  1. Activate the Manufacturing Program and click Trochoid Milling in the Prismatic Machining Operations toolbar.

    A Trochoid Milling entity is added to the Manufacturing Program. The Trochoid Milling dialog box opens directly at the Geometry tab .

    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. Still in the Geometry tab.

    See Selecting Geometry

    1. Click the red bottom in the icon, then select the desired bottom element in the authoring window.
    2. Click the red flank in the icon, then select the desired guiding element in the authoring window.
    3. Right-click Start to set this condition to Out. Click the corresponding relimiting element in the icon, then select the desired start element in the authoring window.
    4. Right-click Stop to set this condition to Out.. Click the corresponding relimiting element in the icon, then select the desired stop element in the authoring 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.

  3. Select the Strategy tab to set the Machining Parameters, Stepover Parameters, and User Parameters.

  4. Go to the Tool tab to select a tool.

    See Specifying a Tool Element in a Machining Operation

  5. Select the Feeds and Speeds tab to specify the feedrates and spindle speed parameters for the operation.

  6. Select the Macro tab to add approach and retract macros to the operation, if required.

  7. Click Tool Path Replay to check the validity of the operation.

    See Replaying the Tool Path


    • The tool path is computed.
    • A progress indicator is displayed.
    • You can cancel the tool path computation at any moment before 100% completion.

  8. Click OK to create the operation.

    The trochoidal motion is generated on the whole tool path while respecting:


    • the Direction of cut (climb or conventional)
    • the Engagement (A) of the trochoidal motion, in particular with the curves
    • the Trochoid diameter (B).
