Contribution to the development of a digital twin based on CMM to support the inspection process

Abstract

Digital twin (DT) based on CMMs acting as a mirror between the physical and virtual measuring system and process. The inspection planning process performed on the virtual components of DT, and execution of measurement on the physical components. In this paper the measurement system with the DEA-IOTA-2203 was used as a physical twin, and a virtual machine, generated after modeling and configuring in PTC Creo software. Also, a simulation process was performed in order to check the collision and generate a measuring path for one example prismatic part. The information flow is unidirectional and flowing from the virtual to the physical inspection system based on CMM. In this way, a data format or a list of instructions for the physical machine and its movements per axes is provided. Virtual measurement system is developed for inspection of the standard types of tolerances and family of prismatic mechanical parts. The result of this paper is a new contribution to the development of the digital twin for CMM based on unidirectional information flow by.ncl (DMIS) file. The application of the results of DT development is especially pronounced when planning the inspection of prismatic parts with a large number of tolerances in industrial conditions.
