Simulation of the metal spinning process by multi-pass path using AutoCAD/Visual LISP

Metal spinning on NC machine-tools is a complex flexible manufacturing method with high efficiency for small and single series of parts. The algorithms which describe the roller trajectory during the process are complicated and hard to understand. This paper presents an application developed under Visual LISP environment which simulates the metal spinning process by multi-pass path for rotational sheet parts, cylinders and cones. The simulation is based on some algorithms created by the authors in previous research and is a convenient tool for professionals to test the manufacturing process before the real production. The application is user-friendly, simple and intuitive.
