We're running a KR60L30/KRC2/KSS 5.4.14 with a rotary table using Powermill to generate CAM toolpaths for carving foam and wood. We've been experimenting a bit with velocity and acceleration variables and now trying to understand better the relationship between APO.CVEL and ADVANCE. Specifically, I'm wondering how much smoothing ADVANCE cause beyond the next point.
If ADVANCE is set to 1, the robot will load the next point to be run which CVEL will use to round the path past the point it is currently approaching. Will the robot use subsequent points beyond the next point to calculate the smoothing or only the next point? What is the advantage of using higher values for ADVANCE?
I've noticed that when I set CVEL to 100% and ADVANCE to 5, we get smooth fast movements, but loss of fidelity in the carving: the surface of the part doesn't look to be as smooth as it could be. CVEL values below 40% cause very jerky motions in the spindle as well as the table: too little smoothing.
For example, if I set CVEL to 40 and ADVANCE to 1, should that generate moves with greater fidelity to the CAD model than if I set those values to 40 and 5? Will more ADVANCE generate greater path smoothing?
Thanks
