In the present study, the shape of an object is first obtained from photographic images using the photometric stereo method, and then the target object is created using material that gives an artificial impression of wood. We found through experimentation that the output gradient on the surface of the target object is limited to 67°. Moreover, there is a fault that a lustrous object cannot be reproduced by a general photometric stereo method. Then, to overcome the fault, we propose using a Gaussian filter. The results showed that the maximum error margin of the shape of the reproduced object could be adjusted from 8.3 to 3.3%. At the end, the feature that the normal vector in respect is obtained by using the photometric stereo method is made the best use of, and we propose a new method to obtain cutting location (CL) data for ball-end milling using the normal vector of the object geometries generated by the photometric stereo method. As a result, the tool path was quickly and easily derived, without the use of CAD data.
