Process for measurement of inaccessible small diameter bores
Abstract
Abstract A METHOD FOR THE ACCURATE, PRECISE AND RAPID MEASUREMENT OF RELATIVELY INACCESSIBLE OPENINGS OF SMALL INTERNAL DIAMETER, INCLUDING ESPECIALLY CAPILLARY SIZE OPENINGS. IN TAKING A MEASUREMENT, A SEGMENT OF THERMOPLASTIC MATERIAL OF CROSS-SECTION SOMEWHAT LARGER THAN THE DIAMETER THE OPENING OR BORE TO BE MEASURED IS FITTED UPON A MALE MEMBER, IS FORCED INTO AND COMPRESSED WITHIN THE INTERNAL OPENING TO BE MEASURED, THE THERMOPLASTIC MATERIAL THEREBY TAKING THE EXTERNAL SHAPE AND SIZE OF THE OPENING. THE THERMOPLASTIC MATERIAL, WHILE IN PLACE, IS HEATED, PREFERABLY ABOVE ITS SOFTENING POINT, SET, AND THEN WITHDRAWN FROM THE SAID OPENING. MEASUREMENT EX SITU OF THE OUTSIDE DIAMETER OF THE WITHDRAWN SEGMENT OF THERMOPLASTIC MATERIAL, BECAUSE OF THE RETENTION BY THE LATTER OF THE SIZE AND SHAPE OF THE INTERNAL OPENING, PERMITS HIGHLY ACCURATE AND PRECISE MEASUREMENT OF THE INACCESSIBLE INTERNAL OPENING.
