Abstract

A controller for a tool drive that collects force data and displacement data from the tool drive. The controller generates a stiffness model representing a workpiece using the force data and the displacement data. The controller further collects a force signal from the tool drive. The controller determines deflection of the workpiece using the force signal and stiffness model. The controller determines a resonant frequency of the workpiece using the stiffness model. The controller modifies an oscillation frequency and/or a rotational frequency of a spindle of the tool drive based on the resonant frequency. The controller also determines a location of a tip of the tool drive using the force signal.
