https://forums.autodesk.com/t5/hsm-forum/simultaneous-4th-axis-machining-inventor-cam/m-p/11362516#M1547 <P>I have a HAAS UMC750 5 axis mill. In this mill the machining envelope is not centered on the C axis plattor. The capa in X, Y is 30"x20" offset about 6" to the -x side of the C axis. I have a part that will not fit in the envelope centered on the plattor. Its slightly too large in the +X and +-Y directions. However, I can reach all extents of the external profile if I rotate the C axis plattor and operate in the -X side as the envelope is offset to that side. What I need to know is there a way to write a toolpath in Inventor CAM that will rotate about the C axis while machining the contour by moving the XY axis&nbsp; in the available -X area. Almost like a wrapped toolpath but my part is not round. This seems totally possible to me, I just cant figure out how to do it.</P><P>Images below. This is the trunion and the plattor assembly in the machine. The square box is the available machining envelope. Setup shown with and without my part on plattor. Anything helps.
