This task shows you how to update the input stock manually
for the machining operations in a lathe manufacturing program.
These machining operations can be lathe operations, and
axial operations along the spindle axis.
In Manual mode, the input stock takes into account all the previous operations. The lathe and axial operations must be completed.
Please refer to How to Update Input Stock for more information about this capability.
|1.||Select File > Open then select the StartStockUpdateManualMode.CATProcess document|
Select Machining > Lathe Machining from the
The Lathe Machining workbench appears. The part is displayed in the Setup Editor window along with the manufacturing specification tree.
Double-click Part Operation.1 in the tree to display the
Part Operation dialog box.
|4.||Double-click the second lathe operation in the program: External lathe recessing.|
In the Geometry page, the status is red because there is
no input stock defined for the operation.
Select the Update Input Stock command by
either clicking the icon
or right-clicking the Input stock status field
in the sensitive icon. The stock is computed and the corresponding
sketch profile is displayed in the viewer.
Select this profile as the input stock for the operation.
The Geometry page is updated with this stock
Click the Replay icon
to verify the operation.
Click OK to accept the operation.
The status of the operation is as follows:
|10.||The input stock of the other Lathe operations in the program can be updated in the same way.|
For modifications to the Part Operation, a previous operation in the program (edit), or a previous sequence of the program (delete or copy/paste), the stock status becomes Stock to update.
After modifications, there is no automatic refresh of the stock status of the operations. You can right-click the Program in the tree and select the Update Computed Stock Status contextual command. This will refresh the stock status of all the operations.
Please note that when you copy/paste an operation, the input stock is not copied.
Removing Input Stock
If you right-click the Input stock status
field in the Geometry tab page, you can use the Remove
Input Stock contextual command to remove the
operation's input stock. The corresponding sketch profile
will be deleted. The status of the previously selected geometry
from the deleted sketch will be Not found, so new
geometry must be selected in this case.
The user can compute the final stock after the last operation in the Program has been performed. This is done using the contextual menu of the Program, which includes a Compute Final Stock command.
The generated IPM Stock body will be stored under the
Product List in the PPR tree with the name:
Prior to V5R18, the user had to create a dummy operation in order to get the stock after the last operation in a Program. The Compute Final Stock command eliminates this needless activity.
