Abstract
Obtaining a straight cutting edge in the case of small twist drills warrants an accurate grinding of the “primary” flute. A transformed mathematical model which would yield the proper flute-grinding wheel profile for a straight cutting edge is developed from an existing orthogonal flute model. Also discussed in this paper is a mathematical model that describes the wheel profile for the “secondary” (non-cutting edge) flute as a function of parameters such as land width, web thickness and chip removal capacity of the drill. The model enables an analysis of the effects of improper wheel setting and point grinding on the straightness of the cutting edge. From this analysis, an optimum wheel profile that would grind a maximum number of acceptable flutes can be obtained.
