Abstract

A new mathematical model for multifacet drills (MFD) is developed using angle-solid-block approach to find the relationship of design parameters. The function of chisel edge angle is defined as ψ = f(ρ′, τ, αr) in order that the uncertainty of chisel edge geometry determined by existed model can be avoided. The effects of the new mathematical model on the geometry of chisel edge and main cutting edge are shown in this paper. In addition, the new mathematical model has the potential of designing and researching for many tools.
