PROBLEM TO BE SOLVED: To provide an in-process measuring device capable of simply and precisely measuring the dimensions of a grinding wheel.;SOLUTION: A pressure sensor portion 3 coming close and opposing to a grinding surface of the grinding wheel 2 rotating about a shaft 2a is provided, and a grinding fluid 4 is supplied between the grinding wheel 2 and the pressure sensor portion 3. The pressure sensor portion 3 is supported by a displacement means 7 composed of a slight movement mechanism 7a and a rough movement mechanism 7b. The pressure sensor portion 3 is displaced to make measured the dynamic pressure of the grinding fluid 4 by a pressure sensor 3a provided on the pressure sensor portion 3 become a specified value, and the dimensions of the grinding wheel 2 is calculated on the basis of the displacement amount of the pressure sensor portion 3 measured by a laser displacement gauge 9. Even if the diameter of the grinding wheel 2 is decreased due to wear, the distance between the grinding wheel 2 and the pressure sensor portion 3 is kept at a specified distance, so that the pressure sensor 3a can precisely measure the dynamic pressure, and the dimensions of the grinding wheel 2 can be precisely measured.;COPYRIGHT: (C)2002,JPO
