Effect of abrasive particle arrangement on surface morphology ground with pyramid belt

To study the influence of grain arrangement on the surface profile of the workpiece, a mathematical model and its corresponding analytical algorithm of pyramidal abrasive belt grinding were established. The roughness value was simulated and predicted with Abaqus software. Grinding tests were carried out on the robot grinding system platform with pyramidal abrasive belt, and the surface profile were inspected and then compared with the simulation. The results show that the simulated roughness and the measured values have similar variation trend with good consistency, where the error is within 0.03 μm and the maximum error rate is 16.6%. The theoretical simulation and test results remain consistent, indicating that the model could be used to predict the surface roughness of workpiece ground with pyramidal abrasive belt.
