Many lathe simulators for acquiring skill to fabricate machine parts with a lathe have been already studied and developed. However, there is no simulator for training workpiece centering operation on a lathe, which is known as a high level skill required one. This paper deals with development of a simulator for the operation and its training effect. The simulator developed is composed of the working platform with the clamp-force-adjustment-device, an impulse hammer, a LCD monitor and a PC. A virtual workpiece clamped with a virtual chuck, a virtual test indicator and a virtual hammer are shown in the monitor. A trainee can check eccentricity of the workpiece by using the test indicator and reduce it by adjusting the clamp force and hammering. To confirm the effectiveness of the simulator, skill training examinations by trainees were carried out. As the result, it is found that the simulator improves the centering skill on actual machine operation. In addition, it is clarified that hammering skill is more difficult to learn than clamp-force-adjustment skill.
