Analysis to the Influences of Cutting Force to Machining Deformation of a Titanium Alloy Thin-wall Tube

This paper took a titanium alloy thin-wall splined tube as the object of research, and mainly analyzed the influences of cutting force to machining deformation of part in turning process. The paper first introduced the structure composition and characteristic of splined tube, then established the mathematical model of cutting force in turning process according to the orthogonal experiment method and the multiple regression algorithm, and finally the influences of cutting force to machining deformation of splined tube was carried on the simulation analysis with the aid of the finite element analysis software under the different cutting conditions. The conclusions of research in this paper will have important practical significance to reduce the machining deformation of thin-wall part and optimize the cutting parameters of difficult-to-machine material.
