摘　　要：针对粗铣刀分屑槽形状的磨削工艺,对粗铣刀周齿分屑槽结构参数进行了定义,建立了加工坐标系及切深引导曲线方程;借助运动学理论,提出了砂轮磨削姿态和砂轮磨削轨迹的计算方法;在VC++环境开发了一套算法模块,并对其进行了仿真验证及与Numroto磨削软件的仿真结果对比。结果表明,该轨迹算法能够较好的实现预期效果,具有较好的刀具结构扩展性和加工精度。Aiming at the grinding process of the shape of chip groove of rough milling cutter,this paper defined the structural parameters of chip groove of peripheral teeth of rough milling cutter,and established the machining coordinate system and cutting depth guide curve equations.And with the theory of kinematics,the calculation method of grinding attitude and grinding track of grinding wheel was put forward.Finally,a set of algorithm modules was developed in VC++environment,which was verified by simulation and compared with the simulation results of Numroto grinding software.The results show that the trajectory algorithm can achieve the desired effect well,and has better tool structure extensibility and machining accuracy.
