I have G-code generated for a 5 axis CNC machine, with a rotating and tilting table. I would like to run this code on my robotic arm and therefore thought about converting it to a rotating and tilting head movement. For better understanding, I will attach an image. This should be possible (right?), but I do not get the mathematics behind it. My aim is then to write a small script to convert the G-code.

  • $\begingroup$ I agree it's definitely possible, but probably not simple. IKFast is a tool for automatically calculating inverse kinematics. That might work if you don't want to do the math manually. If you want to try the math manually, I'd start by writing out the coordinate frames of each joint. Denavit–Hartenberg parameters are a standard way to do that. $\endgroup$
