In the inside diameter measuring method of measuring an inside diameter of a cylindrical work by supplying compressed air from one end of the work and by detecting a back pressure of the compressed air, a correction amount of measured value of the inside diameter according to a length of the work is obtained in advance by determining a change of measured value of the inside diameter with respect to a change of the length of the work, whereby the measured value of the inside diameter is corrected according to the length of the work. Thereby, even in the case where a plurality of works having a different length are measured, accurate measurement can always be made.

Abstract: Apparatus for forming and measuring a bore includes a rotating shaft with one or more metal cutting tools disposed on a cutting head and a non-contact, pneumatic gaging device mounted on the shaft for rotation therewith. The measuring device is advanced into the bore formed by the tools so that it measures the inner diameter of the bore as the rotating shaft is advanced into the bore during the cutting stroke. Accordingly, a single stroke of the boring apparatus serves both to form a desired internal diameter and to measure the diameter formed during the cutting stroke. In a preferred embodiment of the invention, the tools are held by a positioning device which allow the tools to be moved radially with respect to the shaft so that the diameter of the bore formed by the tools may be varied. If the measured diameter deviates from the desired diameter, the positioning means repositions the tools as necessary to achieve the desired bore diameter on a subsequent cutting stroke.
