自動ポリシングシステムにおける最適加工条件計算ソフトウェアの開発と加工条件のロバスト性の評価

抄録

The Polishing process is used as finishing process of many products with smooth surface. This process is generally conducted by skillful worker as manual process and the productivity is low and difficult to control. An automatic polishing system which consists of inexpensive tool and general purpose machine tool are developed. However, system operator has to have know-how and experience of the polishing process to decide the machining conditions. In this study, optimization algorithm for machining time and improvement of the surface roughness were established. Software for optimizing machining conditions of the system was developed and evaluated the robustness of calculated conditions by Taguchi method. Total machining time with calculated and optimized conditions could be shortened by 12% than conventional time in plane polishing. It is concluded from result that: (1) Developed software using the proposed algorithm of automatic polishing is effective to decide machining conditions without know-how and experience of the polishing process. (2) Full automatic polishing become possible by using the combination of developed system and the software.
