| 摘 要： | 实际生产过程中球头铣刀主要用于曲面加工,但是关于球头铣刀曲面加工切削力的研究很少.本文针对曲面铣削加工中球头铣刀切削力预报的问题,通过离散近似将动态的切削过程分解为一系列进给方向和刀具与工件接触区不断变化的微小瞬态阶段,将剪切和犁切双重作用的静态球头铣刀切削力模型引入到自由曲面铣削载荷预报中,并选取一自由曲面工件进行铣...

| Abstract: | The ball-end mill is widely used to machine the free surfaces in the industry,but the study of the cutting force with ball-end mill is fewer.A method to predict the cutting force in ball-end milling of free surfaces with the Zconstant toolpath is presented.The dynamic cutting process is divided by discrete approximation into a series of elements with changing feed direction and contact area,and the cutting force prediction of milling free surfaces are completed using the static cutting force model with cutt... |
