一种凸轮轴数控磨削加工方法
摘要：
本发明公开了一种凸轮轴数控磨削加工方法，包括以下步骤：1).利用计算机的数控程序控制数控磨床中作为X轴的砂轮架的横向进给系统和作为C轴的头架的旋转系统；2).计算出砂轮架的位移X(θ)、速度V(θ)、加速度a(θ)、加加速度J(θ)和头架转速ωP(θ)的理论值，将这些理论值输入编程软件，由编程软件自动生成砂轮架位移控制的数控加工子程序；3).采用MATLAB软件工具得到砂轮架的最大速度Vmax(θ)、最大加速度amax(θ)和最大加加速度Jmax(θ)的实际值等。本发明方法与现有技术相比，具有操作方便，能自动生成自动生成对砂轮架位移控制的数控加子工程序和头架转速控制的数控加子工程序，磨削精度高，型线误差小于0.015mm，无明显的波纹和振纹现象。
摘要（英）：

The invention discloses a numerically controlled grinding machining method of a camshaft, comprising the following steps of: (1) controlling a transverse feeding system of a grinding wheel bracket as an X-axis and a rotating system of a head holder as a C-axis in a numeric control grinder by utilizing a numerical control program of a computer; (2) calculating the theoretical values of displacement X(theta), velocity V(theta), acceleration a(theta), jerk J(theta) and head holder rotation speed omegaP(theta) of the grinding wheel bracket, inputting those theoretical values into programming software, and automatically generating a numerical control machining subprogram of the displacement control of the grinding wheel bracket by the programming software; and (3) obtaining the actual values of the maximum velocity Vmax(theta), the maximum acceleration amax(theta) and the maximum jerk Jmax(theta) of the grinding wheel bracket by utilizing an MATLAB (Matrix Laboratory) software tool. Compared with the prior art, the method provided by the invention has the advantages of convenience for operation, high grinding precision, no remarkable corrugation or chattermark situation and automatic generation of the numerical control machining subprograms for controlling the displacement of the grinding wheel bracket and the rotation speed of the head holder; in addition, the error of molded lines is smaller than 0.015mm.
