I am trying to mill an ID radius as seen in pics.
I have machined a funnel using an older version of Gibbs in the past.
I'm remembering swept side with the shape in another workgroup extruded,
I think.
None of that is working currently.
Gibbs 7.3.1 2D only. XY center of part in a chuck on table. Wanted to rough with a 3/8
Flat endmill and finish with 3/8 ball. Aluminum.
You can use the Spiral Plugin driven by the Geometry. You need to define the Profile in the X-Y Plane using the line and arc as if you were going to create a revolved surface or solid, then select the geometry and run the plugin. I'm not sure what version the Plugin was introduced, but it works great.
