【摘要】 使用电镀金刚石砂轮对SiC颗粒增强Al2024复合材料进行端面磨削加工试验研究。研究结果表明,端面磨削加工能获得高质量的加工表面,在所采用的试验参数范围内,表面粗糙度在Ra为0.185μm和Ra为0.512μm之间,已加工表面残余应力表现为压应力;磨削加工参数对切向力和法向力的影响不大,并且在不同的加工条件下均保持较小数值。轴向磨削力大于其他两个方向的磨削力,并且随着磨削深度的增大而明显增大。更多还原

【Abstract】 An experiment was made on the face grinding of 2024Al composites with SiC particle through the use of electroplated diamond wheel.The results showed that high quality processed surface was achieved by using face grinding technology.Within the parameter range of this experiment,the roughness was between Ra0.185 μm and Ra0.512μm,residual stress of processed surface was compressive stress.Grinding parameter had little effect on tangential force and normal force.Axial grinding force increased with the increasing of grinding depth and was stronger than grinding forces in other two directions.更多还原
