|This task shows how to insert a Thread Turning operation in the program. To create the operation you must define:|
|Open the Lathe01.CATPart document, then select Machining > Lathe Machining from the Start menu. Make the Manufacturing Program current in the specification tree.|
Thread Turning icon
A Thread Turning entity along with a default tool is added to the program.
|The part in the icon is colored red indicating that this geometry is required.|
|2.||Click the red part in the icon then select the desired part profile in the 3D window.|
|3.||Specify the desired length of threading.|
|4.||Select the Strategy tab page
to specify the main machining parameters that are organized in three tabs:
Thread, Strategy and Options.
Set the following values in the Thread tab:
Other optional parameters can be set in the Strategy and Options tabs.
|5.||If you want to generate CYCLE statements, you must select the Output CYCLE syntax checkbox in the Options tab and set the Syntax Used option to Yes in the NC Output generation dialog box. Otherwise, GOTO statements will be generated.|
|6.||A tool is proposed by default when you want to 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 a Lathe Operation.
|7.||Select the Feeds and Speeds tab
to specify the machining spindle speed for threading.
Feedrates in units
per minute are available for air cutting such as macro motions and path
|8.||Select the Macros tab
to specify the operation's transition paths (approach and retract motion,
See Define Macros on a Lathe Operation for an example.
|9.||Before accepting the operation, you should check its validity by replaying the tool path.|
|10.||Click OK to create the operation.|
Example of output
If your PP table is customized with the following statement for Thread Turning operations:
A typical NC data output is as follows:
The parameters available for PP word syntaxes for this type of operation are described in the NC_LATHE_THREADING section of the Manufacturing Infrastructure User's Guide.
