【摘要】：為實(shí)現(xiàn)復(fù)雜、異形刀剪的端面磨削,提出一種空間端面磨削三軸聯(lián)動(dòng)控制方法。根據(jù)端面磨削的工藝特點(diǎn)與臥式端面磨床的結(jié)構(gòu)特點(diǎn),建立砂輪徑向進(jìn)給量、軸向進(jìn)給量、旋轉(zhuǎn)角度等加工參數(shù)與工件頂面磨削量、底面磨削量、磨削寬度等工藝參數(shù)間的函數(shù)關(guān)系,并結(jié)合端面的投影規(guī)律,實(shí)現(xiàn)一個(gè)旋轉(zhuǎn)軸與兩個(gè)平動(dòng)軸的三軸聯(lián)動(dòng)控制。建立砂輪軸向進(jìn)給誤差與砂輪直徑、刃線輪廓以及旋轉(zhuǎn)角度間的函數(shù)關(guān)系,并提出誤差補(bǔ)償方法。試驗(yàn)結(jié)果表明,所提運(yùn)動(dòng)控制與誤差補(bǔ)償方法能夠?qū)崿F(xiàn)復(fù)雜、異形刀剪的端面磨削。
[Abstract]:In order to realize the end surface grinding of complex and special-shaped cutter, a three axis linkage control method for spatial end surface grinding is proposed.According to the technological characteristics of the end surface grinding and the structural characteristics of the horizontal end grinding machine, the machining parameters such as radial feed, axial feed and rotation angle of the grinding wheel and the grinding amount of the top surface of the workpiece and the grinding quantity of the bottom surface are established.The functional relationship between grinding width and other technological parameters and the projection law of the end face are combined to realize the triaxial linkage control between one rotation shaft and two horizontal axes.The functional relationship between the axial feed error of the grinding wheel and the diameter of the grinding wheel, the contour of the edge line and the rotation angle is established, and the error compensation method is proposed.The experimental results show that the proposed method of motion control and error compensation can realize the end surface grinding of special-shaped cutter and shears.
