CREATION OF CONTROL PROGRAMS FOR MECHANICAL TREATMENT OF INTERNAL SURFACE OF TRIHEDRAL ANGELS OF PARTS ON NC MACHINE

S.F. Lyakun, V.E.Yurkevich

There is described the way of development of control program (CP) for process of internal surface of trihedral angle (TA) in single productions: aerospace, experienced, instrumental, special tools. Necessary calculations and methods of their check are described for example Microsoft Excel. For this there are as drawings it’s seven pages Microsoft Excel in addition given function as a table – flat angle of TA as a function from linear angle with tolerant mechanism of interpolation. There is given analyse of testing. There is arise a question of calculation and creation CP for processing of internal surface of TA as cycles of tool with NC machines.

Key words: trihedral angles, control program, iterations, deduction, finite differences, cycle of NC machine, interpolation, extrapolation, number series, tolerant system, axiomatic method, bound reliability.
