Groove insert-holders support Groove inserts and Trigon inserts. This document describes the capabilities of the Groove insert-holder with a Trigon insert.
An Internal, Frontal or External Groove insert-holder with a Trigon insert can be used in the following operations:
All strategies supported by Groove insert-holder with Groove insert are also supported by Groove insert-holder with Trigon insert.
In addition the following capabilities are available with the Groove insert-holder & Trigon insert configuration:
Collision avoidance with the part.
Update of computed stock with such tools.
Material removal simulation in video is supported with such tools.
Some limitations exist due to an approximation of the tool insert in the algorithm.
Trigon insert bottom angle is always 10 degrees.
A shift exists at the insert bottom, which is taken into account in the computation.
This is particularly noticeable when machining low slope geometry shapes.
Undercuts parts are not machined in groove finishing.
The corresponding flank angles are set to 0 degrees instead of 20 degrees to avoid any risk of collision.
20 degrees are added from the real edge of the trigon insert when considering the gouging safety angle in the toolpath computation.
