For establishing extremely accurate length dimensions of working gauges it has been conventional practice to subject a working gauge member to a fine machining treatment and to compare the worked out dimension with standard gauge blocks, which are very expensive, or to control the dimension by means of still more expensive high precision measuring instrument. The invention provides for a system comprising both special standard gauge blocks (2) and special working gauge members (44) as well as an associated specialized measuring device (Fig. 3), by means of which a working gauge (44) may be produced by a simple length adjustment of two mutually fixably displaceable elements (4, 8), this adjustment being effected in the measuring device by comparison with the dimension of a standard gauge block as beforehand measured out in the measuring device. The gauge blocks (2) and the working gauges (44) may be similarly shaped, viz. consisting of a cylindrical body (4) and a measurement defining pin (8) projecting thereform, this conditioning a cheap design of the gauge blocks and an easy adjustability of the working gauges. |
