Simulations of machining based on STEP-NC

Abstract

This paper presents the possibilities of application of a new method of programming based on STEP-NC standard, which was developed as an alternative to the G code. This paper discusses the possibilities of application in the field of simulation and verification of the program before machining and machining on the available machines. The paper shows the possible methodology for simulation and verification of programs based on the STEP-NC using IDEF0 diagrams, as well as links between softwares STEP-NC Machine, CAD/CAM systems and CNC simulator. The presented methodology is verified by machining of the test workpiece NAS979, based on STEP-NC program.
