What's New?New FunctionalitiesNC Program Review From a Manufacturing Program or a Part Operation selection in the PPR tree, the new Process Table command activates a Process View in which the various operations of the Manufacturing Program or Part Operation are presented in a table format. If no pre-selection is performed, the Process Table shows the detail of all the Part Operations of the Process document.

Enhanced FunctionalitiesNC ResourcesMachine definition For machines created using the Machine Tool Builder product, the Machine Editor is enhanced to centralize all NC output options. If such a machine is defined on the Part Operation, all options for NC data generation can be read automatically from the machine definition. Enhanced Tool Assembly definition Several diameters can now be defined on the tool holder of a tool assembly. Enhanced Tool Assembly Viewer Mill and Lathe tool assembly viewers are now updated according to geometry parameter modifications. Improved feeds and speeds units for tool definition New linear spindle speed attributes for cutting speeds (m/mn and ft/mn) and angular feedrate attributes for feedrates (feed/tooth * number of flutes). Better feeds and speeds management with TDM If the TDM connection is available, feeds and speeds are displayed according to the specified machine tool and material. Tool Corrector management with TDM If the TDM connection is available, capability to read tool correctors from TDM and assign them to tools.

Improved Pack/Unpack of Tool Paths Multi-selection of operations to pack their tool paths. The Packed status of a tool path is indicated in the PPR tree. Enhanced PP instruction management You can now increase the size of dialog boxes displaying PP Instructions. A contextual menu with Cut/Copy/Paste/Undo/Select All commands provides edition facilities for PP instructions. Machining Axis System definition enhancement The origin of the Machining Axis System can be defined from a set of coordinates in addition to the point selection capacities that already exists. Tool Path Editor A new command in the Point Modification toolbar allows you to insert a point in the tool path. Also capability to create geometry from a tool path.



Page 10

Geometry ManagementEdge selection The capabilities for selection of edges are now more consistent between Machining workbenches and machining operations. Easier Face selection New capabilities are offered when the Face Selection toolbar is displayed (selection by trap, paint stroke, and so on). Show/Hide capability for part and check surfaces For machining operations that use part and check surfaces, you can now choose to show or hide that geometry using toolbar icon commands. Remove unwanted geometry New capability in the Geometry Analyser dialog box allows you to remove unwanted or unused geometry (for example, lines that were automatically inserted in guides). Hybrid body support Solid and surface geometries can be created in a new body entity called 'hybrid body'. Machining workbenches support hybird bodies (for example, geometry to be machined or geometry selected as stock for material removal simulation).

Replay and SimulationEnhanced tool positioning in tool path replay You can now display the tool at a selected point on the tool path. This behavior can be set under the Tools > Options > Machining > General tab. Better visualization of feedrate between two operations In a tool path replay, the path joining two operations is no longer displayed as a broken white line, but is colored as a rapid motion (red) or depending on the next motion (yellow for approach, for example). Customize colors of machining, approach and retract paths The colors of paths in the Different colors replay mode can now be customized under the Tools > Options > Machining > General tab. Improved tool path replay in By plane mode Visualization is improved: only the tool path of the current plane is displayed along with approach and retract motions. Geometry accuracy in Photo/Video You can now set the stock tessellation tolerance in the Part Operation dialog box. In previous releases, this tolerance was fixed at 0.2mm. Possibility to store several Video Results on a program A new setting in Tools > Options > Machining > Photo/Video allows you to have video results stored on more than one operation in the program. Optimized rendering for Video simulation of Turning operations The Optimized rendering for Video setting under Tools > Options > Machining > Photo/Video for improved simulation performance is now valid for turning as well as milling operations. Direct access to Video simulation from Manufacturing Program An icon command on the Manufacturing Program editor allows direct access to Video simulation.

NC Data OutputRemove GOTO before cycle statements For axial machining operations using SYNTAX output mode (CYCLE), you can now choose whether or not to output GOTO statements corresponding to Jump and Clearance motions. Tool Change Point management For machines created using the Machine Tool Builder product, the tool change point referenced in the Part Operation is read from the machine and cannot be edited. Tool Center Point output



Page 11

The tool center point for ball-end tool can now be set as Tool output point in Tools > Options > Machining > Output. APT output accuracy for large parts You can now specify different formats (number of digits and digits after the decimal point) for coordinates and vector components. Double points option for NC data output You can now choose to keep or remove points that are repeated after PP statements.

PLM IntegrationSimplified user interface in Manufacturing hub context The user interface is simplified by removing fields requesting the user to specify input or output file paths. Document Chooser integration and support of DLNames You can now customize the document environment in order to select documents or paths using various interfaces (folder, SmarTeam, and so on). The interface can be customized for a folder or DLName path selection interface.

You can click Undo if you want to cancel the auto-sequence results. It is possible to impose a constraint (called strong precedence) to force a group operations to remain together after sequencing. Applying a strong precedence constraint means that in addition to imposing an order between two operations A and B, it is not possible to have another operation C between them. The sequence A - C - B is not allowed, only A - B is allowed if a strong precedence exists between A and B. For this, a parameter named Strong must be added to operation B. For example, in auto-sequencing this could be used to prevent inserting a threading operation between a drilling operation and a reaming operation. Machining axis changes are taken into account in auto-sequencing without having to impose strong precedence criteria.

Create a Machining ProcessThis task shows how to create a machining process containing a sequence of axial machining operations: Spot Drilling, Drilling, and Tapping. For each operation you can associate Knowledgeware expressions such as formula and checks and specify a tooling query. This enables to establish relations on data such as features, machines, and tools that are not yet known at machining process build time. For example, you can use this capability to determine the depth of cut from the hole depth. In addition, you can use f(x) capability to link the various parameters of machining operations. For example, for an machining process where a rework phase follows a roughing phase, the offsets of the rework can be determined from the offsets used in the roughing step. Click here to see how you can make use of Knowledgeware functionalities in machining processes. A formula is an expression associated to a machining operation or a machining feature attribute, which will be converted to a f(x) formula when the machining process is applied. A check is a logical expression associated to the corresponding machining operation. In a check, and and or operators are available. Between several checks, an and operator is applied. When the machining process is applied, the checks list is solved, a logical status is returned, and the operation is created if the status is true. A tooling query comprises one or more expressions that are used to find an appropriate tool for a given operation. Select an NC Manufacturing workbench from the Start menu. No CATPart or CATProcess is needed at this stage. If the Machining Process toolbar is not already displayed, select it using View > Toolbars. Make sure that Start Edit mode is set in Tools > Options > Machining > Operations.

Scale: select a planar surface or a point and a scale factor to be applied along the normal projection on the selected element. Matrix: This transformation will be defined by the matrix definition of the transformation in the absolute axis system, the current machining axis system, or a selected machining axis system. In case of definition of the matrix in the absolute axis system or in the current machining axis system, the matrix of the transformation is stored in the model in the absolute axis system (it is invariant in this axis system). Choosing one or the other mode only changes the display of the coordinates of the matrix. Out of a current machining axis system context, the absolute axis system will be used to display the matrix. In case of definition of the matrix in a selected machining axis system, the matrix of the transformation is stored relatively to this selected machining axis system.

Insert a Copy Transformation InstructionThis task shows how to apply a Copy Transformation instruction to operations in the program. Open the CopyTransfoSample.CATPart document. 1. Create a first Pocketing operation on the first square cut-out, then a second Pocketing operation on the first triangular cut-out. To create these pockets, make sure that the Island Detection contextual command is not active when define the pocket bottom. 2. In the specification tree, select the second Pocketing operation. Select the Copy Transformation Instruction icon .

A Copy Transformation instruction is inserted in the program after Pocketing.2 and the Copy Transformation dialog box appears. 3. Click the Add Operations icon tree. then select the two Pocketing operations in the specification

The Copy-Transformation will apply to these two operations. Selected operations must have the same tooling

NC Data Output ConsiderationsAllow Copy Transformation to produce an output during MfgBatch taking into account specificities of the referenced machining operations (Cycle syntax or Goto statements, Compensation, Profile, Tip/Axis, Contact/Norm, PQR, and so on). During NC Code generation, the tool path of the Copy Transformation of an ordered list of machining operations, will for each of its sub-paths corresponding to a specific reference machining operation read the complementary information on this machining operation to associate then to the particular treatment of this sub-path. If the Cycle Syntax is ON on a reference machining operation, the sub-path will be output is this mode. The tolerance and discretization step of reference machining operation are taken into account to process double points for this sub path. If profile data exist on a reference operation, the sub path will be output in this mode. Compensation data will be read for this sub path on the reference machining operation. The output of the Copy Transformation will take into account both data available in the tool path and in the reference machinin
