Dear all,
I am facing the following problem with a Fanuc 6Mb control in combination with UGS NX CAM 7.5.
NX generates a 3d circular(helical?) path during the beginning of a cavity mill operation (to smoothly enter the blank). The post processor then converts this tool path to a G03 circular interpolation code for the Fanuc 6M control.
The problem is that the Fanuc control can not handle this command. It can handle in plane (2d) circular interpolation, but not combined with a 3rd axis. If have added an example below:
This goes wrong: G03 X100. Y54. Z38. I3.799 J2.412 K-1.206 F200.
This works: G03 X100. Y54. I3.799 J2.412 F200.
Maybe someone knows a way to adapat the control (via a parameter?) such that this will be possible to do this on the machine? A second option would be to let NX generate a toolpath which is not 3D circular. I cann't find a way to do this in NX. Can someone help me with this?
Thanks in advance and best regards,
W.Lamers
