specific example

[0031] The parts processed in the test are aerospace titanium alloy thin-walled parts. The OPTICUT software of Beijing University of Aeronautics and Astronautics is used to select the cutting parameters, and the UG software is used to design the CAM program and process equipment. The KPU4000 produced in Spain is used as the processing equipment, and the tool size is 20mm. The cutting depth is 1mm, the cutting width is 12mm, the speed is 900r / min, and the feed is 400mm / min. The structure of part 1 is a casting cabin.

[0032] The main process design process is as follows: design rigidity strengthening tooling such as figure 1 As shown, adjust the clamping position according to the size of part 1. Use the CAM software to generate the profiling processing program for the bottom surface of the flat-bottomed knife, and use the chatter analysis software to perform chatter analysis. figure 2 As shown, a circular insert tool is selected, and the circular blade of the tool is used f...

Abstract

The invention discloses a machining method of a thin-wall heterogenic titanium alloy part. The part is clamped by a rigidity reinforced tool in an internal and external opposite pushing manner, and placed on a base of the rigidity reinforced tool, a machining position of the part is clamped by the rigidity reinforced tool in an external opposite pushing manner, and the interior of the part adopts a main beam of the rigidity reinforced tool as a force transmission device. The method aims at improving the rigidity of the part to be machined, and the rigidity reinforced tool is designed to reinforce supporting and improve the body rigidity of the part. For the selection of machining parameters of titanium alloy, the entire oscillation stability domain analysis based on cutter part equipment is adopted, and appropriate cutting parameters are selected; for a shape forming method of the cut part, the cutter base plane modeling is adopted; a cutting tool adopts a circular inserted cutter; the strength of the cutter is improved; a cutting angle is controlled by a cutting depth; and a cutting force and cutting heat are reduced.

Description

technical field [0001] The invention belongs to the technical field of mechanical processing, and relates to a processing method for thin-walled special-shaped titanium alloy parts. Background technique [0002] Because of the characteristics of light weight, material saving, and compact structure, thin-walled parts have been increasingly widely used in various industrial sectors. As a material with high specific strength, titanium alloy has become the material choice for thin-walled parts. However, titanium alloy materials have large cutting force, low thermal conductivity, and severe work hardening; thin-walled parts have poor rigidity and weak strength, and are easily deformed during processing, which makes it difficult to guarantee the processing quality of parts. These unique properties determine that machining must be optimized in terms of cutting tools, parameter selection, and process equipment design. [0003] At present, there are many processing and clamping met...
