摘要
根据超声振动抛光原理分析了弹塑性材料抛光过程中的材料去除方式;建立了弹塑性材料的材料去除模型,给出了磨粒速度、冲击载荷和工件表面受力变形的数学表达式;分析讨论了抛光过程和抛光参数的影响并用已有实验验证了该模型的合理性。
In terms of the principle of ultrasonic vibration polishing,the material removal method in the elastoplastic material polishing process is analyzed.The material removal model for elastoplastic material is established,and the mathematical expressions of abrasive particle velocity,impact load and force on the surface of the workpiece are given.The effects of the polishing processing parameters on the material removal were discussed and analyzed,and the rationality of the model was verified by using the existing experiments.
