Hi Tom,
I have not used my rotary axis much for true 4th axis cutting, mostly indexing. But trying to cut a slot in a cylinder here today and having a bit of trouble. Doesnt seem like feed rates are working properly for me. Im trying to cut at 60 IPM on a 1.7 dia cylinder, 1.44 dia at tip of tool. My cam software is outputting feedrate at around 4500 degrees/min which seems right, but seems like its going way faster then this. Seems to be going to the maximum I have specified in the trajectory planner.
The slot has a 90 degree turn, so part of it is moving only in X axis, and part of it is only in A axis, and you can tell the feed per tooth on the surface finish is way higher in the rotary moves. Any ideas? Thanks.
Mark
