Paper Abstract

The cutting parameters have important effects on the surface condition of KDP crystal by single point diamond turning. In this paper, the characteristics of single point diamond turning have been researched, and a model that related the residual height of surface to the cutting parameters is established. The influence of spindle speed and the feed rate of cutting on KDP crystal surface roughness have been studied. Experimental results show that the surface condition can be improved by decreasing the cutting feed rate of KDP crystal. Another important trend is that by decreasing the spindle speed of the main-axis can't improve surface roughness efficiently while increasing the approaching velocity of KDP crystal at the same time. The reason can be explained as that the high spindle speed will cause exceeded temperature of the deformed zone, which will change the deformation mechanism of KDP crystal.
