Re: 2021 ST20Y Threadmilling a Bolt circle on the face
I was curious so I just tried it. Very easy to set up in Fusion. I used the Harvey Hole Making and Threading library to select the tool, took me a bit to find the correct tool from the list. For the operation choose Drilling, then from the Cycle tab, choose Thread Mill. Was able to generate the tool path in a few minutes. The simulation looks good.
Now putting this into actual practice on the machine might be a bit more tricky, but Fusion has pretty good post processors for Haas machines. I guess I would start out with the recommended feeds and speeds and adjust from there as needed. Buying a few extra thread mills might be a good idea. Air cuts to start with would be a good plan.
