Wear phenomenon analysis apparatus of cutting tool edge and evaluation of several tool edges

This paper reports wear phenomenon analysis apparatus of cutting tool edge and evaluation of several tool edges. Generally, to analyze the wear phenomenon of the cutting tool edge, a CNC lathe is used for cutting, and the state of the cutting tool edge before and after cutting is observed and compared. However, there are problems that cutting with a CNC lathe needs a higher cost and use of the lathe in the production site is not recommended for productions. The authors thought that it would be possible to easily analysis without using a CNC lathe by developing a small wear phenomenon analysis device. As a result of experiment using the device, it was confirmed that the cutting resistance was reduced when the cutting tool edge was polished.
