Development of the CAM system for 5-axis automatic shoe roughing

5축 러핑 전용 CAM 시스템 개발

A roughing process is one of the most important and indispensable shoe manufacturing processes of various types of shoes. This basic process to rough the upper of the shoe is studied to improve the productivity and to reduce the processing time. In this study, the CAM system for shoe roughing is developed. The B-spline surface generated by the developed CAM system ignores the small inclinations of the real roughing surface because the developed roughing tool has potential to rough the roughing surface of the shoe properly. The roughing tool roughs the roughing surface using its side along the generated tool paths. The generated NC codes were applied to 5-axis polishing machine for the test. Experimental results show good evaluation result. The upper of the shoe is roughed properly along the roughing path line and the roughing surface was good to cement the outsole of the shoe.
