Abstract: A high frequency flexure-based dynamometer (10) for measuring vibrations to use in determining cutting forces in a tool. The dynamometer device (10) may operate within a preselected high frequency range while measuring cutting forces less than about 1 N. The dynamometer (10) may include two coupled flexures that interact to produce vibration modes at the edge of a selected bandwidth of interest. These modes may produce a frequency response function within the desired frequency band that has a magnified response and is substantially constant. The dynamometer (10) may include a workpiece (38) mounted to one of the two flexures (12) and a one or more precision accelerometers (30) mounted to the first or second flexures. Finite element analysis may be used to optimize the flexure design.

Abstract: 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.
