Abstract
An approach for the systematic choice of process parameters by observing the entire machining process in milling is presented. There is a varying workpiece dynamics due to the machining, wherefore a distinct change of stability characteristics is possible. The new contribution of this paper is an approach using parametric model order reduction in stability analysis. Both parametric model order reduction and stability analysis of time-delayed systems are topics of current research although their combination is hardly investigated. The approach is very efficient compared to full models or other ideas described in literature, like parametric model order reduction based on substructuring. Thus, the continuous representation of the varying workpiece dynamics enables stability analysis as well as time-domain simulations with reasonable computation times.
