Design and Development of a G-Code Generator for CNC Machine Tools Based on Augmented Reality (AR)

Abstract

Modern manufacturing systems rely on the utilization of Computer Numerical Control (CNC) for the manufacturing of products and components. By extension, engineers must be capable of programming machine tools (through G-code) in order to achieve the desired results. However, this process is time consuming and requires highly skilled and trained personnel. On the other hand, under the Industry 4.0 framework, several cutting-edge digital technologies have been developed in an attempt to improve user perception, such as Extended Reality (XR), which encapsulates Augmented Reality (AR), Mixed Reality (MR), and Virtual Reality (VR). Furthermore, the above-mentioned technologies enable engineers to extend Human-Machine Interaction (HMI) into new dimensions. Therefore, in this research work the design and development of a framework for facilitating engineers during the generation G-code script for machining operations based on the utilization of AR is presented. The MR functionalities will facilitate develop a better perception of the machining processes, as well as support the generation of virtual instructions for shop-floor operators. Further to that, advanced communication functionalities are provisioned based on Cloud technologies, in order to automate the transmission of G-code scripts/instructions to the machine tools.
