When making a precision machine part with a manual machine tool, knowledge of machining sequence and skill of handwheel manipulation are indispensable. Although many simulators using virtual environment have been developed for acquiring the knowledge and skill so far, there are few ones aiming to acquire both of them at the same time. In this paper, the authors aim to confirm effectiveness of manual milling machine simulator to allow the trainee to acquire both of them. The simulator is a mix reality system displaying a virtual tool and virtual workpiece on an actual machine by using ARToolKit. Trainees can get information about machining sequence and evaluation of handwheel manipulation in their operation with the simulator. To confirm the effectiveness of the simulator, subjects trained by the simulator are compared with subjects learning by a textbook. As the result of the experiment, the subjects trained with the simulator demonstrated shorter operation time and less mistakes than done with the textbook, the feed speed of the subjects trained by the simulator is closer ideal feed speed than that achieve by the textbook. In conclusion, the simulator can provide a trainee with effective environment for acquisition of knowledge of machining sequence and skill of handwheel manipulation.
