Dynamic Evaluation of a Linear Axis in Milling Using Modelling and Simulation Environment
نویسندگان
چکیده
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.

In this research, the feasibility of using mathematical modelling in the ball milling process has been evaluated to verify the hardness changes of an aluminium nanostructure. Considering the model of normal force displacement (NFD), the radius of elastic-plastic and normal displacement of two balls were computed by applying analytical modelling and coding in MATLAB. Properties of balls and alum...
