Mathematical Cutting Model Based on Experimental Approach: Drilling Application

Abstract:

The object of this work research tasks relates to the improvement of the cutting tools in drilling within the industrial framework of the aeronautical assembly. The stakes of the study consist in optimizing the lifespan of the tools according to a criterion of respect of geometrical quality and surface quality of the bored holes. This optimization relates to the geometry of the cutting part of the drills. The discussion thread of work thus tends to set up methods which make it possible to bind the geometry of the tools to the final quality of borings carried out. The study was divided into three stages differentiated and complementary to modeling of the physical phenomena induced by the process of drilling. The first stage [1] lies in describing the real geometrical parameters according to the parameters of grinding of the tool. While being based on the modeling of the geometry, the experimental cutting model enables to identify the mechanical actions of cut along the edge. Lastly, the phenomenological [2] aspect of the process associates the parameters of cut the final quality of the bored holes. [3].
