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.
