An optical profile NC machining for a free formed surface has been developed by using an automatic non-contact measuring system of 3-dimensional model shapes and an NC milling machine. The principle of this system and the results of machining a free formed doll's face and an abutment tooth with accuracy of 80 μm were reported in the 1st report. In this study, it is attempted to apply this system to a dental CAD/CAM system developed by authors to machine a crown. Then, it was done to machine an abutment tooth and inside of the crown with free formed surface by this system. As a result, it could machine the whole shape of the abutment tooth with an under-cutting side. Consequently, it is verified that this system is applicable to the dental CAD/CAM system.
