Abstract

The invention discloses a disc-shaped milling cutter for multi-curvature curved surface efficient numerical control machining and an application method thereof. The disc-shaped milling cutter comprises a first hollow column section, a second hollow column section and a hollow cone section, wherein the first hollow column section is located on the uppermost portion, the hollow cone section is used for connecting the first hollow column section and the second hollow column section, the hollow cone section is narrower in the upper portion and wider in the lower portion, the lower end face, the outer wall face and the inner wall face of the second hollow column section and the outer wall face, close to the second hollow column section, of the hollow cone section are all plated with sand, the sand plating height of the inner wall face of the second hollow column section is not smaller than 2 mm, and the projection of the sand plating area of the outer wall face of the hollow cone section in a vertical direction is not smaller than 2 mm. According to the milling cutter, the machining precision of products is effectively guaranteed, and the problems that a tool is seriously abraded and the loss rate is too high are solved.

Description

technical field [0001] The invention belongs to the technical field of numerical control machining of heat-resistant sections, and relates to a disc milling cutter for high-efficiency numerical control machining of multi-curvature surfaces and an application method thereof. Background technique [0002] The heat protection section is usually composed of metal shell, composite material heat protection layer, heat protection parts and so on. The segment of traditional regular shape (regular conical shape) can meet the processing requirements by simple turning. However, with the changes in the flight conditions and flight status of weapons, special-shaped and large-sized sections have emerged, and at the same time, the processing difficulty has become more and more difficult. The metal shell is laminated, heated and solidified to form a section heat-resistant shell assembly blank. [0003] Special-shaped and large-sized sections have a large margin in the local area, usually ...
