Abstract

Summary

The study presents the development of a cost-effective CAD/CAM system for metal moulds by use of a 16-bit personal computer. In the personal CAD/CAM system named MCSYS, metal moulds are defined by the operations of addition and subtraction of shape elements. Shape elements consist of basic elements such as prism, pyramid and sphere, plane, rotational body and surface elements including curved surface. The internal expression of shape elements in the computer is based on the wire model, which is a set of cross-sectional curves of the shape element. Each cross-sectional curve is approximated by the combination of lines and circular arcs. The wire model representation facilitates the generation of tool paths. NC instructions generated are directly transferred to a machining center through the communication line RS-232C. As a result, it becomes apparent that MCSYS has potential of producing metal moulds economically.
