Abstract

Finite element solutions are used to analyze the effects of geometric and process parameters on the drill bit transverse vibrations. The effects of cross sectional geometry, of the flute helix angle, the drill rotational speed, and the thrust force generated during drilling on the drill transverse frequencies are investigated. Simulation results also show the transient vibrations of a drill bit under transverse cutting forces at the drill tip.
