Abstract
A system for measuring radial cutting force for honing was developed to produce a highly efficient automatic in-feed internal honing machine based on honing force measurement. We present an outline of the developed measuring system and some results. The radial cutting force can be obtained from the measured value of wedge thrust for in-feed of honing stones. Piezo-electric force sensors were used to measure the wedge thrust. We estimated the cutting force ratio of the in-feed internal honing from tangential and radial cutting forces. An in-feed rate control system for internal honing was developed as an application of the radial cutting force measurement.
