【摘要】：提出了大型光學(xué)鏡面變壓強(qiáng)的高效研磨方法.傳統(tǒng)研磨中普遍采用常壓研磨的方式,很大程度上阻礙了去除率與收斂率的進(jìn)一步提高.大量實(shí)驗(yàn)表明去除效率與壓強(qiáng)之間并非線性關(guān)系,本文從研磨盤、磨粒與工件的幾何學(xué)關(guān)系推導(dǎo)變壓強(qiáng)條件下有效磨粒的分布規(guī)律,進(jìn)而建立壓強(qiáng)、磨粒運(yùn)動(dòng)形式與材料去除方式的映射關(guān)系,研究變壓強(qiáng)條件下材料去除機(jī)理以及磨粒運(yùn)行軌跡的微分幾何描述,進(jìn)而推導(dǎo)變壓強(qiáng)條件下的非線性去除函數(shù);通過音圈電機(jī)驅(qū)動(dòng)的變壓強(qiáng)研磨工具,利用機(jī)器人研磨平臺實(shí)現(xiàn)了大型光學(xué)鏡面的變壓強(qiáng)高效研磨.
[Abstract]:An efficient grinding method for large optical mirror with variable pressure and strong pressure is presented.In traditional grinding, atmospheric pressure grinding is widely used, which greatly hinders the further improvement of removal rate and convergence rate.A large number of experiments show that the relationship between removal efficiency and pressure is not linear. In this paper, the distribution law of effective abrasive particles under variable pressure is deduced from the geometric relation of grinding disc, abrasive particle and workpiece, and the pressure is established.The mapping relationship between the motion form of abrasive particles and the material removal mode is studied. The material removal mechanism and the differential geometric description of the movement path of abrasive particles under variable pressure are studied, and the nonlinear removal function under variable pressure is deduced.By means of variable pressure grinding tool driven by voice coil motor and robot grinding platform, variable pressure and high efficiency grinding of large optical mirror surface is realized.
