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.

在本报告中，提出了一种具有柔顺可控性的新型台式数控机床，用于精加工小曲面金属模具。 Z 轴尖端附有一个小型球端磨具。控制系统由力反馈环、位置反馈环和位置前馈环组成。力反馈回路以约0.178N的分辨率控制抛光力。数控机床精细地去除模具上的小尖点，并高质量地精加工表面。数控机床的有效性和前景已通过实际精加工实验得到证实。
