Now I have question from customer about turning of eccentric diameter of camshaft.

Machine is OKUMA Multus B750.

Please, if someone have experience with this type of cutting, could you can to share it?


My point of view is:

  1. I make Variable Contour with Helical Cut Pattern with small step, calculated according length of cutting area and recommended feed per rotation.
  2. On machine start this program with turning tool instead milling tool.
  3. Integrated simulation work fine, but when start real cutting machine stop at first line with G01.


In this situation I have not any spindle rotation that, from my point of view, stop cutting move.

Do you have info about specific OKUMA G or M code that will force cutting move in this situation?
