Machine tool operations such as small-diameter-deep-hole drilling and boring are well known as skilled tasks because of low stiffness of the cutting tools. Artificial reality technique is useful to develop the simulator for skill training of the machine tool operations. In the present paper, the simulation of the boring operation with a lathe has been investigated. Since the size, shape and tactile feeling of the tool feed handle of the lathe are important in the skill training, an actual handle should be used in the simulation. In addition, operator's head movement during the operation should be taken into consideration. So, the authors have adopted the mixed reality technique to realize the simulator. Simplified dynamical and geometrical models have been introduced and their parameters have been identified by an optimization method from experimental data of the actual lathe operation.
