HIPSN陶瓷磨削力试验研究与仿真
|
摘要
为探索金刚石砂轮磨削HIPSN(热等静压氮化硅)陶瓷时,磨削工艺参数对法向、切向磨削力的影响情况。设计正交试验重点研究磨削深度、砂轮线速度、工件进给速度等磨削工艺参数对法向、切向磨削力的影响规律,同时基于ABAQUS建立单颗金刚石磨粒切削HIPSN陶瓷有限元仿真模型,将试验结果与仿真结果进行对比。结果表明,提高砂轮线速度、减小磨削深度、降低工件进给速度,法向、切向磨削力均减小。磨削力比在(8～15)之间。试验结果与仿真输出结果基本一致,验证了该仿真模型的正确性。
To explore the effect of grinding process parameters on normal and tangential grinding force when grinding HIPSN (Hot-Isostatic Pressing Silicon Nitride)ceramics with diamond grinding wheels,the orthogonal experiment was designed to study the influence of grinding process parameters on the normal and tangential grinding force,such as grinding depth,wheel speed and workpiece feed rate,etc. At the same time,a finite element simulation model of HIPSN ceramics for single diamond abrasive cutting was established based on ABAQUS,and compares the experimental results with the simulation results. The results show that the normal and tangential grinding forces are negatively correlated with the wheel speed and are positively correlated with the workpiece feed rate and grinding depth. Grinding force ratio is between 8 and 15. The experimental results are basically consistent with the simulation output,which verifies the correctness of the simulation model.
