General Mach Discussion / continuous motion and tangential cutting problem
« on: November 17, 2010, 12:30:44 PM »
hi
i use my cnc to cut with a knife with tangential motion on, and the feed rate is very fast compared to milling. what i notice is that the motion stops at each point, or code line, and then starts again, resulting in the machine shaking.
i wonder if anyone knows how to get continuous motion so that the axes move wit smooth flowing motion?
another problem i cannot solve is that for tangential knife cutting the knife will spin (A axis) in the material at what appears to be random times - it generally works fine, and only seems t do this once per cut-out shape.
many thanks.
