摘要：
This paper presents a real-time tool deflection compensation technique to improve micromilling machining accuracy. Lateral and axial errors of the cutter location (CL) caused by tool deflection were estimated using the cutting force and compensated by applying an additional feed to the workpiece that is equivalent to the estimated CL errors. To evaluate the proposed method, a workpiece holder comprising a three-axis stage and a tool dynamometer was installed on the work table of a machine tool. A proportional derivative (PD) position controller with a model-based tool deflection estimator was designed and implemented on a real-time computer to control the workpiece holder. Lateral and axial machining errors in side milling and radii errors in circular slot milling are discussed to demonstrate the effect of tool deflection compensation.
