Abstract

In this paper, the cutting effect of Al-alloy using a single diamond turning machining is applied to make on aerospace spherical mirror. The ultra precision cutting has been done in the thermal vacuum chamber and the experimental tryout was minimized using the optimum processing conditions which were determined design of experiments. In this study, we considered three influenced factors on the surface roughness such as cutting speed, feed rate and depth of cut. The purpose of this research is to find the optimum machining conditions for cutting reflector apply the SPDTM technique to the manufacturing of ultra precision optical components of Al-alloy spherical reflector. The cutting force and surface roughness are measured according to each cutting conditions. We achieved the spherical mirror in the 300mm diameter with the surface roughness and the shape accuracy. We also show that the values can be applied to make the Al-alloy spherical reflector using diamond turning machine to perform cutting processing. the abstract two lines below author names and addresses. The abstract summarizes key findings in the paper.
