ABSTRACT:
Precision control over the cutting force during robotic deburring and edge contouring is obtained by use of a "zero spring rate" driver. The driver consists of an air cylinder with a low friction piston. An accumulator is used in between an air supply line and the air cylinder such that the air pressure against the piston is constant. The driver is used to position or move a moving portion of an ultralow friction ball slide relative to a fixed portion of the ball slide. The arrangement avoids inaccuracies in a metal removal process which might otherwise be caused by robot path errors, part setup errors, and robot stepwise motion effects.
