In order to obtain high precision Fresnel lens, the processing technology of the single point diamond turning (SPDT) is investigated. Through the cutting experiments, compared the performance of Fresnel lens manufactured on different metal materials and by different diamond tools, respectively. The results show that material characteristics and tool nose radius affect the shape precision of the Fresnel lens, and the machining parameters affect the surface roughness. Therefore, choosing appropriate tool parameters and material is extremely important for improving the precision of Fresnel lens.
