4 SAFETY PRECAUTIONS B-62824EN-1/01 SAFETY PRECAUTIONS When using NC data (Note) prepared using the software described in this manual, to control an actual NC machine, the following safety precautions must be observed. Precautions 1. Before attempting to use NC data to control NC machines, ensure that those machines and tools that will be under the control of the NC data will operate safely. If invalid NC data is used, or if NC data (confirmed as being satisfactory) is applied incorrectly, the machine and tool may behave unexpectedly, possibly damaging the tool, machine, and/or workpiece, and presenting the risk of injury to the operator and/or bystanders. 2. The software described herein does not check whether output NC data is fully compatible with the target machine. When using the output NC data to control an actual NC machine, Precaution 1 must be observed. 3. The software described in this manual does not check the compatibility of any software for making and checking drawings, based on NC data, with the target machine. When using the output NC data with an actual NC machine, Precaution 1 must be observed. 4. Due to deterioration of the storage medium, or as a result of errors introduced during communication, the NC data actually loaded into a machine may vary slightly from that originally created. Therefore, even when using NC data that has already been used successfully with an actual machine, Precaution 1 must be observed. Note) In this document, the term NC data refers to programs that specify NC machine operations. Note that in NC machine manuals, machining program, part program, or program may be used in place of NC data. Whenever using data that conforms to the definition of NC data as used in this document, irrespective of how it may be referred to in other documents, the above precautions must be observed. 1

27 2. FUNDAMENTALS B-62824EN-1/01 cutting distance data of each process. A machining process list is created by the NC data preparation function. *1 These data items are saved to a file by selecting [File => Save] or [File => Save As] from the menu bar, and are read at a time by selecting [File => Open] from the menu bar 2-12

28 2. FUNDAMENTALS B-62824EN-1/ Multiwindow What is the multiwindow? The multiwindow is a function for opening multiple drawing windows at a time. By setting a varied display range and display scale for each window, different figures can be displayed side by side, and an overall drawing and detailed drawings can be displayed at a time. Moreover, by changing the view directions of windows one by one, a figure and tool path can be displayed in many different directions. Thus, the user can easily grasp a three-dimensional overall image Using the multiwindow The multiwindow function can be used with the commands of the [Window] menu on the menu bar. For example, the [1 Window] to [4 Window] commands can display one to four drawing windows easily. In this case, the view direction of each window conforms to the standard value defined by Symbolic CAP T. In addition, a three-dimensional image can be viewed in a desired direction by using the [Set View Direction] command of the [View] menu together with the multiwindow function. 2-13

29 2. FUNDAMENTALS B-62824EN-1/ Machining Planes What is a machining plane? A machining plane represents the highest classification information for determining which area of a blank is to be machined and how the area is to be machined. Before parts figures and machining figures can be created, a machining plane where those figures are to be created must be selected. Machining planes are classified as follows: Turning plane On a turning face, parts figures for turning can be created, and turning machining definition can be performed. The coordinates of each figure are specified using Z and DX (= X diameter value). On this face, machining figures for C/Y axis machining cannot be created. Facing plane (front face) On an facing face, machining figures for end facing can be created, and end facing machining definition can be performed. The depth of an end facing from the plane of the blank can be specified using [Machining Surface Height]. The coordinates of each figure are specified using DX and Y. Side plane On a side plane, machining figures for side facing can be created, and side facing machining definition can be performed. A separate machining plane is defined for each C-axis index angle. The depth of a side plane from the surface of the blank can be specified using [Machining Surface Height]. The coordinates of each figure are specified using Z and Y. Cylindrical plane On a cylindrical plane, machining figures for cylindrical facing can be created, and cylindrical facing machining definition can be performed. A separate machining plane is defined for each cylinder radius (usually equal to the radius of a blank to be machined). The coordinates of each figure are specified using Z and C (angle in degrees). Among the machining planes mentioned above, the turning plane and facing plane (front) are provided from the beginning, so the user can switch between them easily. On the other hand, an infinite number of faces are possible for the side plane and cylindrical plane, depending on the index angle and cylinder radius, so that these machining planes are not provided from the beginning. These machining planes can be created freely. So, 2-14

30 2. FUNDAMENTALS B-62824EN-1/01 the user first creates required machining planes, then can switch between them Setting a machining plane To set a machining plane, select [Auxiliary => Machining Plane => Setting] from the menu bar, or click the [Machining Plane setting] button on the tool bar. [Turning Plane] is selected in the initial state, that is, immediately after Symbolic CAP T is started or [File => New] is selected from the menu bar. To switch from the currently selected machining plane to another, select a desired machining plane from the list of machining planes, then clock the [OK] button. When selecting [Facing plane (Front Face)] or [Side plane], also specify a value for [Machining Surface Height]. To create a side plane or cylindrical plane, click on the [Edit Custom Planes] button. Select a desired type of machining plane. When [Side plane] is selected, click the [C-Axis Index Angle]. When [Cylindrical plane] is selected, enter a value for [Cylinder Radius], then click the [Add] button. Press the [Edit Custom Planes] button also to delete side faces and cylindrical planes no longer required. Select a desired machining plane from the list of machining planes, then click the [Remove] button Displaying all machining planes simultaneously When a machining plane is selected, only those parts figures and machining figures that are present on the machining plane can be viewed. In routine work, this mode of display is sufficient. However, all figures should be displayed to grasp the entire image. To display the figures on all machining planes except cylindrical planes at a time, select [View => View All Machining planes] from the menu bar, or click the [View All Machining planes] button on the tool bar. The concept of the coordinate system for cylindrical planes differs from that for the other machining planes, so that cylindrical planes cannot be displayed together with the other types of machining planes. To view the figures that are present only on a specific machining plane again, reselect the machining plane. 2-15

31 2. FUNDAMENTALS B-62824EN-1/ Relationship between machining planes and the multiwindow Only one drawing window is displayed in the initial state, that is, immediately after Symbolic CAP T is started or [File => New] is selected from the menu bar. In this case, when a machining plane is selected, the front view of the plane is always displayed. When the multiwindow function is used, each drawing window is displayed as described below. The [1 Window] command displays the front view of the currently selected machining plane. The [2 Window] command displays the currently selected machining plane, and a three-dimensional drawing viewed from a slant direction (referred to as a three-dimensional view). The [3 Window] command displays the currently selected machining plane, a drawing viewed from an facing plane direction, and a three-dimensional view. The [4 Window] command displays the currently selected machining plane, a drawing viewed from an facing plane direction, a three-dimensional view, and a drawing viewed from the side plane 0-degree direction. In any case, note that the machining plane remains unchanged on all drawing windows. That is, the system has only one current machining plane, and the multiwindow function simply displays drawings of the machining plane viewed from different directions. 2-16

32 2. FUNDAMENTALS B-62824EN-1/ Layers What are layers? With layers, the user can view complicated machining and figures and make arrangements and checks more easily. Layers are not needed for simple figures, but are useful for handling complicated figures. Layers can be compared to multiple sheets of transparent paper overlapping one another; one layer corresponds to each sheet of paper. By specifying which layers to use for figure creation and which layers to use for display, the user can grasp an overall image and can also view details Major classification of layers Layers are classified into two major types according to their application. Drawing layer Drawing layers are used to create figures; 256 layers are available. Blank figures, parts figures, and machining figures are automatically assigned to layer No. 129 and up. Figure entities (such as points, straight lines, circles, and arcs) created in the figure creation mode of the side menu are assigned to layer No. 1 by default. [Show], [select], and [Layer Name] can be set for each layer. For only one of all layers, [Draw] can be specified. NC data preparation layer When NC data is prepared, the NC data preparation layer is used to display a tool path. On this layer, no figures can be created. The user can select whether or not to display this layer Setting drawing layers The settings described below can be made for 256 layers by selecting [Auxiliary => Layer => Setting] from the menu bar or by clicking the [Layer Setting] button on the tool bar. [Draw] Specify a layer number for registering figure entities created in the figure creation mode of the side menu. Only one of the 256 layers can be specified. [Show] Layers to be displayed on the screen can be specified. The figures of the specified layers are displayed, overlapping one 2-17

[Select] Whether to make the figure entities displayed on the screen selectable can be specified. If an entity is specified as being unrecognizable, the entity cannot be selected even when displayed. [Layer Name] A desired name can be assigned to a layer Relationship between layers and the multiwindow The system allow only one package of draw, show, select, and layer name settings. Note that even when the multiwindow function is used, these settings cannot be made for each drawing window Relationship between layers and machining planes When a machining plane is selected, only those figures that are present on the machining plane can be viewed. This capability is implemented using the drawing layer function. Among the 256 layers, the latter 128 layers are reserved for the system to manage machining planes and various figures (blank figures, parts figures, machining figures). So, be careful when creating figure entities such as points, straight lines, circles, and arcs in the figure creation mode in this range of layers. That is, the user can specify drawing layer No. 129 and up, but figure entities thus created may or may not be viewed, depending on machining plane switching operation. 2-18

34 2. FUNDAMENTALS B-62824EN-1/ Interference Check This section explains the interference check function usable for NC data preparation What is the interference check function? The interference check function checks, during NC data preparation, whether the tool paths for contouring, pocketing, and grooving interfere with machining figures. The occurrence of an interference is assumed in the following two cases: (1) When moving along its tool path, the tool interferes with a machining figure in the tool radial direction. Example: In pocket side face finishing, a specified machining start point is inadequate. Work Machining Figure Tool Approaching Tool interferes with Machining Figure Machining Start Point (2) When moving along its tool path, the tool interferes with a machining figure in the tool axial direction. Example: In pocket side face finishing, a specified approach radius is excessively large. 2-19

FUNDAMENTALS B-62824EN-1/01 Machining Figure Tool Work Machining Start Point Tool-Axis In-Feed Macining Tool interferes with Machining Figure Tool-Radius In-Feed Approaching If a check finds that an interference occurs, the system outputs the tool path of the interfering tool, then stops NC data preparation after displaying an error message. The interference check function does not make a check in a cutter compensation mode (G41/G42). (A cutter compensation mode is output when NC-based cutter compensation is specified as a condition set for cutting such as pocket side face finishing.) Whether to use the interference check function can be determined on the NC data preparation setting screen Using the interference check function On the NC data preparation screen, open the NC data preparation setting screen, then specify [Interference Check for C/Y]. Note 1) When the user selects to make an interference check, a longer time is required for NC data preparation due to check processing. Note 2) No interference check is made in a cutter compensation mode, regardless of whether the use of this check function is set. 2-20

It also describes tool paths for which no canned cycle is used. Clicking the [Cutting Conditions] button for the [Set Machining Conditions] dialog box displays a dialog box for setting cutting conditions. Canned cycle For hole machining, it is possible to prepare NC data in which canned cycle commands are used. Whether to use canned cycles is determined according to the setting of NC machine files. Refer to Chapter 14 of "Basic Module Operator's Manual" (B-62824EN) for details. If [Set Feedrate for Start/End] is turned on, no canned cycle commands are used regardless of the setting of the NC machine file used, however. Refer to the operator's manual for the respective CNC units for the tool path when canned cycles are used. 6-18

233 6. MACHINING DEFINITION B-62824EN-1/ Cautions for Use and Restrictions If a machining figure is deleted, machining data related to the deleted machining figure is also deleted automatically. If a machining figure is deleted by mistake, it can be retrieved using the undo function on the toolbar. If a machining figure is changed, machining data related to the changed machining figure may become unsuitable for the machining figure. If you have changed a machining figure, check the process data before preparing NC data. If you change tool data in process data-01 for a machining process, cutting conditions in the other process data (such as process data-02) for the same machining process may become unsuitable for the changed tool data. If you have changed tool data in process data-01, be sure to check the other process data (such as process data-02) before preparing NC data. If you reselect a machining figure in process data-01 for a machining process, the other process data (such as process data-02) for the same machining process may become unsuitable for the reselected machining figure. If you have reselected a machining figure in process data-01, check the other process data (such as process data-02) before preparing NC data. If you define overlapping island figures in pocketing (side face finishing), make definitions so that the bottom face height of the upper island figure levels with the top face height of the lower island figure. If you fail to follow this definition rule, the tool path preparation or interference check function may not work correctly. If a value larger than 0 is input as the cut-in angle in pocketing (side finishing), no check is made for interference between the oblique cut-in operation and the pocket figure or island figure. In this case, the operator must be very careful not to cause interference. If a pre-hole figure is prepared after a value larger than 0 is set as the cut-in angle in pocketing (roughing/bottom face finishing) or grooving (roughing/bottom face finishing), the cut-in angle will not automatically be re-set to 0 degrees.

234 6. MACHINING DEFINITION B-62824EN-1/01 If the same tool is used in end and side face machining data, the automatic T code setting function sets the same tool number. If the same tool number is used in turning process data and C/Y axis machining process data, the system does not check for it

235 7. AUTOMATIC PROCESS SPECIFICATION B-62824EN-1/01 7. AUTOMATIC PROCESS SPECIFICATION Automatic process specification is a function which automatically defines an entire process on the basis of defined machining figures and relevant machining information (hole figure library and milling library) Automatic Process Specification Screen On the machining definition list screen, click the process list for new machining appears. button. A...Starts automatic process specification. Machining is determined for all relevant machining figures, based on the internally prepared figure sequence data. An explanation of how to determine the machining type and machining data is given below. To first obtain the sequence of the figures for which machining will be determined, click the [Setting...] button before clicking this button. The figure sequence for a new process is then determined and listed....stops automatic process specification. Determination may not stop immediately. Once determination has been stopped, the process determined up to that point is displayed. 7-1

236 7. AUTOMATIC PROCESS SPECIFICATION B-62824EN-1/01... Displays the figure sequence data setting screen....saves the automatically determined process and exits from automatic process specification. The previous process is discarded. Clicking this button before the start button clears the system to enable the definition of new machining. If the determined process includes pocket or groove figures, pre-hole figures are automatically created as required, and any existing pre-hole figures are discarded.... Restores the previous process and exits from automatic process specification.... If automatic process specification is started with either of these check boxes checked, automatic process sort is performed immediately after process determination. See the next chapter for details of automatic process sort. (Note) If automatic process specification is started with either of these check boxes checked, "alternation in descending order of machining figure position height" is always added to the conditions for automatic process sort. Therefore, even if the sequence is changed so that a figure having a lower position is executed before a figure having a higher position, by using the figure sequence data setting screen, automatic process specification re-sorts the figures into descending order of position height. 7-2

239 7. AUTOMATIC PROCESS SPECIFICATION B-62824EN-1/ Automatic Determination of Machining Data Machining data is automatically determined as follows, for each machining type, set during manual machining definition or automatic process determination. (1) Machining conditions (a) Tool data Tool data is automatically selected from those tools registered in the tooling data selected during pre-machining setting, according to the parameter settings. See "Automatic determination of tool data" for details of the automatic selection of cutting tools. (b) Cutting conditions The cutting conditions are automatically determined from the tool material and dimensions in the automatically selected tool data, and from the cutting condition library data and parameter setting data registered for the relevant machining type. Data which is determined mainly from the workpiece material and tool to be used, such as the cooling method, spindle speed, feedrate, and maximum cut-in depth, is automatically determined from the tool data and cutting condition library data. See the description of the cutting conditions for details of the cutting condition library data to be registered for each machining type, and how to calculate the cutting conditions. Data which is not related to the workpiece material, such as the clearance, escape method, and escape amount, is automatically determined from the parameter setting data. See the description of parameter setting for details of parameter setting data to be registered for each machining type. (c) Machining start position The machining start position is automatically determined from the tool mounting position in the automatically selected tool data and the index position specified during pre-machining setting, as follows: Machining start position = Tool mounting position + Index position Pass points are not determined automatically. 7-5

240 7. AUTOMATIC PROCESS SPECIFICATION B-62824EN-1/01 (2) Start point Start point data for pocket roughing and bottom face finishing, and that for groove roughing and bottom face finishing, are automatically determined from the machining figure data and machining conditions, as follows: (a) Pocket roughing and bottom face finishing For a pocket having a cavity figure or open entity, the start point is automatically determined inside the cavity figure or outside the pocket. For a closed pocket having no cavity figure, the start point is automatically set to the position from which the tool path in the pocket is created. (b) Groove roughing and bottom face finishing The start point is automatically set to that position from which the center figure of the groove is started. (3) Island figure setting data An island figure, created as part of the machining figure creation process, is automatically determined as that island figure which sets data for roughing, bottom face finishing, and side face finishing for the relevant pocket figure. The finishing allowance for the island for pocket roughing is automatically determined from the finishing allowance for pocket roughing, registered in the cutting condition library data. (4) Cutting range The cutting ranges for pocket side face finishing and contour roughing, bottom face finishing, and side face finishing are automatically determined as follows: (a) Cutting range All side faces of the machining figure, excluding the open entity of a pocket 7-6

241 7. AUTOMATIC PROCESS SPECIFICATION B-62824EN-1/01 (b) Start point of cutting range For a machining figure having an open entity For a machining figure having an open entity, an end point of a nonopen entity becomes the start point of the cutting range. For a machining figure having no open entity For a pattern figure for which the inside is to be cut, the midpoint of an edge of the rectangle becomes the start point of the cutting range. For a groove figure, the midpoint of the entity adjacent to the semicircle entity at an end of the groove becomes the start point of the cutting range. For other figures, including a special figure created by symbolic input, the start point used for creating the machining figure becomes the start point of the cutting range. 7-7

265 8. AUTOMATIC PROCESS ALTERNATION B-62824EN-1/ Sort Conditions Some alternation conditions are prerequisites and are always observed. Some other conditions may or may not be observed, depending on the object of the process alternation Conditions that are always observed (1) The function always groups processes according to the target machining plane (end plane, side plane, cylindrical plane). If the machining of two or more planes is defined in a random order, this function groups the machining processes for the individual planes according to the order in which the planes are encountered. (2) If two or more machining instructions are specified for a single machining figure, the function will not change the order of those instructions. If, however, pre-hole machining is defined after the corresponding main machining, such as pocketing or grooving, the function alternations the functions such that the pre-hole machining is performed before the main machining Conditions that can be specified according to object (1) (Condition 1) Sorting into decreasing order of height of location of machining figure The function alternations the machining processes for end planes into decreasing order of the height of the location of machining figure along the Z-axis. The machining processes for side planes or cylindrical planes are alternation into decreasing order of the height of the location of the machining figure along the X-axis. (2) (Condition 2) Sorting according to tools (tool optimization) If two or more machining processes for a single machining plane use tools having identical T codes, the function groups those processes and optimizes the tool order. The function groups the processes into the order in which the corresponding tools are encountered. When (Condition 1) is selected, the function optimizes the order of the tools used for machining at a single height. 8-2

266 8. AUTOMATIC PROCESS ALTERNATION B-62824EN-1/01 (3) (Condition 3) Sorting according to tools used for machining on all side faces (tool optimization for machining on all side planes) If the machining of two or more side planes is defined, the function groups the processes according to the tools used on the side planes and optimizes the tool order. The function, however, does not change the order of the machining on each side plane. In addition, the function alternations the processes in such a way that the minimum number of changes in the machining planes occur when the tools are replaced. When the [Automatic Process Sort] screen appears, these three conditions are set to their initial statues (enabled or disabled) specified as described in Section 14.1, "Parameter Setting for [C/Y] Automatic Process Determination." The same occurs when the [Fully Automatic Process Determination] screen appears Combining three conditions (1) When all three conditions are enabled Sorting procedure 1The function alternations the processes into decreasing order of the height of the location of the machining figure. 2The function optimizes the order of the tools used for the machining of a single machining plane at a single height. 3If the machining of two or more side planes is defined, the function optimizes the order of the tools used for those side planes. (2) When two conditions are enabled Sorting procedure 1The function alternations the processes into decreasing order of the height of the location of the machining figure. 2The function optimizes the order of the tools used for the machining of a single machining plane at a single height. 8-3

267 8. AUTOMATIC PROCESS ALTERNATION B-62824EN-1/01 Sorting procedure 1The function alternations the processes into decreasing order of the height of the location of machining figure. 2If the machining of two or more side planes is defined, the function optimizes the order of the tools used for those side planes. Sorting procedure 1The function optimizes the order of the tools used for machining a single machining plane. 2If the machining of two or more side planes is defined, the function optimizes the order of the tools used for those side planes. (3) When a single condition is enabled Sorting procedure 1The function alternations the processes into decreasing order of the height of the location of the machining figure. Sorting procedure 1The function optimizes the order of the tools used for machining a single machining plane. Sorting procedure 1If the machining of two or more side planes is defined, the function optimizes the order of the tools used for those side planes. 8-4

292 12. MILLING LIBRARY B-62824EN-1/ MILLING LIBRARY This chapter describes a milling library that is referenced when preparing machining figures other than hole figures Overview In Symbolic CAP T, a machining process registered for a machining figure other than a hole figure is defined as milling data. When creating a machining figure other than a hole figure, select the corresponding milling data that has been registered in advance. In fully automatic process determination for machining definition, the milling data specified for a machining figure is referenced to create the data for a milling process. For the milling library, functions for registering and deleting the milling data to be referenced when creating a machining figure, and a function for editing the machining process data, are supported. The milling data is registered according to the target machining figure type. Milling data registration Machining figure preparation Milling data 1 Contour figure 1 (For contour figure) Milling data 1 Roughing Roughing Bottom finishing Bottom finishing Side finishing Side finishing Milling data 2 Fully automatic process (For pocket figure type) determination Roughing Bottom finishing Machining process for contour figure 1 Side finishing Roughing Ф10 Bottom finishing Ф10 Milling data 3 Side finishing Ф8 (For groove figure) Roughing Milling library 12-1
