The answer is probably "maybe" I don't think that doing what you describe makes any sense unless you can also change the angle of the tool axis. If you are talking about changing the tool axis then it becomes a normal 4/5 axis kinematics. I guess with a tilting-head mill there is no reason that the angular axes used by kinematics need to actually be motorised. The AB angles could be inputs to HAL set to match the physical angles manually set by the operator. There is a 5axiskins in src/emc/kinematics that might already do what you are describing under the situation described above. -- atp If you can't fix it, you don't own it. http://www.ifixit.com/Manifesto ------------------------------------------------------------------------------ Get 100% visibility into Java/.NET code with AppDynamics Lite It's a free troubleshooting tool designed for production Get down to code-level detail for bottlenecks, with <2% overhead.
