Paper Abstract

With the application of finite element (FE) software, a finite element model is established to simulate the cutting procedure for KDP crystals. Based on this model, the influential factors on cutting force of KDP crystal in ultra-precision cutting is analyzed. The study shows that the cutting forces will enlarge with the increment of the depth of cut, but the influence of depth of cut on the cutting force is more significant. The cutting force decreases as the cutting speed increases. The surface roughness decreases as the negative rake increases in the same cutting condition. Super-smooth surface of KDP crystal can be obtained when edge angle is negative rake angle. Finally, cutting experiments are carried out to validate the FE simulated results.
