Abstract:
The present invention provides a method for accurately and simply measuring a blade width (W) of a blade tip section (1) of a grooving tool mounted on a machine tool. The blade tip section (1) is divided vertically or laterally and imaged so as to capture, one side at a time, a first-side corner section (2) formed on a first blade-width-direction side and a second-side corner section (4) formed on a second blade-width-direction side, of the corner sections formed at both ends of the blade tip section (1), the terminal end of each corner section of an imaged picture (3) of the first side of the blade tip section in which the first side of the blade tip section (1) is imaged and an imaged picture (5) of the second side of the blade tip section in which the second side is imaged is acquired, and, on the basis thereof, a blade width (W1) of the imaged picture of the first side of the blade tip section is measured from the imaged picture (3) of the first side of the blade tip section and a blade width (W2) of the imaged picture of the second side of the blade tip section is measured from the imaged picture (5) of the second side of the blade tip section to carry out computational processing on the basis of these values and determine the blade width (W).
