| Abstract: | Precision processing is performed for martensitic stainless steel SUS440C by loose abrasive machining technique. The processing parameters of lapping such as rotating speed of pad, load and processing time are optimized by Taguchi method. The surface roughness of workpiece after lapping with the optimized parameters is Ra 7nm. The polyurethane pad and SiO2 particles are used in polishing. The surface roughness of workpiece after polishing is Ra 8nm, and a mirror surface is obtained. |
