Trying to figure out what's going on with this one... I'm working on some small knobs for cabinetry and trying to finish the OD with a button tool.
It wants to drag straight through several stepped fillets in a straight line, violating the part:
Notice that it only does this on the larger fillets at the back, not the smaller ones at the front.
If I switch from a 3mm button to 2mm button, it does the same thing but with the other set of fillets instead, so I think it's something to do with the relationship between tool radius and fillet radius.:
In both cases if I set 0.1mm Stock to Leave, it machines the correct profile. That's fine in this case as my student won't notice a 0.1mm oversize knob, but I'd like to resolve the issue for next time.
