【Abstract】 With the continuous development of the turn-milling compound machining technology.Heterosexual complex rotary parts increasingly appeared in the engineering application.In order to meet processing requirements of this kind of parts,orthogonal turn-milling machining method has been widely used.On the basis of analyzing the lining structure of the large diameter sleeve type parts,by using VERICUT software to do the simulation,the processing method of orthogonal turn milling was proposed to realize the machining process,The cutting process of this kind of parts was realized by the synthetic motion of high speed cutting and the rotating of the parts.In the research on the processing method of the inner wall of the large diameter sleeve type parts,The relationship between the compensation of tool length compensation and the over cut of the parts in the machining process was summarized.It is the first time to propose and establish the compensation amount of the tool length in the orthogonal turn milling,the rule of cutting tool length compensation algorithm was determined for the machining process of this kind of parts.It successfully solved the problem of over cutting of large and complex shaped rotating parts in orthogonal turn milling machine.The programming efficiency was improved by adding the macro program segment.It also shortened the processing cycle,and ensured the quality of processing.更多还原
