磨粒有序排布曲面砂轮设计及磨削性能实验研究

提出一种曲面砂轮表面磨粒有序化排布的设计方法,制备磨粒有序排布和无序排布的2种曲面砂轮.通过磨削实验,从磨削力、砂轮磨损及工件加工形状误差等3个方面对比研究.结果表明:在整个磨削过程中,磨粒有序排布的曲面砂轮的磨削力总体上小于磨粒无序排布的曲面砂轮的磨削力.磨粒有序排布曲面砂轮的磨粒磨损一致性优于无序排布曲面砂轮的.整...

Experimental research on design and performance of curved grinding wheels with orderly arrangement of abrasive grains

A method to design orderly arranged grains on the surface of curved grinding wheels is proposed. Two types of curved grinding wheels with orderly and disordered arrangement of grinding grains are prepared. The grinding experiments are carried out to compare the performance of curved wheels from grinding force, grinding wheel wear and shape error of the workpiece. The results show that the grinding force of the curved grinding wheel with ordered grain arrangement is less than that of the curved grinding wheel with disordered grain arrangement during the whole grinding process. The abrasive wear consistency and shape accuracy of the machined workpiece of the curved grinding wheel with ordered grain arrangement are better than that of the curved grinding wheel with disordered grain arrangement during the whole grinding process. The orderly design of the abrasive grains on the surface of the curved grinding wheel can effectively improve the performance of the curved grinding wheel.
