METHODS FOR MACHINING PROCESS PARAMETER ESTIMATION AND SYSTEMS THEREOF

摘要

A method for directly determining model parameters for a machining process includes the steps of providing a system having a machining tool and a workpiece, and machining the workpiece using the machining tool, wherein the machining induces motions in the machining tool or the workpiece. The motions are men measured. System characteristic multipliers (eigenvalues) are estimated from the motions, The eigenvalues are then related to results of at least one an analytical method or theoretical model to obtain a set of process model parameters.
