Abstract: This study deals with the development of a new cutting model for drilling. This model is based on an experimental approach which links the drill geometric parameters to the mechanical actions of the cutting operation. Literature proposes many works about this subject in which analytical or numerical models answer the problem using behaviour laws, strain and stress shields, temperature. The presented method consists in correlating geometry and behaviour in an experimental way without modelling the real complexity of the phenomenon. Comprehension of the influence of geometric parameters on cuttingefforts for any part of the cutting edge is the main purpose of this work. The use of an original single variable cutting edge drill prototype allows fully quantifying forces and torques exerted on any point of the cutting edge.
