For the further development of the FMS systems, this paper reports about a new measuring system developed for the multi-purpose understanding of the geometric features of cutting tool edges having serious influences on the machining outputs. In this system, to detect 3D features of both tool face and tool flank only from the 2D microscopic observation of the tool face and describe an overall 3D geometric feature of the tool edge as a digital 2D image, and also to enable non-expensive system development, two convenient measuring principles are utilized, that is the scanning optical section method for the tool face contour mapping and the cutting edge profile comparison method for the flank wear land estimation. Based on these, an experimental hardwear was arranged and various processing softwears were developed, and also they were applied to an observation of the cutting edge wear development in some cylindrical turning experiments, to show that various effective cutting edge parameters could be easily extracted from the integrated tool face image recorded and that sufficient accuracy and resolution for practical use could be obtained.
