摘要
根据双端面磨削原理,分析并确定砂轮直线修整相关的设计参数。以磨削区域内上下砂轮端面形状为研究对象,建立磨削区域的几何方程并进行分析计算,得到上下砂轮端面高度在工件几何中心运动轨迹上的变化曲线。分别确定固定式修整及插补式修整的最佳修整参数,获得磨削区域中理想的砂轮端面几何形状,提高工件的加工精度和精度稳定性,降低工件表面粗糙度。
The relevant design parameters of the wheel linear trim was analyzed and determined according to the principles of double disc grinding.Regarding the grinding wheel end surface topography as the research projects,some grinding zone geometry equations were established,calculated and analyzed to get the height curve of upper and lower wheel end surface on the workpiece geometric center trajectory.And then in order to obtain the ideal grinding wheel end surface geometric shape in the grinding zone,optimal dressing parameters of fixed trim and interpolation trim were determined respectively.These may improve the workpiece machining accuracy,accuracy consistency and reduce surface roughness.
