Methods for Machining Process Parameter Estimation and Systems Thereof

摘要

A method for directly determining model parameters for a machining process that includes the steps of providing a system having a machining tool and a workpiece, and machining the workpiece using the machining tool, where the machining induces motions in the machining tool or the workpiece. The motions are then measured and used to estimate system characteristic multipliers (eigenvalues). A set of process model parameters is obtained by relating the eigenvalues to the results of an analytical method, a theoretical model or both.
