Chaotic Dynamics of Cutting Processes Applied to Reconfigurable Manufacturing Systems Control

Résumé

There are already known and enounced into dedicated literature the limits of classic theory concerning cutting processes stability. Starting from this aspect and also from the need of designing an intelligent system to control cutting stability, to enable full use of RMS technological system productivity resources, this paper is a first step to a new approach of cutting process dynamics, seen as chaotic phenomenon. By using Chaos Theory tools (Lyapunov exponent calculation, Poincare maps), a specific parameter variation, characterizing cutting process (the cutting force), is analyzed, in order to reveal a chaotic model of this process. Such a model will allow a better understanding of phenomena connected to cutting processes (in)stability, same time with imagining a simple and efficient tool to control the stability of cutting processes developed on RMS.
