This task shows how to easily
and quickly define the complete manufacturing program of a symmetrical
workpiece, when a symmetrical half of the workpiece is already
programmed. More information can be found in the Methodology section. |
|
 |
Open the
ProcessDEMO.CATProcess
document. The associated part is Left_Hand_Part.CATPart. The Left Program
contains 3 machining operations for machining a left hand part.
To machine the symmetrical right hand part, proceed as follows. |
|
 |
1. | Copy the Left Program in the
Part Operation using Edit > Copy and Paste
commands. Rename the new program as Right Program (using Edit > Properties).
|
| 2. | Select the Right Program node in
the tree and click TRACUT Operator
 in
the Auxiliary Operations toolbar (Transformation
Management Sub-toolbar). |
|
| 3. | In the TRACUT Operator dialog
box, select the Transformation type to Mirror. Click the Mirror selection field then select the YZ plane as the symmetrical plane. Click OK to create the TRACUT operator. |
|
| 4. |
Select the Right Program node in the tree and click Opposite
Hand Machining Options
 .
In the dialog box that appears, make sure that Reverse Machining Conditions command can be applied to all the operations types in the program. |
|
| 5. |
Click Reverse Machining Conditions
 .A message box appears giving the result of the command: numbers of operations processed and number of operations updated.
|
|
| 6. | Right-click the Right Program node in the tree and select
Compute Tool Path. The tool paths of the Right Program are recalculated. |
|
| 7. | Right-click the Right Program node in the tree and select Replay Tool Path. Make sure that the TRACUT display mode is active in the Replay dialog box. | |
| The replay shows the result of the opposite hand
programming.

| 8. | Save your document (ProcessDEMOResult.CATProcess, for example). | |
