A method for fabricating a small-entrance, elliptical-gradient, large-deep cavity

To address the issues of insufficient performance and high cost associated with integral casting and additive manufacturing methods for parts with small-entry elliptical gradient deep cavities, and the difficulties, low efficiency, and high cost of metal removal methods, this invention proposes a machining method for elliptical gradient deep cavities with small entry points. The method involves first rough drilling and rough turning to obtain a deep hole. Then, a step-by-step machining approach is adopted, dividing the part into regions and machining them axially and radially. First, the part is tilted to machine the regions on both sides of the major axis of the ellipse. Then, the part is turned upright to machine the regions on both sides of the minor axis of the ellipse. During the upright machining, a radial layering and thin-cutting fast-running method is used. Several layers are machined using the first toolpath until the machining residue in the undercut and triangular regions is removed. Then, a second toolpath is used for contour machining to obtain a gradient deep cavity with an elliptical cross-section. Finally, the gradient deep cavity is precision milled until its internal dimensions and surface roughness meet the design requirements.
