A Nonrevolving Solid Turning System utilizing Turning NC Language

Abstract

The machining of a nonrevolving solid has been carried out by means of a copying lathe. However, this method is limited to simple forms and low efficiency due to limitations in the ability to follow the stylus movements on the model. To improve efficiency and diversity of non revolution machining, a lathe incorporating an electro-hydroulic servo system for positioning the cutting tool in phase with the rotation of the workpiece has been developed. However, this system is very expensive. In the present investigation, an automatic programming system to machine a nonrevolving solid using regular NC lathe and NC language without other adoptations was developed. This system uses the nonfixed screw cycle to machine a nonrevolving solid. A wide variety of outlines can theoretically be machined with this system, but more work is necessary to develop the practical potential.
