The default selected tool for turning will have:
Lathe – groove/cutoff type.
An insert Width of at least Groove Width – Finish Z Allowance
The shortest depth that will cut to the bottom of the groove.
The proper orientation for the type of cut. See Groove tool orientations for more information.
For ID grooves the Length of the groove is checked against the length of the holder to ensure that it will extend far enough into the part.
For face grooves cut in the positive direction, a tool is selected so that the inside edge of the groove is between the Min plunge diameter and Max plunge diamete.r If the groove is being cut in the negative direction, the outside edge of the groove must be between these two values.
Currently tip radius, and insert grade are not taken into account.
