This paper deals with a newly developed Numerically Controlled contouring Electric Discharge Machining (NC-CEDM) system. The proposed NC-CEDM is based on the shape standardization of the tool electrodes, and on the contouring control of the standard tool electrode by an automatic programming system, APSET2,which posesses a function of multi axis numerical control. The features of this machining system are (1) reducing time to machine the tool electrode, (2) increasing the accuracy and productivity of the tool by standardization, and (3) increasing the flexibility of the shape to be removed by the newly developed contouring control programming system. In this paper, the cross sectional profile of the tool electrodes are standardized to η (1≦η≦6) polygon, the corner of which has roundness. APSET 2 has the capability of controlling the tool position and attitude (rotation on the X-Y plane) along the contour. Experimentation with standard electrodes, APSET 2,and a fouraxis (X, Y, Z, U)-controlling NC electric discharge machine have demonstrated the realization of NC-CEDM.
