| 摘 要： | 针对微细切削刀具的应用需求,在Aoyama等设计的椭圆柱球端铣刀的基础上,提出了一种简化结构的新型微细球端立铣刀的优化设计方案.应用微分几何方法对此类刀具结构进行数学建模,依据ISO刀具角度定义计算其静态工作角度,分析所设计刀具的切削能力;根据建立的数学模型进行刀具制备过程的分析,确定最终的刀具优化结构与制备工艺.所设计的微细球端立铣刀能够提高微细切削刀具切削部分的结构强度,同时显著降低刀具制备的难度.

| Abstract: | Considering the requirement of micro cutting tool, a new kind of micro ball-end mill was proposed based on the elliptic ball-end mill which was introduced by Aoyama, Kishinami and Saito. A mathematical model of this new tool was established by using differential geometry to obtain the angles of cutting tool in tool-in-hand system. Through the analysis of the manufacturing process of the tool, an optimal structure of the tool was designed eventually. This new designed tool could meet the need of cutting condition. It also has a stronger cutting edge and is easier to be manufactured. |
