Abstract
In a state of separating a front end face of an air injecting nozzlefrom a worked work W by a predetermined interval h, the air injecting nozzleis moved at a constant speed in an X axis direction, injects air from an injecting holeof a nozzle main bodyand is moved to pass centers OOof worked holes Wb, Wc of the work W. A variation in a pressure is measured by a pressure measuring unitX axis coordinates of the centers OOof the holes Wb, Wc, a hole diameter E and a center interval distance Dare calculated based on coordinates of center points TTof inclined portions Ld, Lu of a curve Lx of the pressure relative to the measured X axis coordinate.
