Automatic Generation System for Making NC Punch Press Programs using Pattern Recognition Technique

Abstract

An automatic program generation system for NC punch press machine is proposed. NC programs to control machine tools can be generated automatically by the system according to the data described in the design drawing of final products.
In this system, silhouette decomposition procedure which is one of pattern recognition techniques is employed to recognize the drawing. The procedure is applied to decompose a complex shaped hole in the design drawing into punch primitives, where the shaped hole and the punch primitives correspond to the overlapped silhouette and the discrete components of it, respectively.
The outline of the developed silhouette decomposition procedure and automatic program generation system is given.
