【摘要】 本文研究了一种铁基结合剂金刚石节块的氧化铝砂轮平面磨削。通过在线测量水平和垂直方向磨削力,研究了氧化铝砂轮平面磨削加工金刚石节块过程中的法向力、切向力、力比以及磨削比能变化特征。观察了磨削后的金刚石节块表面特征。比较了逆磨和顺磨条件下的磨削特征。结果表明,顺磨条件下的法向力、切向力以及磨削比能均高于逆磨,但是切向力与法向力的比值在两种磨削方式下基本相同。更多还原

【Abstract】 In this paper,a study was conducted to investigate the surface grinding of a iron-based diamond segments with an alumina grinding wheel.Vertical and horizontal forces were in-process measured.The characteristics of normal and tangential force components,their ratios and specific energy were subsequently studied for the grinding of the diamond segment.The morphologies of the ground segment surfaces were observed.Two grinding modes-up grinding and down grinding-were compared in the study.It is found that the normal force,tangential force and specific energy for the down-grinding are higher than the up-grinding. But the ratios of tangential force to normal force for the two grinding modes are comparable.更多还原
