Honing is an abrasive machining process that produces a precision surface on a workpiece and widely used in manufacturing engine cylinder walls, compressor bodies, valve bodies, bearings, hydraulic cylinders and so on. Investigation and acquisition of the honing force could be used to investigate the honing mechanism and optimize the processing parameter. But it is difficult to measure the force during the honing process because of the limited honing structure. This paper presents a measuring system for honing force. It introduces the measure theory and the measure system. The whole measuring system is validated by experiment.
