Programming of machine tools and robots for machining using STEP-NC in the era of Industry 4.0

Abstract

This paper presents a method for applying the ISO 10303 238 (AP 238) standard for programming CNC machine tools and robots for machining operations. The method encompasses programming, simulation, and machining by machine tools and industrial robots as part of current and future research at the University of Belgrade Faculty of Mechanical Engineering. Application and validation of methodology for programming according to STEP-NC protocol are performed using available CNC machine tools and industrial robots, with the following tools: (a) commercial CAD/CAM software, (b) STEP-NC Machine software with configured virtual machine tools and virtual robots, as well as (c) developed translators for generation of G-code and/or robotic programming language. STEP-NC provides new opportunities to support high-level information from design to CNC controller. This implies further evolution of the CNC system they will act using STEP-NC standards as an interface between CAD and CNC in the era of Industry 4.0.
