碟形砂轮加工刀具螺旋槽的磨削参数研究

摘要

基于无瞬心包络原理，建立了刀具螺旋槽的数学模型，推导了螺旋槽磨削参数和设计参数之间的函数关系式；根据数学模型，利用MATLAB开发了用于计算螺旋槽磨削参数和数值仿真刀具槽形的人机交互式界面程序；将刀具仿真槽形与实际槽形进行对比，结果表明两者具有很好的一致性，这证明了数学模型的有效性。另外，初步讨论了设计参数与刀具磨削参数及槽形之间的变化关系。%Based on the theory of non-instantaneous center enveloping,a mathematical model of helical groove was established,and the function of grinding parameters and design parameters were deduced.According to the mathematical model,a human-computer interactive interface used to calcu-late the grinding parameters and simulate the groove section was developed,and then the section pro-file of the simulative groove and actual groove were compared.The results show a good agreement and verify the validity of the mathematical model.In addition,variations of grinding parameters and groove influenced by design parameters were simply discussed.
