激光沟槽化砂轮磨削力建模及沟槽角度优化
Modeling of Grinding Force and Optimization of Groove Angles of Laser Grooved Grinding Wheels
摘要
Abstract
The influences of laser dressing parameters on abrasive morphology and protrusion height were studied.The influences of grooved grinding wheel surface topography on grinding force were ana-lyzed,and the total grinding force model and the grinding force fluctuation model were established.The correlation law among groove pattern and groove angle and grinding force fluctuation was explored,and groove angle was optimized based on the principle of minimum grinding force fluctuation.The results show that the abrasive morphology after dressing is similar to the table shape,and the protrusion height of the abrasives is well fitted to the Rayleigh distribution function.When the grooving factor increases from 60%to 100%,the grinding force basically increases linearly.The average error between the predicted and ex-perimental values of the total grinding force is about 5.55%.In the symmetrical straight groove grinding wheel,the grinding force fluctuation increases with the increase of the number of chutes in a single groove pattern.The grinding force fluctuation model is a discontinuous function with groove angle.Except for the optimized groove angle,the fluctuation of grinding force decreases with the increase of groove angle.The grinding force fluctuation of the groove angle optimized grinding wheel is minimal,and the surface rough-ness and surface damage of the workpiece are the least.The above model may accurately predict the grind-ing force of the laser grooved grinding wheels,help to optimize the groove angles of the grinding wheel sur-face,and improve the surface quality of the workpieces.关键词
