DYNAMIC EVALUATION OF A LINEAR AXIS IN MILLING USING MODELLING AND SIMULATION ENVIRONMENT
Florin STRATULAT, Florin IONESCU, George CONSTANTIN
Abstract: Machine tools are designed to reach a given performance level in term of precision and static and dynamic stiffness. In this article, we present methods of evaluating linear axis dynamics starting from the dimensioning stage (simple dynamic model) up to complex modelling taking in consideration the disturbance force (constant and variable cutting force) and the controller. Further considerations are connected with the nonlinearity of the ballscrew stiffness and its influence upon the system behaviour.
Key words: drive, slide, workpiece, disturbance, model, root locus, Bode diagram, Nyquist diagram.
