Modelling Complex Force Systems, Part 1: The Cutting and Pad Forces in Deep Drilling

This paper is the first part of a two-part series which analyzes the complex force system existing within a deep hole drilling operation where cutting forces exist at a single cutting edge and burnishing and friction forces exist at two pads. In this first paper the forces at the pads and cutting edge are determined by (1) assuming that the pad forces are related by coefficients and (2) by the use of complimentary dynamometers.
