Abstract

The invention relates to a method for processing a titanium alloy and FRP compound conical part with a centripetal notch, comprising the following steps: fixing the conical part on a workbench; roughly milling the four rounded corners of the conical part; rough milling the opening of the conical part; The side of the opening is processed by the spindle orientation, and the sag of the opening is semi-finishing; the opening contour and slope of the conical part are finely milled; the four fillet contours and the sag of the conical part are finely milled. This processing method reasonably allocates the process margin, controls the deformation, controls the precision of the inner hole of the large end of the part, and uses it as the positioning reference when opening, regulates the process parameters in the cutting process, improves product quality and processing efficiency, and increases the rigidity of the part. , Improve the stability during processing.

Description

technical field [0001] The invention relates to the technical field of machining, in particular to a method for processing a concentric notch of a composite conical part made of titanium alloy and glass fiber reinforced plastic. Background technique [0002] In recent years, with the continuous advancement of science and technology, material technology has developed rapidly. As a new type of material, composite material has gradually become one of the leading materials in the 21st century. Composite materials have the characteristics of light weight, high specific strength, specific modulus, corrosion resistance, high temperature resistance, and ablation resistance. They are ideal materials for weapons such as aircraft, missiles, and aerospace vehicles. "Metal + composite material" is a kind of structural parts that are relatively common in missile weapon systems at present. At present, it is mainly manufactured by winding, suiting, molding and other technologies, and then ...
