Example 1: Turning - Groove Finishing - use an expression to specify the Stepover parameter value

Define the value of the Stepover parameter so that it equals 1.5 of the tool's Corner radius parameter.

1. In the Groove Finishing dialog, on the Passes tab, next to the Stepover box, click the More menu and select Edit Expression from the context menu.

   The Stepover dialog opens where you can edit an expression for this parameter.

2. In the Search box, type corner to find the name of the Corner radius parameter.

   The search returns tool_cornerRadius.

3. In the box at the top of the dialog, type: 1.5*tool_cornerRadius.

   Tip: As you are typing the parameter name, the list of parameter names starting with the entered string expands. You can click the required name on the list to add it to the expression.

   

   The Value line shows the value of the Stepover parameter calculated based on the expression.

   Tip: You can also click the More icon, and in the Edit Expression dialog, select the auto_threadPitch from the list.
