Abstract: A micro end mill includes a shank made of a first material and a cutting tip made of a second, different material that is bonded to the shank. The first material can be, for example, carbide or high speed steel (HSS), and the second material can be, for example, cubic boron nitride (CBN), polycrystalline cubic boron nitride (PCBN), ceramic or polycrystalline diamond (PCD). The micro end mill is manufactured by producing a billet made of Superhard material using laser radiation, bonding the billet to a shank of the end mill, and removing material from the billet using laser radiation to produce a cutting tip made of the Superhard material. The laser radiation may comprise a laser beam encased in a water jet or a laser beam with a non-Gaussian intensity profile.

Abstract translation: 微型立铣刀包括由第一材料制成的刀柄和由与刀柄接合的第二不同材料制成的切削刀片。 第一种材料可以是例如碳化物或高速钢（HSS），第二种材料可以是例如立方氮化硼（CBN），多晶立方氮化硼（PCBN），陶瓷或多晶金刚石（PCD） 。 微型立铣刀通过使用激光辐射制造由超硬材料制成的坯料来制造，将坯料粘合到立铣刀的柄部，并且使用激光辐射从坯料移除材料以产生由超硬材料制成的切割尖端。 激光辐射可以包括封装在水射流中的激光束或具有非高斯强度分布的激光束。
