抄録

Students in many universities, technical colleges, and technical high schools are practicing their cutting skills using general-purpose machining tools. However, there may be insufficient guidance due to the lack of the number of instructors and a limitation on the number of general-purpose machining tools that they can use. In this research, we propose a system to support the learning of cutting skills using a virtual reality head-mounted display. Preparing students to use machining tools require many training sessions, especially for cutting using a general-purpose lathe. A user can experience three types of content: drawing, tools, and the general-purpose lathe. This learning system was provided to seventeen students, and we conducted a questionnaire on its ease of understanding, appearance, enjoyability, intuitiveness, and operability. Resultantly, enjoyability and intuitiveness were highly evaluated. The results suggest that our proposed system can be used as a learning method. To improve the operability of the VR system, we can make use of specialized controllers or additional force presentation devices.
