Algorithm for Modeling the Thermo-Mechanical Field Dynamics, Based on B-Spline Functions, with Application to Machining System

Résumé

Manufacturing systems adaptive control, having as final purpose products fabrication in conditions of maximum efficiency and by respecting required quality (precision) specifications, can be done only by permanently identifying these systems. Manufacturing systems identification is realized, in fact, by identifying characteristic fields. Because process conditions continuously change during manufacturing, it appears the necessity of modeling system dynamics. This paper presents a specific tool, designed to enable manufacturing systems thermo-mechanical fields dynamics modeling, based on B-spline functions. A numerical application, in the case of a lathe vibrations field is also presented.
