A Study on CAD interfaced CAPP System for Turning Operation (II) : Automatic Setup Planning

선삭공정에서 CAD 인터페이스된 자동공정계획시스템개발에 관한 연구(II) : 작업준비계획의 자동화

This paper presents an automatic setup planning system for turning operation of symmetric rotational parts. The proposed setup planning system determines workpiece holding method, number of setup, clamping surface, and workpiece holding device by using design data, part description database and part feature recognition information. The workpiece holding method is based on functional name and length/diameter ratio of the given part, and number of setup is determined by part profile type and its technological constraints. Clamping surface and workpiece holding device are determined by using information about the results of workpiece holding method and number of setup, and capacity of workpiece holding devices. A case study is performed to show the performance of the proposed system.
