I'm trying to generate a toolpath to make a ring on my rotary 4th axis.
Roughing with a 1/8" bit is fine but the problem is that Its taking way too long to generate the finishing path for the bits that i use.
I have 2 bits that i want to use for finishing. 0.3mm endmill and a 1/8" veemill / v-bit.

Could someone help me get around this problem?
