Abstract

In this paper, a new theoretical approach for dynamical study in drilling operation is proposed. We use a finites element of beam design to develop a dynamical model for drilling machine-tool. This model takes in to account of the gyroscopic effect and its influence on the vibrations phenomenon appearing in drilling operation. It has also a big influence on the quality of machining surfaces and on the dispersion of the machine-tool when little deformations are taken in account. As a result of this modelling, initially modal analysis is carried out for the study of two cases: the simple model of the machine structure and a model with mass modifications. In the end of this paper, we present a simulation of the gyroscopic effect and the speed effect on the cutting forces fluctuation in drilling, axial and radial vibrations, the deformation energy and the hole circularity.
