Exploitation of the powerful capabilities of the parametric programming technique for maximizing the efficient operation of CNC machine tools

Abstract

Parametric programming is a high-level G-code language that is widely available in modern CNC controls. Its utilization in specific machining applications can provide significant benefits for industrial manufacturing units by maximizing the efficient operation of their CNC equipment. Parametric programming serves as a complementary tool to CAD/CAM systems and enables the development of concise and intelligent G-code programs with advanced capabilities. Its advantageous use is particularly justified in the invention of new canned cycles and the interpolation of complex curves that are of industrial interest. This paper focuses on three representative CNC machining cases. The first two cases involve the development of new cycles for pocket machining, specifically a trapezoid and a hexagonal pocket. The third case addresses the motion generation along an epicycloid curve, which is necessary for machining cycloidal discs, the primary components of cycloid drivers. The three cases presented effectively showcase the robust capabilities of parametric programming, highlighting its ability to directly extend programmable manufacturing features and eliminate reliance on CAD/CAM software. This not only reduces preparation time, which is the primary advantage offered by canned cycles, but also enhances the ease of CNC manipulation when dealing with complex curves.
