In this study, the replica of the metal processing surface was manufactured using the transparent silicone. Set for the new method for measurement using the transparence replica, it can get various characteristics by a processing method. The result was summarized in the following. The characteristic various patterns were provided by passing light in a transparence replica. Those patterns were able to be classified in a point pattern, a circle pattern, an oval pattern, four patterns of the diffraction pattern. It is possible that these patterns estimate the shape of the reflection plane, namely shape and processing method of the machined surface. The surface roughness by the diffraction was equal to the maximum height roughness by the tracer In the last paper, the empirical formula that showed the biggest height coarseness and the relations of the radius of gyration was provided in a circulation pattern and an oval pattern. This report makes a specimen of the end mill processing that is used a lot as a general processing method and shows the reliability as the measurement system of the assay by the transparence replica method.
