Measuring arrangement for the detection of dimensions of test specimens, preferably of hollow bodies, in particular of holes in workpieces, as well as a process for the measurement of such dimensions

摘要

In the machining of workpieces as a rule, it is required that the machining accuracy, certain requirements. Dollars a by the measuring arrangement and the method in such a way that the dimensions of the test specimens and with high precision can be reliably detected, the measuring arrangement an endoscope device, with which consists of two exit apertures the same line pattern for the formation of a moire effects - pattern on the surface of the circuit article 27, to be tested can be projected. The moire effects - pattern is detected with a camera. In the method, on the upper side of the circuit article 27, to be tested a moire effects - pattern is generated, which is detected and evaluated. Dollars a with the measuring arrangement and the method can be a moire effects - pattern evaluating, from which the dimensions to be measured at the specimen in a simple and nevertheless can be determined with very high precision.
