Hi, I am new to FeatureCAM and I need to use mill turn to mill a simple open ended slot across the front of a piece of 25mm dia bar. The slot needs to be 8mm wide and 20mm deep, so what kind of approach should I take regarding the kind of feature to select.
The machine is a Doosan Lynx 220 Y axis.

Also, The manual ISO code for this feature would be good.

Thanks.

You would want to either do a "Slot" from dimensions or a "Groove" from a curve.
Good Luck~!:cheers:

Another method if you use an 8mm diameter cutter.
