Abstract

The invention belongs to the technical field of precision machining, and discloses a three-axis digital milling method for small-sized blades. The three-axis digital milling method for small-sized blades provided by the present invention uses three-axis digital milling when manufacturing the blades: firstly, the surface of the blade basin is milled, and secondly, the back of the blade is processed. However, when processing the back of the blade, because the surface of the blade basin has been processed , coupled with the small thickness of the blade body, it is easy to cause the blade surface to be deformed by the cutting force, making the product quality unqualified. In addition, it is easy to gnaw the surface of the blade during processing, and it is difficult to meet the requirements for surface accuracy. In order to solve this deformation problem, when processing the back of the blade, the auxiliary alloy lower than the melting point of the processing material is filled in the cavity of the blade pot, which will not bring quality problems to the blade itself. After the auxiliary alloy is solidified and crystallized, and the back of the leaf is processed, the auxiliary alloy is removed by heating. The processing method provided by the invention is simple, high in efficiency, and has low requirements on equipment, thereby reducing the production cost and being especially suitable for processing in small batches.

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...
