基于螺旋刻划方法的KDP晶体临界切削厚度研究
Research on Critical Cutting Thickness of KDP Crystals by Spirally Grooving
摘要
Abstract
In order to achieve the CCT related on the cutting condition, a novel method of spiral grooving of KDP crystals using single diamond tool was proposed.A calculation for CCT was established based on the characteristic parameters of micrograph of groove.The influence of cutting speed and anisotropy of KDP on the CCT was analyzed.The CCT achieved by novel method was verified by experiments of cutting KDP crystals.The results indicated that the effect of anisotropy of crystals on the CCT is obviously, and the cutting speed in low speed has insignificant influence on the CCT.The cutting parameters are selected according to CCT obtained by method above, ductile mode cutting of KDP crystals in all crystalline orientation can be achieved, a super smooth surface with roughness of 2.57 nm (Ra) is achieved.关键词
