A METHOD FOR INSPECTING THE SURFACE OF INTERNAL CAVITIES OF SPHERICAL PARTS (SPOSOB KONTROLYA POVERKHNOSTI VNUTRENNIKH POLOSTEI SFERICHESKIKH DETALEI),
Abstract
The paper presents a method for inspecting the internal surface of spherical details by the deflection of the constant level line from the standard value. To inspect details of complex shape, the lines of constant level are obtained by cutting the inspected detail by a layer of low reflection liquid. The level of the liquid is then changed by a desired amount, and the line is photographed on the same colored film with the use of interchangeable color filters. (Author)
