OS1811 Study on Measurement Accuracy of the End Mill Processing Surface Roughness using Light Transmission-Style Transparent Replica Method

In this study, the replica of the metal processing surface was produced using the transparent silicone. The new measuring method which examined the transmission image was proposed with a scattering of the spot light in the replica. 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 circulation 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. 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.
