|This task shows how to insert a Thread
without Tap Head operation in the program. To create the operation you
HoleMakingOperations.CATPart document, then select the desired
Make the Manufacturing Program current in the specification tree.
Select Thread without Tap Head
A Thread without Tap Head entity along with a default tool is added to the program.
The Thread without Tap Head 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
the following machining parameters:
The other parameters are optional in this case.
|5.||A tool is proposed
by default when you create a machining operation. If the proposed tool is
not suitable, just select the Tool tab page
to specify the
tool you want to use. This is described in
Edit the Tool of an Operation.
You can use a boring bar or a tap in this type of operation.
Feeds and Speeds tab page
to specify the
feedrates and spindle speeds for the operation.
Note that in the toolpath represented in the strategy page, tool motion is as follows:
|7.||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.|
|8.||Click OK to create the operation.|
|Example of output
If your PP table is customized with the following statement for Thread without Tap Head 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_THREAD_WITHOUT_TAP_HEAD section of the Manufacturing Infrastructure User's Guide.
