle diameter goes from 0.15 to 0.40 in diameter. Create Part Automatic quantity Automatic Quantity is activated from the Create Part dialog box. Image 13 When this feature is activated the quantity input is disabled. The built in geometry recognition will recognize geometry with identical shape and set the quantity to the number of copies. Image 14 In this example there are two copies of A and C. The quantity setting of these parts will be 2. The other characters will have the quantity of 1. Image 15 This feature can be used if you want to use multiple cutting heads in Auto nesting. Auto technology in Single and Auto commands Note! This feature is only available for AWJ cutting! In IGEMS you can mix different lead-ins, lead outs and piercings in any combinations. This is a very good feature especially for users with great experience. For inexperienced users starting with IGEMS for the first time, all this settings sometimes can be confusing. To make the NC preparation even easier in AWJ-cutting we have added a new feature called Auto Technology. Page 7

8 Changes in the 2D-CAM module Image 16 You can switch between the User Technology and the Auto technology on the top of the dialog boxes for Auto and Single commands. The Auto technology can be used in all cases except for materials that need special piercings. IGEMS intension is to improve the functionality of the Auto technology in the future. Image 17 The general idea is to work with Dynamic Linear Piercing (Released in IGEMS R8). Fence in Sheet prepare One important task for the Sheet prepare command is to control the cutting order. To make it easier and more powerful to manually control the cut order we have added a new cut order algorithm called Fence. Image 18 The Fence option starts when you press the Apply button. Page 8

9 Changes in the 2D-CAM module Image 19 The cutting order will be in that order the Fence is intersecting with the parts. Image 20 IGEMS asks for the start point of the fence. (Point 1) Next Fence point (W=New start point, U=Increase radius, Y=Decrease radius) (Point 2) 1. The fence radius is pixel based, this means that you can control the fence radius relative to the parts by zooming in or out. 2. If you want to change the fence width, you can simply press U or Y. 3. The W will start a new fence. Parts in holes first Image 21 If the checkbox Parts in holes are activated then the cutting order are recalculated so that all parts located in holes are cut before the normal parts. Cutoff This is a new command in IGEMS. It can be used to cut off a sheet or to cut off parts. In previous versions this was possible by using a sequence of various commands. Image 22 The new Cutoff command has two modes depending if you want to cut off sheets or cut off parts. Page 9

10 Changes in the 2D-CAM module Image 23 Cut of sheets This feature can be used to make the scrap sheets easier to handle. It cuts large sheets of material into smaller pieces. Image 24 Use standard CAD commands and draw lines, arcs or polylines where the cutoff should be located. Start the command and select the cutoff objects. Image 25 This option has two settings. Image 26 These settings have following meaning. Page 10

11 Changes in the 2D-CAM module Image 27 Distance A must be larger than the Shortest cut to be used. The distance B (from the tool path to the part) is controlled by the value Distance to part. Cut of parts This feature can be used when you want to cut of parts. This kind of parts are probably not made by cutting, it is probably parts that already are manufactured. Do like follows: Create the part. Then make a line, arc or polyline object that describes the cutoff position. Image 28 Start the command and select the cutoff objects. Image 29 Page 11

12 Changes in the 2D-CAM module Image 30 The cutting starts at position A and stops at position B. The Jet will not turn off between the cut, it will move with the highest possible feed. This feed can be set in the machine setting dialog. Note! This feature needs modification of the postprocessor. Page 12

13 Bevel cut Chapter 4. Bevel cut Features in the Bevel cut commands are improved. It now works in different ways depending if machine type is set to waterjet or plasma. The feature has also got an Undo function. Note: The new functionality needs changes in the postprocessor! Loops on plasma cutting Cutting technology that creates heat need outside loops to get a good result. In previous versions of IGEMS the corner loops was added during the postprocessing. This could be a problem since the loop could damage other parts. IGEMS R9 now supports loops when adding the tool path. Image 31 The size of the loops is controlled from the input Loop radius in the dialog box. Image 32 The geometry of the lead is generated automatically (from a simple Line-Arc-Line geometry to and more advanced Arc-Arc-Line-Arc-Arc geometry). If the changes in cutting direction are less than 30 degrees, no loops will be added. Page 13

14 Bevel cut Image 33 Default size of the loop The default size of the loop can be set on each material. This is done in the material settings dialog. Image 34 Bevel with different angles It is now easier to add bevel cuts with different angles in one sequence. If you define several bevel cuts without closing the dialog box, you will get a question if previous toolpath should be connected with the new toolpath or not. Image 35 Page 14

15 Bevel cut If your answer is yes, then a loop is added. The changes of cutting angles will be done inside the loop. Image 36 Above you can see the result of 45 degree top bevel and 30 degree bottom bevel. Standoff in Plasma cutting Different material and different thickness require different standoff. The Standoff can have a big influence of the tool path. Image 37 On the picture above you can see that theoretical intersection point are moved with the distance of D when you move the Z-axis with the distance of A. The different standoff can be handled in different way on different machines. A. It can be handled completely by the CNC-controller. A common method is to use different kerf compensation to correct the D distance. B. Some CNC-controllers can correct the standoff by moving the tool in the Tool direction T. C. The standoff can also be handled by IGEMS. This result gives a toolpath with an offset from the theoretical intersection point. D. It is also possible to make a combination of these three methods above. The extra standoff is defined in the materials settings. Page 15

16 Bevel cut Image 38 Loops on WaterJet cutting In Water jet cutting technology we use inside loops. In previous versions of IGEMS the exact geometry of these loops were added during the postprocessing. Image 39 In IGEMS R9 the loops are generated when creating the toolpath. In the postprocessor the Loops are handled as special objects. This means that the postprocessors must be adjusted to be able to post files for IGEMS R9. Page 16

17 Bevel cut Image 40 The movement in corner loops will be as the picture above. Advance Bevel A new 3D-feature has been added to the Advance Bevel cutting command. This feature was added in IGEMS_R8 but never documented. Image 41 By using the 3D-Connect you can now add or delete connection lines in a 3D view. Image 42 Zoom, Pan and Rotate This command works in a different way from the rest of IGEMS. Page 17

18 Bevel cut Pan: Hold down the mouse wheel and move the mouse. Zoom: By rotate the mouse wheel. Rotate3D: By holding down the right button and move the mouse. Snap points You can add connection lines from bottom to top or opposite. Snap points on all endpoints and midpoints. You can also snap to closest point by select a snap point and then press Enter. Delete connections Image 43 By clicking on right mouse button you have options to delete and restore connections. Straight cuts in Advance Bevel To be able to make more complicated parts we have also added the functionality to add a 2D-cut within the Advance Bevel. Image 44 In the Advance Bevel you can define the top and bottom geometry. This information should not be enough if you want to cut a part as above. By using a polyline that describes a straight cut then this kind of geometries can be produced. To make this kind of part do like follows Page 18

19 Bevel cut Image 45 The Red object is the top geometry, the white objects is the bottom geometry. The straight cut has the color yellow. Define the parts in normal way then start the Bevel cut command. Image 46 The Cut object command allow you to follow a polyline, the cut will always be vertical. You can specify lead in, and side to cut. Multiple Advance Bevel Parts It is now possible to postprocess multiple Bevel parts in one CNC-file. Image 47 When you start the Advance Bevel post process Page 19

20 Bevel cut Image 48 Then you will have a question about zero points and a selection. If you want to control the cutting order between the parts, then select them by clicking. If the cutting order is not important then select the parts by a window. Image 49 The zero point and the cut order are displayed by temporary graphics. If you need to re-post then you must select zero point and cutting order again. Page 20

21 Organizer Chapter 5. Organizer It is now possible to search in what productions (nestings) a registered part are included in. Image 50 Example: The part above NIT-996 is already produced. The question is, in which production is it a member of. By double clicking on the part you can see following information. Image 51 On the Productions field list you can see in what production number the part has been manufactured. If the part is used in more than one production, then all productions will show in a list. Page 21

22 Organizer Image 52 If you go back to the main window and switch to Productions tab, you can see basic information about actual production. If you double click on the line you can see more information about the production. Image 53 This new feature makes it easier to trace old manufactured parts.
