Implementation of Augmented Reality (AR) for Training CNC TU-3A Milling Machine Operators

The development of technology and the demands of Industry 4.0 in the present era are causing transformations in training and learning methods. These include the practice of production processes in training for computer numerical control (CNC) machine operator TU3A. Despite the significant contribution, time constraints often hinder the effectiveness of training activities during practical sessions. Therefore, this research aimed to develop an Augmented Reality (AR) application to support practical training in production processes. The application was designed to provide instructions or basic training in operating the CNC machine TU-3A using the Unity platform and Vuforia Engine with the ground plane method. The design enabled the visualization of 3D model of the CNC machine TU-3A and data were obtained using quantitative methods. The results showed that the System Usability Scale (SUS) testing on AR CNC application, conducted through a questionnaire with 40 respondents, obtained a final SUS score of 71.13. This suggested that the AR CNC application was suitable for implementation as a supplementary medium for training/learning the fundamentals of operating the CNC machine TU-3A.
