ABSTRACT:
A method of centering a hollow cylindrical piece of work comprises measuring the outside and inside diameters and contours of the work by means of outside- and inside-diameter-measuring instruments relative to the common centerline of the instruments taken as the virtual center of the work, inputting the measured values with corrections made for any deflection of the work and for any error arising from the instruments, to an electronic computer, and allowing the computer to memorize the information and operate to find the real center of the hollow cylindrical work on the basis of the stored information, whereby the location of the real center and machining allowances necessary for obtaining a product finished to the desired contours can be be computed.
