Abstract:
A work piece processing device includes a tool device, a work piece holder and a servo-elastic actuator system having simultaneous precision force and position control that moves one of the tool device and the work piece holder to the other of the tool device and work piece holder. The servo-actuator system including a servo-actuator, a compliance elastic member and a weight compensation elastic member disposed in a force transmission path with the compliance elastic member and the weight compensation elastic member disposed with respect to each other so that a spring force exerted by the weight compensation elastic member is opposed to a spring force exerted by the compliance elastic member.
