task targetCreate a 4-Axis Pocketing Operation

task target This task shows how to insert a 4-axis Pocketing operation in the program. 

To create the operation you must define:

  • the tool that will be used
pre-requisites Open the 4XPocket.CATProduct document, then select Machining > Prismatic Machining from the Start menu. Make the Manufacturing Program current in the specification tree.
scenario 1. Select 4-axis Pocketing .

A 4-axis Pocketing entity along with a default tool is added to the program.

The 4-axis Pocketing 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 bottom and flanks of the icon are colored red indicating that this geometry is required for defining the pocket. All other pocket geometry is optional.
Make sure that the Pocketing style is set to Open Pocket.
2. Right-click the red Bottom in the icon and select Contour Detection from the contextual menu.

Click the red Bottom then select the desired pocket bottom in the 3D window.

The pocket boundary is automatically deduced thanks to the Contour Detection setting. This is indicated by the highlighted Drive elements.

The bottom and flanks of the icon are now colored green indicating that this geometry is now defined.
3. Click the Top element in the icon then select the desired top element in the 3D window.
4. Set the following offsets:
  • 1.5mm on hard boundary
  • 0.25mm on bottom.
5. Select the Strategy tab page and choose the desired tool path style:
  • Inward helical
  • Outward helical
  • Back and forth
  • Part offset One-way
  • Part offset Zig-zag.

You can then use the tab pages to set parameters for:
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.

6. Select the Feeds and Speeds tab page to specify the feedrates and spindle speeds for the operation.
7. Select the Macros tab page to specify the operation's transition paths (approach and retract motion, for example).
  • In the Macro Management frame, right-click the Approach line and select the Activate contextual command.
  • In the Current Macro Toolbox frame, select the Axial mode. A sensitive icon representing this approach motion is displayed.
  • Double click the distance parameter in the sensitive icon and enter the desired value in the pop-up dialog box.

  • Repeat this procedure to specify the Retract motion.
See Define Macros of an Operation for another example of specifying transition paths on a machining operation.
  8. Before accepting the operation, check its validity by replaying the tool path.

9. Click OK to create the operation.
