I am planning to simulate a hobbing operation to generate involute tooth profiles.
Eventually I hope to run it as a macro, but I seem to have got stuck even before I begin.
I have modelled a rack cutter, then modelled a gear blank, and proceeded to carry out the incremental shaping operations, by simple manual modelling.
However, after only a few iterations, although the majority of the rack cutter is overlapping the gear blank, the tip of the rack is tangential with the blank body which has already been cut on the first few iterations.
When I try to create a pocket, it forbids it because the cutting profile is tangential, i.e. locally at the rack tip.
Is there a way to bypass this alarm or reduce a tolerance or something?
Thanks
