摘　　要：针对圆弧立铣刀磨削中周齿前刀面与端齿前刀面的过渡问题,提出磨削圆弧刃前刀面的砂轮轨迹算法,以此实现周齿与端齿前刀面的光滑连接。定义了一种切深磨削点轨迹曲线,可以同时约束圆弧前刀面的宽度和前角;定义了圆弧刃在平面中的瞬时前刀面,计算在瞬时前刀面中的砂轮磨削轨迹和姿态,再经过空间坐标变换,得出砂轮实际加工轨迹。通过C++将算法编写为相应程序,进行仿真和实际加工验证,所得验证结果证明了该方法的正确性和可行性。Aiming at the transition problem between the rake face of peripheral flank and the rake face of end tooth in the circular arc end mill,proposing a grinding algorithm for the rake face of the arc edge that can achieve smooth connection between the two.Defines a depth-of-depth curve that can simultaneously constrain the width and rake angle of the arc rake face.Defines the instantaneous rake face of the arc edge and calculates the grinding path and attitude of the grinding wheel in it.After the space coordinate transformation,the actual machining track of the grinding wheel is obtained.Programming the algorithm into corresponding program by C++,and performming the simulation and processing verification.The obtained results prove the correctness and feasibility of the algorithm.
