I’ve been doing lots of 2.5 axis CNC carving but recently added a 4th axis, which is widening the possibilities but also the learning curve.
In short I would like to be able to machine below the rotational axis when using the 4th axis, here is an example of a spoon to illustrate. I understand some of the softwares can do it and increasingly I’m being asked to work with sort of sculptural forms which curve either side of the rotational axis and sometimes have voids as well. At the moment i’m not sure how to do do this but i’m sure it can be done.
My question is which CAM software and strategies will help me understand and work out methods to mill out forms like this (not spoons).
Thanks
