| Research Abstract |
In this report, a novel desktop NC machine tool with compliance controllability is presented for finishing a metallic mold with small curved surface. A small ball-end abrasive tool is attached to the tip of z-axis. The control system is composed of a force feedback loop, a position feedback loop and a position feedforward loop. The force feedback loop controls the polishing force with a resolution of about 0.178 N. The NC machine tool delicately removes small cusps on a mold, and finishes the surface with high quality. The effectiveness and the promise of the NC machine tool have been confirmed through actual finishing experiments.
