Abstract
A grinder robot having a grinder can be operated by both of a force control and a position control to grind a workpiece surface quickly and acccurately. When the grinder has not reached a target grinding point position to finish grindings, force loop drive control means are selected to drive the grinder in order to grind a work by a force control. After a grinding point ground by the grinder has reached the target position, then, position drive control means are selected to drive the grinder by a position control in order to execute precise grindings. A grinding amount in every grinding in a force control area is relatively large and a grinding speed in every grinding in a position control area is relatively fast. As a result, a workpiece can be ground quickly and accurately by the grinder robot.
