The front and back angles are used by Axis to display the tool in the back plot. Run the Axis lathe sim and load each tool 1-9 to see how they change. JT On 6/24/2015 4:35 PM, Tom Easterday wrote: Hmm, are these angles used by Axis to display the correct geometry for the tool tip in the

If you run the Axis lathe sim you can look at the tools in the tool table there is one defined for each orientation. The angles are for display only. The orientation and radius are used to define the control point. The control point and radius is used by G41/42 cutter compensation.

Hmm, are these angles used by Axis to display the correct geometry for the tool tip in the backplot? If so, that doesn’t seem to be working (at least in 2.7.0~pre6). I have the Orientation and the Front/Back Angles set (angles, perhaps incorrectly) but Axis shows the tool pointing up from
