Helical drilling using polar coordinate interpolation
The lathe in question is Mori Seiki SL-303 with MSG-501 controller:
We're trying to do helical drilling on the face of the workpiece using polar coordinate interpolation but it keeps causing "illegal axis plane"-alarm no matter what we do. Our program is something like this:
The plane selection G17/G18/G19 doesn't have any effect on the outcome... is this simply a feature of the contoller that you can not move more than 2 axis at the same time while polar interpolating (can this be changed from machine parameters) or what are we doing wrong?
