Abstract

In the recent years the computer-numerical controlled cutting process such as a plasma arc cutting and a laser cutting is widely applied to reduce the time and cost expense for generating NC part program of the parts to be cut. In the present study, a CAD system(C-CAD) was developed to generate automatically the NC part programs with CLDAT(Cutter Location Data)for the CNC plasma arc cutting system. The NC part programs are composed of the 2-dimensional drawing of the parts to be cut and the technological data. The shape data of the parts drawn in the Auto-CAD can be also used in the C-CAD, since the data file generated by the C-CAD is compatible with that by the Auto-CAD. In order to check its applicability, the C-CAD and CAM system were applied to cut the parts, and which showed the satisfactory results.
