The use of an X-ray three beam technique to improve the adjustment of bars for cutting

An adjustment method for bars before cutting which uses the properties of X-ray three-beam diffraction is described. This procedure avoids two types of cutting errors: miscuttings of the delivered bars and misalignments of the bars on the holder. However, the method cannot avoid growing errors of the quartz and nonregularities of the wire saw. Therefore, a sorting before the final treatment remains necessary. However, the yield of blanks with the selected cutting angle will increase significantly
