摘要/Abstract

摘要： 为保证圆弧头立铣刀后刀面的加工精度，提出一种基于接触区域自适应调整的圆弧头立铣刀后刀面磨削轨迹精确计算方法。通过圆弧头立铣刀结构特征分解构建了后刀面的数学模型；通过计算砂轮和后刀面之间的磨削接触区域，自适应修正砂轮姿态，避免磨削干涉，实现了后刀面几何参数控制的准确性和一致性，并保证了曲面的光滑连接。最后，在VC++平台算法模块开发的基础上，通过加工仿真和磨削试验验证了该算法的有效性。

Abstract: In order to ensure the machining accuracy of circular-arc end mill flanks, a grinding trajectory accurate calculation method for circular-arc end mill flanks was proposed based on contact area adaptive adjustment. Firstly, the mathematical model of the flank was constructed through structural feature decomposition of the circular-arc end mill. Then, by calculating the grinding contact area between the grinding wheel and the flank, the grinding wheel posture was adaptively corrected to avoid grinding interference, which realized the accuracy and consistency of flank geometric parameter control and ensured the smooth connection of the curved surfaces. Finally, based on the implement of VC++ platform algorithm module, the effectiveness of the proposed algorithm was verified by machining simulation and grinding experiments.

Key words: circular-arc end mill, flank, grinding trajectory, contact zone, adaptive adjustment
