I realized today that I think I have the parts that I need to try CNC mirror figuring. I made a Bath interferometer, so I can generate an error map of the mirror. At work here we have a Hurco CNC mill. The challenge is to program the CNC mill based on the error map. I've heard of G-code, which we've used to determine the path that a 3D printer should take. The Hurco has software that will determine the path of the tool based on the part design. So we have software that is close to what I want, but not exactly. Rather than control the Z-axis of the mill, we need to tell the mill to pass over a high spot more often. It would also be good to incorporate the profile of the polishing tool. I imagine using a petal shaped sub-diameter tool to smooth out the edges of tool's path.
Has anyone here tried to do this? Is there software that exists that we can use to convert the error map to program the CNC mill?
