CNC automatic programming system for wire-EDM

This paper introduces a developed CAM system for wire-EDM to automatically select the sequencing of the wire path considering fixation stability. The system creates technological aspects based on geometry features. Many of the wire cutting techniques such as trim cut, correction, taper angle, threading & breaking points, and the standard radius are automatically added. For small area of polygons No-Core are automatically selected. Many files such as NC file, technology data file, and job file are automatically generated to control the cutting process. Also, the system simulates the cutting process for verifying check, minimizes errors, and to save machine time.
