«UNEXPECTED TROUBLES» IN TRIHEDRAL ANGLE PROCESSING ALGORITHM OR ABOUT PLANE ANGLE PROPERTIES OF TRIHEDRAL ANGLE

Станислав Федорович Лякун, Владимир Евгеньевич Юркевич

Abstract


The plane angle (PA) properties in the trihedral angle (TA) are described. But “unexpected troubles” of these properties arise at the development of the TA processing technology. Because if you do not take into account the properties of the plane angles when testing the algorithms for calculation and processing of the PA, the improper conclusion will be made that these algorithms are useless! In particular, the algorithm is applicable at the manufacturing of the deep-space communication equipment, waveguides, bodies of the microwave integrated modules, radar equipment as well as in the machine computer numerical control unit as cycle named “trihedral angle”. It means that the trihedral angle processing technology, which has not been born as yet, will be “dead”. In the article four properties of the plane angles are described in terms of the trihedral angle fabricability. Three of them are known in the mathematics. The forth property is proven for the first time. The required calculations to check the creation of the control program and algorithm for processing of the TA are given with a help of Microsoft Excel program. The authors can send the algorithm realized in Microsoft Excel with the user manual by the e-mail.
