Simulation Study on Milling Performance of Trapezoidal Micro-texture Ball-end Milling Cutter on the Rake Face

文章就前刀面梯形微织构球头铣刀铣削性能仿真展开研究。为了研究梯形微织构球头铣刀对切削性能的影响,在球头铣刀前刀面制备不同参数的梯形微织构。在CATIA中建立球头铣刀三维模型,将梯形微织构置入球头铣刀前刀面的刀-屑接触区域,并使用Deform-3D仿真软件对不同参数的刀具铣削过程进行仿真,将获得的铣削力和铣削温度作为主要影响因素,并建立了铣削力、铣削温度的预测模型,使用遗传算法优化选取了最佳微织构参数,即微坑直径为76.843μm,微坑深度为54.725μm,微织构间距为177.767μm,距刃距离为91.845μm,此时铣削性能最好。

This paper conducts simulation study on the milling performance of the rake face trapezoidal micro-texture ball-end milling cutter. In order to study the influence of trapezoidal micro-texture ball-end milling cutter on the cutting performance, trapezoidal micro-texture with different parameters were prepared on the rake face of the ball-end milling cutter. The 3D model of the ball-end milling cutter was established in CATIA, and the trapezoidal micro-texture was placed in the cutter-chip contact area of the rake face of the ball-end milling cutter. The milling process of the cutter with different parameters was simulated by using Deform-3D simulation software. The obtained milling force and milling temperature were taken as the main influencing factors, and the prediction models of milling force and milling temperature were established. The genetic algorithm was used to optimize and select the optimal micro-texture parameters, namely, the diameter of the micro-pit was 76.843μm, the depth of the micro-pit was 54.725 μm, the spacing of the micro-texture was 177.767 μm, and the distance from the micro-texture to the edge was 91.845 μm. The milling performance was the best at this time.
