This paper aims to efficient teaching of lathe training. As a way of doing this, attach a small-sized camera to the instructor and display instructor’s perspective on a large monitor. Students receive explanations while watching the monitor and the actual lathe. By reflecting the instructor’s perspective on the monitor, students are not limited to the area around the instructor’s lathe, and students can receive explanations in the same direction as the instructor. In addition, students can understand where the instructor is explaining or where the instructor is paying attention to the processing by looking at the monitor.
