|This task shows how to insert a Reverse
Threading operation in the program.
To create the operation you must define:
HoleMakingOperations.CATPart document, then select the desired
Make the Manufacturing Program current in the specification tree.
Select Reverse Threading
A Reverse Threading entity along with a default tool is added to the program.
The Reverse Threading dialog box appears directly at the Geometry tab page .
|2.||Select the red
hole depth representation then select a threaded hole feature in the 3D
Just double click to end your selection.
The sensitive icon is updated with the following:
You can modify this data.
|3.||If needed, you can invert the tool axis direction by selecting the axis representation in the sensitive icon.|
Strategy tab page
to specify the
following machining parameters:
The other parameters are optional in this case.
|A tool is proposed by default when you want to create a machining operation.|
Feeds and Speeds tab page
to specify the
feedrates and spindle speeds for the operation.
Note that in the tool path represented in the strategy page, tool motion is at:
|6.||If you want to specify approach and retract motion for the operation, select the Macros tab page to specify the desired transition paths. The general procedure for this is described in Define Macros of an Axial Machining Operation.|
|Before accepting the operation, you should check its validity by replaying the tool path.|
|7.||Click OK to create the operation.|
|Example of output
If your PP table is customized with the following statement for Reverse Threading operations:
A typical NC data output is as follows:
You can use Edit Cycle to edit or choose output syntaxes. For more information please refer to Editing Cycle Syntaxes in Axial Machining Operations.
The parameters available for PP word syntaxes for this type of operation are described in the NC_REVERSE_THREADING section of the Manufacturing Infrastructure User's Guide.
