Aspheric Surface NC Polishing Force-Position Decoupling Control Technology

摘要

Based on MTTSD (Magneto-rheological Torque Transmission Servo Devices) and force-position decoupling control technology, an aspheric surface NC polishing project is put forward. The aspheric surface polishing fundamental theory is researched. Under the condition of a constant material removal rate, a new aspheric surface polishing model is brought forward. In addition, under the condition of a constant material removal rate, this paper brought up a polishing force control model and a workpiece rotating speed control model, according to witch, force and rotating speed change with the coordinates of working points, and variation curves are drawn.
