SYSTEM AND METHOD FOR COMPENSATING FOR COMPLIANCE OF A HEXAPOD POSITIONING DEVICE

摘要

A system and method for compensating for compliance distortions in a positioning device, such as a hexapod machining center, is disclosed. The position device has a movable platform mounted on a plurality of actuators at a plurality of pivot locations. The method comprises the steps of: calculating compliance information of the positioning device; compensating actuator movement commands according to the collected compliance information; and moving the positioning device actuators according to the compensated movement commands.
