中文摘要：

针对微细切削刀具的特点与应用需求，设计一种斜圆柱结构的新型微细球端铣刀，将铣刀球端刀刃复杂的空间曲线转化为易加工的平面曲线。根据所设计铣刀的几何结构特征，从制造工艺方面进行刀具结构的调整，分析刀具的刃磨成形原理，并在微细刀具数控刃磨机上完成该刀具的制作。通过与传统螺旋槽球端铣刀和椭圆柱刃型球端铣刀的切削性能对比试验，研究所设计刀具的切削性能。试验结果表明，所设计的微细球端立铣刀在显著降低刀具制备难度的同时，具有较高的切削刃强度，能够满足硬脆性材料的微细切削要求。

英文摘要：

According to the characteristics of micro cutting tools and their application requirement, a new design method of micro ball end mill with helical cylindrical structure is proposed. It changes the cutting edge of ball end milling from the complex space curve into a plane curve. Based on the geometric structure characteristics of the new designed micro ball end mill, the cutting tool structure is optimized with respect to the manufacturing process. Through the analysis of the principle of tool grinding process, the designed tool is fabricated in micro NC grinder. The cutting performance of the new designed tool is investigated through cutting experiment compared to the cutting performance of traditional spiral groove ball end milling and elliptical ball end mill. The results indicate that the designed micro ball end mill can achieve higher cutting edge strength, which can meet the micro cutting requirement for hard brittle materials. In the meantime, the complexity of cutting tool preparation can decrease dramatically.
