摘要

受刀齿误差影响，铣刀沿轴向存在多种刀齿分布，振动作用下具有多重刀齿分布的铣刀，其切削行为呈现多时变特性，导致切削过程中切削层厚度变化和铣削表面形貌分布具有复杂性和不确定性。依据铣刀结构和刀齿误差，获取沿铣刀轴向的多重刀齿分布序列，构建振动作用下多重刀齿分布的瞬时切削层厚度和铣削表面形貌分布解算模型，揭示沿铣刀轴向的单齿、多齿不等齿距和多齿等齿距分布的动态切削行为特征，阐明刀齿误差和铣削振动对铣刀瞬时切削层厚度及铣削表面形貌分布多样性的影响机制，并进行实验验证。结果表明，采用上述模型与方法，可揭示出振动作用下多重刀齿分布铣刀的动态切削行为及铣削表面的形成过程。

Abstract

Due to influence of tooth errors, multiple tooth distributions along axial direction of milling cutter exist. Milling cutter with multiple tooth distributions under vibration exhibit multi temporal characteristics in cutting behavior, resulting in complex and uncertain changes in cutting layer thickness and morphology distribution during cutting. Based on structure and tooth error, a sequence of multiple tooth distributions along axial direction of cutter is obtained, and a calculation model for cutting layer thickness and morphology distribution of multiple tooth distributions under vibration is constructed. Cutting behaviors of single tooth, multi tooth unequal pitch, and multi tooth equal pitch distributions along cutter axis are revealed. Influence mechanism of error and vibration on instantaneous cutting layer thickness and morphology distribution diversity is elucidated and experimentally verified. The results indicate that the above method can reveal dynamic cutting behavior of multi tooth distribution cutters under vibration and formation of milling surfaces.
