摘　　要：通过TG砂轮缓进深切磨削超高强度钢CSS-42L试验,研究了砂轮线速度、工件进给速度、磨削深度等磨削参数对磨削力、力比和磨削比能的影响规律。试验表明:切深、工件进给速度对TG砂轮缓进深切磨削CSS-42L磨削力影响十分显著,砂轮线速度的影响相对较小;增大砂轮线速度,磨削力比减小,增大工件进给速度和切深,磨削力比增大。磨削比能es随着当量磨削厚度aeq的增大而减小,当aeq<0.06μm时,磨削比能的下降趋势明显;当aeq>0.06μm时,随当量磨削厚度增大,磨削比能下降趋势越来越平缓。试验条件范围内,TG砂轮缓进深切磨削CSS-42L钢时最小比能为70J/mm3。By creep feed grinding of CSS-42 L with TG wheels, the influence of process parameters（wheel speed, workpiece speed and depth of cut） on grinding force, force ratio and specific energy are investigated. The results show that the wheel speed has the least effect on grinding force among process parameters. The force ratio decreases with the rise of wheel speed and increases with the rise of the workpiece speed and depth of cut. The specific grinding energy decreases steeply with the increase of equal depth of cut when aeq 0.06 μm, and the decrease becomes slow while aeq 0.06 μm. The minimum value of specific energy of CSS-42 L with TG wheels is about 70J/mm3 under the experimental conditions.
