摘　　要：对工业纯钛(TA2)进行车削加工正交切削试验,分析切削用量和表面粗糙度的关系。极差分析表明:切削用量中进给量对表面粗糙度影响最大,其次是切削速度,切削深度影响最小;表面粗糙度随着进给量的增加呈线性增大,随切削深度的增加而逐渐增大;加工TA2过程中,随着切削速度的增加,表面粗糙度值整体呈减小的趋势。由于切屑形态的变化造成切削过程不平稳,引起刀具振动,导致表面粗糙度值产生波动。The orthogonal cutting test of turning commercial pure titanium（ TA2） is conducted to analyze the influences of cutting parameters on surface roughness. The range analysis shows that the feed rate,the cutting speed and the cutting depth has the most effect,a greater effect and the least effect on surface roughness,respectively among cutting parameters. With the feed rate and cutting depth increasing,surface roughness increases linearly,gradually and respectively,with the cutting speed increasing,surface roughness decreases slowly during the machining of TA2. It shows that cutting process is not smooth because of the change of chip morphology,which causes tool vibration,then leads to the fluctuation of surface roughness.
