Create a Sequential Turning Operation

task target This task illustrates how to create a Sequential 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 Sequential Turning icon . A Sequential Turning entity along with a default tool is added to the program. The dialog box appears directly at the List of Motions tab page . 
The first motion must be a Go motion to a point.
2. Select the Go icon . The dialog box for defining the first motion appears. 
   

In the Geometry tab:

  • Select a check representation in the dialog box then the desired check element in the 3D view.
  • Click OK to define the motion.
  3. Select the Go icon again to define the second motion.

In the Geometry tab:

  • Successively select the two check representations in the dialog box then the desired check elements in the 3D view.
  • Set the first and second check modes to To.
  • Set a offset on the first check element to 2mm.
  • Click OK to define the motion.

4. Select the Go icon again to define the next motion.

In the Geometry tab:

  • Select a check representation in the dialog box then the desired check element in the 3D view.
  • Set the check mode to Past.
  • Set a offset on the check element to 5mm.
  • Click OK to define the motion.
5. Select the Go InDirv icon . 

In the Geometry tab:

  • Select the drive direction in the dialog box then the desired linear element in the 3D view.
  • Select a check representation in the dialog box then the desired check element in the 3D view.
  • Set the check mode to To.
  • Click OK to define the motion.

6. Select the Follow icon . The check curve of the previous motion is used as drive curve. This drive element is highlighted in the 3D view.

In the Geometry tab:

  • Select a check representation in the dialog box then the desired check element in the 3D view.
  • Set the check mode to To.
  • Click OK to define the motion.

7.

Select the PP word icon , then specify a PP word in the dialog box that appears (DELAY/5, for example).
8. Select the Go Delta icon . 

In the Geometry tab:

  • Set the check mode to Line and distance.
  • Select the line representation in the dialog box then the desired linear element in the 3D view.
  • Enter a distance.
  • Click OK to define the motion.

Other optional parameters can be set in the Strategy tab page for each of the motions. 

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. Please refer to Edit the Tool of a Lathe Operation.
9. Select the Feeds and Speeds tab page to specify the feedrates and spindle speed for the operation. See Feeds and Speeds for Sequential Turning for more information.
10. Select the Macros tab page to specify the operation's transition paths (approach and retract motion, for example). See Define Macros on a Lathe Operation for an example. 
Before accepting the operation, you should check its validity by replaying the tool path.

11. Click OK to create the operation.
