|You can replay the tool path of a
complete manufacturing program or one or more operations of a program.
This task shows you how to replay a machining operation.
Please note that a number of settings for customizing Tool Path Replay are available in the Tools > Options > Machining > General tab.
|1.||Select an operation in the specification tree, then select Replay Tool Path . You can also right-click the operation and select Replay Tool Path.|
|The operation's tool path is computed
interactively and a progress bar appears giving the status of the
computation. You can interrupt the computation by clicking Cancel.
The following dialog box appears at the end of the computation. It contains a number of command icons for managing the tool path replay and material removal simulation. The name of the current operation appears in the title bar.
Information that appears in this dialog box includes:

|You can customize the function keys to the replay buttons in the CATMfgReplayToolPathPanel.CATRsc resource file.|
|9.||You can perform partial tool path replay for the
selected operation with certain display and visualization options of a
regular tool path replay.
The input to Start, Current and End positions can be done by either keying in the text boxes in the Replay positions area or selecting from the 3D graphics area. When you click the Start and End position push buttons, the complete tool path is visible temporarily so that desired position can be selected for providing the position input. When Current Position is selected only the tool path between the Start and End positions is shown.
In partial tool path replay, the tool path display is updated according to user input.
In partial/complete replay, the tool display can be updated by using the current position input.
See Partial Tool Path Replay Behavior for more information.

More About Tool Path Replay
Tool Path Replay Considerations
By default, the partial tool path replay positions are always displayed. Using the input boxes and selection push buttons, you can specify the Start, Current and End positions of the tool path replay.
The Current and End positions displayed are based on the activity
Partial tool path replay can be used for a single machining operation. Replay on Manufacturing Program is also possible and the partial replay positions are for the current operation being replayed. The inputs can be given with respect to the current operation by pausing the replay on Manufacturing Program.
Partial tool path replay is not available for multiple machining operations or auxiliary operations like tool change, transition paths, COPY Operator, machine rotation, and material removal simulation. For any unsupported activity, the replay positions are grayed out.
The information (feed rate, tool path point and tool axis, machining and total time) displayed at the bottom of the tool path replay panel, is consistent with the currently displayed tool path, even if it is partial
Visualization mode and color modes can be specified for partial tool path replay.
Partial tool path replay is not available in Plane by Plane, Feedrate by Feedrate and By Sectioning modes. If you switch to one of these modes, the positions are restored to full tool path and the editor boxes are grayed out. The behavior of these replay modes is then the same as for the complete tool path.
During continuous replay of partial tool path, the Current position spinner box is grayed out and once the replay is completed, the spinner box is updated with the Current position of the tool.
The Start position is always less than the End position. The Current position specified must be between the Start and End positions. The End position cannot be greater than the last tool path position. In case of input position error, the last valid position is retained.
If Start and/or End positions are modified and are both higher/lower than the Current position, the current position is reset to the End position.
All of the replay positions can be re-set to originally displayed values for the current operation by using the contextual menu on the position editor boxes.
When Color mode is set to Same Color in the Tool Path Replay dialog box, the tool path will be displayed in a single color. This color is decided by the setting in Color combo in the Graphic tab of the machining operation's Properties dialog box.
In the example below, the tool path will be displayed in green because green is selected in the Color combo of the Properties dialog box and Color mode is set to Same Color in the Tool Path Replay dialog box. If you want to change the tool path color, you must select the new color in the Properties dialog box.
When Color mode is set to Different Colors , the tool path will be displayed in various colors depending on the feedrates.
These colors are decided by the settings in the Color of feedrates combos in the Tools > Options > Machining > General tab. These settings will override the setting in the machining operation's Properties dialog box.
In the example below, the colors for approach, machining, and retract feedrates are set to yellow, burgundy, and blue in the Tools > Options dialog box.
The approach, machining and retract paths will be displayed in these colors because Color mode is set to Different Colors in the Tool Path replay dialog box.
Color of Transitions Paths between OperationsA transition path from operation A to operation B is represented by a dashed line whose color depends on the feedrate. This feedrate is determined as follows:
Color Coding after APT Import
When the tool path replay is done on a machining operation after an APT Import, color feedrate codes are not respected. This is because there is no information about the trajectory type (approach, machining , retract, and so on) in the APT file.
In the case, the trajectory with smallest feedrate value is arbitrarily assigned the machining feedrate color, the trajectory with next higher feedrate value is assigned approach feedrate color, and the trajectory with the next higher feedrate is assigned the retract feedrate color.
Computation depending on the Hide/Show status of selected elements
The following rules summarize the tool path computation behavior depending on the Hide/Show status of selected elements.
Influence of selecting 'By boundary of faces' or 'By belt of faces' option
A surface can be selected (both in Hide and Show modes) from the PPR tree using the 'By boundary of faces' option. However, selection from the PPR tree using the 'By belt of faces' option is not possible: selection must be done in the 3D viewer.
The reason for this difference in behavior is described below.
In all cases, the toolpath computation algorithm supports only a contour
By boundary of faces:
The edge contour is the external boundary of selected faces.
However, all faces must be topologically connex (they share their adjacent edges). The edges used by the toolpath computation algorithm exist in the design.
By belt of faces:
This situation is more complex because:
The edges used by the toolpath computation algorithm do not exist in the design. To get the contour of edges and the boundary of faces, it is projected onto the bottom plane of the bounding box of the belt, and the wireframe elements (including free vertices) are deleted.
When you select an object in the tree, you don't select the faces but the complete feature whose result can include more than one face. Those faces are not necessary built as a belt of faces. Moreover, the number and position of the faces included in the feature can be modified by the user. In this case, it may not be possible to compute the operation.
Selection from the PPR tree using the 'By belt of faces' option is not possible. Selection must be done in the 3D viewer.
Material Removal Simulation
You can use the Photo commands to simulate the material removed by machining operations in Photo mode (this is a P2 functionality).
You can use the Video commands to simulate the material removed by machining operations in Video mode (this is a P2 functionality).
You can use Check
Reachability to check the accessibility of the part on a machine.
Start Machine Simulation
If the NC Machine Tool Simulation product is installed, you can use Starts Machine Simulation to switch to the NC Machine Tool Simulation workbench. Please refer to the NC Machine Tool Simulation User's Guide for more information.
Note: The Starts Machine Simulation icon is not available if the too path replay is launched during machining operation edition. This is to ensure that simulation is available only if the operation definition is complete.
When the tool path replay is launched directly on a machining operation, then the Starts Machine Simulation icon is available.
