Create a Trochoid Milling Operation

This task shows how to insert a Trochoid Milling operation in the program.

To create the operation you must define:

  • the tool that will be used
Open your CATPart document, then select the desired Machining workbench from the Start menu. Make the Manufacturing Program current in the specification tree. 
1. Select Trochoid Milling .

The Trochoid Milling dialog box appears directly at the Geometry tab page . This page includes a sensitive icon to help you specify the geometry to be machined.
The part bottom and flank in the icon are colored red indicating that this geometry is required for defining the operation. All other geometry is optional.
2. Click red bottom in the icon, then select the desired bottom element in the 3D window.
3. Click red flank in the icon, then select the desired guiding element in the 3D window.
4. Right-click Start to set this condition to Out.

Click corresponding relimiting element in the icon, then select the desired start element in the 3D window.
5. Right-click Stop to set this condition to Out.

Click corresponding relimiting element in the icon, then select the desired stop element in the 3D window.
The bottom, guide and limit elements of the icon are now colored green indicating that this geometry is now defined. These are also indicated on the part.
6. Select the Strategy tab page .

You can then use the tabs to set parameters for:
7. An end-mill 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 another end mill tool. 

This is described in Edit the Tool of an Operation.
8. Select the Feeds and Speeds tab page to specify the feedrates and spindle speeds for the operation.
  9.

If needed, add approach and retract macros to the operation in the Macros tab page .

For more information please refer to Define Macros of a Milling Operation.
10. Check the validity of the operation by replaying the tool path.
11. Click OK to create the operation.
