A Study of Three Dimension Cutting;Tipped Twist Drilling
3차원절삭에 관한 연구(초경DRILL의 효율성 증가)
Abstract
Carbide-tipped twist drill of new type which is better than traditional H.S.S twist drill has been developed successfully to drill steel work-pieces with high speed. This new carbide drill consists of a characteristic flature of special shape of cutting edge, chip pocket, and flute. The special design of the chip pocket and the flute guarantees both periodic fracture and smooth transport of chips along the flute. The carbide-tipped twist drill also allows one to apply more drilling force than conventional one and produce holes with high accuracy.
