Here the technique of the in-process measurement of tool wear (tool-life) is discribed. Tool-wear is a parameter of estimated function concerning the productivity and economical factors in the cutting process. Measuring method of the tool wear is shown as follows : The tool wear is measured directly when the tool is removed to a proper place at the time of tool changing. The method of the measurement is to sense the shape of the tool edge by several electric micrometers and to determin the tool wear by comparing it with the first condition. According to the results of the experiments, it is proved that, in the wet cutting, the tool can be measured with a comparatively high accuracy. On the other hand, in the dry cutting, the measuring error caused by the cutting temperature might sometimes appear. However, if the cutting temperature is compensated, a high measuring accuracy can be obtained even in the dry cutting. Moreover automatic cutting tests are examined by utilizing a trial device as one of pratical methods.
