摘要

立铣刀切削过程中的能量流承担着驱动物质流流动的功能，能量流的变化特性决定着铣刀切削物质流的传递转换关系，进而影响铣削加工表面形成过程。依据振动作用下的铣刀瞬时切削行为，揭示切削加工过程中的能量构成及其传递转换关系；利用节点瞬时状态参量，定量表征铣刀能量流各个节点的能量；利用流量、流动势和阻，揭示能量流结构的流动状态；利用㶲效率，揭示切削过程输出有用能的分布特性；并利用铣刀瞬时切削能量效率与切削比能进行实验验证。铣刀瞬时切削能量效率与切削比能的解算结果与实验结果的灰色相对关联度大于0.81，相对误差小于19.9%，验证结果表明采用上述模型和方法，可揭示出铣削过程中能量流的变化特性。

Abstract

During the cutting process with an end mill, energy flow drives material flow. The variation of energy flow dictates the transformation and transfer of material flow, thereby influencing the surface formation during milling. Based on the instantaneous cutting behavior of the milling cutter under vibration, energy composition and transfer conversion relationship was revealed during the cutting process. Instantaneous state parameters of nodes to quantitatively characterize the energy of milling cutters at each node was used. Flow rates, flow potentials, and resistances were employed to describe the flow state of the energy structure. Exergy efficiency was used to analyze the distribution characteristics of useful energy output during the cutting process. Experimental validation was performed using the instantaneous cutting energy efficiency and specific cutting energy of the milling cutter. The results showed that calculated and experimental results of instantaneous cutting energy efficiency, calculated and experimental results of specific cutting energy of the milling cutter exhibited a grey relative correlation coefficient exceeding 0.81, and a relative error of less than 19.9%. The aforementioned models and methods enable the revelation of the dynamic variations in energy flow during the milling process.
