Recording of machine tool operation plan for the generation of the CNC programs of a parametric CAD model

Abstract

This paper describes an automation method applied for the generation of CNC programs. In this method, an RPA software was used to record the actions required to generate a CNC code, which later were combined to reduce repetitive actions and to avoid human errors involved in the traditional flow followed to generate CNC programs. To achieve this, an interface containing a database that automatically provides the characteristics of the workpiece, tools and cutting parameters involved on each manufacturing process was also created. This method was successfully applied in the generation of the CNC programs required to the fabrication of a standard part in five different materials, two workpiece sizes and in 3 machining centers.
