Previously, selecting the start extension as circular would extend the toolpath only in the circular way.

Starting from Creo 9.0, you can choose whether to extend the toolpath in a circular or tangential way after you specify the start and end extension values in the Tool Motions dialog box. It brings full flexibility in choosing either circular or tangential extensions in turning.

For more information, follow this link.

User Interface:

  • In a manufacturing assembly, click Turn and select a Profile, Area, or Groove turning sequence command.
  • Under Tool Motions, select a turning cut, and then select the reference. The Turning Cut dialog box opens.
  • Under Options, select the Offset Cut check box.
  • Select Circular extension or Tangential Extension for the start and end.
