多颗粒金刚石小砂轮磨削仿真及实验
Simulation and Experimental Study of Small Grinding Wheel with Multi-grains Diamond
摘要
Abstract
An abrasive grain trajectory model of grinding engineering ceramics in axial deep creep-feed grinding with small grinding wheel was established and the relationship among cutting parame-ters and the law of abrasive grains'motion was revealed.The effects of feeding speed on the crushing of edge,grinding force and the diamond abrasive wear were analyzed according to the actual machining of ceramics by changing processing parameters.The experimental results are consistent with the simu-lation ones.Experiments were based on appropriate experimental schemes and force measuring sys-tem,the changing of the diamond grain's curve radius was real-time detected by edge detection and curve fitting of profile.This paper also provides references on how to use the feed speed that is reason-able to enhance the processing efficiency by removing ceramic chunks via the splitting and to reduce the damage on the workpiece and the grinding wheel.关键词
