This study aims to develop a machining system that uses a haptic device as a new operation interface to enable even beginners to operate a machine tools easily and safely. The haptic device is important because it can provide the user with sensations of physical force, such as shocks or vibrations, in the virtual space. These sensations of force function to guide the operator to suitable operation by limiting tool movement. In this study, a system is developed to teach, using the haptic device, the tool movements in machining shapes in a virtual space. The tool movement that is taught is output as the movement of machine tool, and the actual machining is performed. In our study, the usefulness of developed system is confirmed through machining experiments.
