Thus it cannot produce the correct processing procedure, results in the numerical control processing can not be carried out with safety and reliabitlity, furthermore, the general post processor cannot output the unique auxiliary function of the machine numerical control system, which causes the characteristics and functions of the numerical control machine to be used efficaciously or correctly.Aimed to MIKRON UCP 600Vario five-axis machining center and Heidenhain iTNC 530 numerical control system, the special-purpose post-processing was studied, and the post-processing programme was develope in this paper. This programme can produce NC processing procedure according to the cutter location source file, and it is not necessary to conduct second alteration, then it can realize five-axis simultaneously controlled NC processing.Besides the ISO auxiliary function, HEIDENHAIN iTNC 530 numerical control system also has many other unique auxiliary functions. Aim to these functions and the particularity of five-axis NC machining and post-processing UG/Post Builder we conducted the output of the modality assistance function instruction M126, the M128 and the output of the non-modality assistance function instruction circulation 32. Through the user-defined functions, taking the Tcl as the development language, the subject has realized to output the total process time and each working procedure process time and tool-information while produces the NC procedure. The integration of special-purpose post-processing procedure and the UG has attained automatically to produce the numerical control processing code by transferring the post-processing procedure in UG.IIIKeywords：Five-axis machining NC programming Post processing Machining simulation Integral impeller Signature of supervisor:
