Paper Abstract

When using the single-point diamond-turning (SPDT) technique to produce oxygen-free high-conductance (OFHC) copper reflector, it is found that surface quality, in terms of microroughness, reflectivity, laser damage threshold, residual stress, etc., has a close relation with the microstructure and the processing sequence of the material. In addition, the uniformity of the crystal grains and the heat-treatment processes largely affect the microroughness and the residual stress of the finished surface. Finally, an optimized processing method before diamond turning is given to obtain the best surface quality.
