2024 06 25 - Mastercam - Unified and Swarf - Shaft Keyslot Machining

Using Mastercam Unified set to Automatic mode, and adjusting the boundary control to create a good toolpath on this irregular shaped key slot on a shaft.
This one has some odd Tool Axis Control things to address to force the tool to behave the way we want it to while locking it to 4 axis.
Also includes a Swarf multiaxis toolpath to finish the walls.

Thanks👍👍

thank you very much!!!😘. I have one question related to 5 axis and rest milling/rest roughing/ 5 axis ops' stock awareness. Say you have the part after roughing and you want to use an automatic way of rest machining it. Something like a rest milling on a 3 axis op where you select the whole part not just individual surfaces. Also assuming the part has small undercut and you are not able to use a 3 axis operation with holder colision checking/trim to avoid gouge, active, because this being a 3 axis op will not see the undercuts. As an example take 5 axis deburr toolpath but as a 5 axis rest milling. Maybe Triangle mesh?

All 5 axis toolpaths are stock aware, so what you may want to do is just a normal finishing op, but turn on roughing/multi passes. It'll trim it back to the stock. If you have an example, I'd be happy to make a video on it. Send it over to [e-mail].

@@VectorMfg thank you for your reply. I don't have any examples I was just curious how it can be done. Thanks 👍
