If i want to do a front operation, and then physically flip the part to do a 2nd operation on the back, do I do this in one "turning" project? In milling, I would create two coordinate systems; one for from and back, to achieve this. I was not able to get the correct toolpath doing this for turning, because the tool would face the wrong way despite the 2nd coordinate system being oriented properly. Should I create two turning operations instead of two MAC's ? Creating two turning projects mean I have to create two machine configurations and to import all my tools, however. So far I have not been inclined to do that as I have thought it inefficient to do that.
