一、问题的提出硬質合金端銑刀的設計同其它刀具一样,大致可分为两部分,其一为銑刀設計参数的計算,其二为具体結构的設計。松据所要求銑刀的前角γ_o、刃傾角λ_s;主偏角K_r、直径(指刀尖圆直径)d_o等主要原始参数計算出銑刀刀体上的設計参数。設計参数是直接保証銑刀使用性能的重要条件,也是进行具体結构設計及安排刀具制造工艺的依据。刀体上需計算的主要設計参数有;端面上刀槽的偏心距e;端面上槽 First, the issue put forward Carbide end milling cutter with the same design, can be divided into two parts, one for the milling cutter design parameters, the second is the design of the specific structure. According to the required milling cutter front angle γ_o, edge inclination λ_s; primary angle K_r, diameter (finger tip diameter) d_o and other primary parameters to calculate the cutter body design parameters. Design parameters is an important guarantee for the direct use of milling cutter performance, but also for specific structural design and arrangement of tool manufacturing process basis. Tool body to be calculated on the main design parameters are; end surface of the groove eccentricity e;
