Abstract
This paper deals with the development of a simulator applying mixed reality for the training of manual control milling machine operation and the evaluation of the performance. This system is mixed reality : tool and workpiece are virtual objects, and milling machine is an actual object. Therefore, in operation training, the simulator provides the same manipulative feeling as that of the actual machine to the trainee. The displacement sensors measuring the table position of the machine achieve the registration error between the tool and workpiece under 0.05 mm required for cutting simulation calculation. As the result of the operation with the simulator, it is confirmed that the simulator is effective with the high presence and safe operation environment.
