A CAD/CAM system by a personal computer for machining of a free formed surface has been developed by using an optical measuring system for 3-dimensional (3-D) object shapes. This CAD/CAM system is constructed by an NC milling machining attached with an XYZθ table and a personal computer. The optical measuring system is constructed by a CCD image sensor and a laser, and the 3-D objects shape can be measured by this system without any contact. The measured values are accurate about 80 μm and are converted to NC program by an automatic programming function. By this system, a 3-D object can be easily formed by the NC machining. So the authors have developed an optical profile NC machining used light sensor. It is attempted to machining for an abutment tooth and a doll's face with a free form surface for application in practice of this measuring and machining system.
