Abstract

The invention belongs to the technical field of precision machining, and discloses a three-axis numerical milling machining method for a small-size blade. According to the three-axis numerical millingmachining method for the small-size blade, three-axis numerical milling is selected during blade manufacturing, specifically, a blade basin surface is milled firstly, then a blade back surface is machined, but when the blade back surface is machined, due to the fact that the blade basin surface is machined and the thickness of a blade body is small, the blade profile is prone to being deformed due to cutting force, and the product quality is unqualified. In addition, the surface of the blade is prone to being bitten in the machining process, and the profile precision is difficult to meet therequirement. In order to solve the deformation problem, a blade basin cavity is fully poured with auxiliary alloy with the melting point lower than that of a machining material when the blade back surface is machined, and the quality problem cannot be brought to the blade. After the auxiliary alloy is solidified and crystallized and the blade back surface is machined, the auxiliary alloy is removed through heating. The machining method is simple, high in efficiency and low in equipment requirement, and therefore the production cost can be reduced, and the method is particularly suitable for small-batch machining.

Description

technical field [0001] The invention belongs to the technical field of precision machining and relates to a three-axis digital milling method for small-sized blades. Background technique [0002] Blades are a very important type of parts in industrial manufacturing and play a key role in the performance of products. Product efficiency, service life and other indicators are directly affected by the design and manufacturing quality of the blades, and are the main influences. In particular, the blades in the field of precision machining are very important to the performance of the product, because most of the blades in this field are irregular in shape, and the size calculation is complicated, which is very different from ordinary parts. [0003] At present, for blades, especially for small-sized blades with a blade body length of less than 30 mm and a blade chord width of about 20 mm, its manufacturing is mainly realized through the following process: 1) In the blank manufact...
