Create a Parallel Contour Rough Turning Operation

task target This task shows how to insert a Parallel Contour Rough Turning operation in the program.

To create the operation you must define:

pre-requisites Open the Lathe01.CATPart document, then select Machining > Lathe Machining from the Start menu. Make the Manufacturing Program current in the specification tree.  
scenario 1. Select the Rough Turning icon .

A Rough Turning entity along with a default tool is added to the program.

The Rough Turning dialog box appears directly at the Geometry tab page . 
This tab page includes a sensitive icon to help you specify the geometry to be machined. 
The part and stock of the icon are 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.

Select the stock in the same way.
3. Select the Strategy tab page to specify the main machining strategy parameters:
  • Roughing mode: Parallel Contour
  • Orientation: External
  • Location: Front
  • Machining direction: To head stock.
4. Double-click Axial depth of cut in the icon. 

Set this value to 3mm in the Edit Parameter dialog box and click OK.

Set Radial depth of cut to 3mm in the same way.
Other optional parameters can be set in the Options tab (lead-in and so on).
  When recess machining is active in Parallel Contour Rough Turning, Axial and Radial Depth of Cut must have suitable values to ensure a collision free toolpath. See Recommendations for more information.
  5. 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.
6. Select the Feeds and Speeds tab page to specify the feedrates and spindle speeds for the operation.

See Feeds and Speeds for Rough Turning for more information.
7. If you want to specify approach and retract motion for the operation, select the Macros tab page to specify the desired transition paths. 

Approach linking and retract linking motions are interruptible for this type of operation.

See Define Macros on a Lathe Operation for more information. 
  8. Check the validity of the operation by replaying the tool path.

9. Click OK to create the operation.
