鑽削是金屬加工中一種非常普遍的加工法,而其切削效率受幾何形狀影響甚鉅,但
限於鑽頭外型複雜,至今仍未有一套完善的方法分析其幾何形狀。本文以雙槽鑽頭為對
象,以錐形研磨輪研磨其鑽頂形狀,期使能夠提供一套鑽頭幾何形狀的數學形式。
本文首先對於鑽槽的研磨方式加以研究,並以實際鑽頭為例,分析共軛法應用在此
處之可行性,接著以軌跡法研磨鑽槽曲面。在鑽頂形狀的研磨中,吾人則是以齊次矩陣
轉換法配合鑽頂幾何關係,首先求出鑽腹以及鑿刃之數學形式,再配合幾何關係求出鑽
頂角、鑿刃角等的數學形式,並且以數值方法分析各參數對於鑽頂角以及鑿刃角的影響

The performance of a drill is affected by the geometry of its point. The available mathematical representations of drill point geometry are inadequate to describe the variation of the drill point design. Precise drill geometry improves drilling performance, and efficiency of drilling, and as well as drill life. This paper provides representations of drill geometry. The mathematical approach of drill flute is based on the kinematic relationships and geometry of the flute and grinding tools. A mathematical model for drill flute is established with the application of the Homogeneous Transformation Matrix to describe the shape of the drill flute accurately. The mathematical model of drill point geometry developed is also based on the theory of Homogeneous Transformation Matrix and the geometry of the drill point and the grinding tools. The mathematical model includes some geometrical shapes which infect the drilling performance such as drill flank, chisel edge, drill point angle, and chisel edge angle, etc. The affection of the grinding parameters is also discussed. The mathematical model provides the development of the relationship between design parameters and the grinding parameters to predict and control the whole drill geometry.
