Embodiment 1

[0052] In a typical embodiment of the present invention, such as Figure 1-15 As shown, a verification method for the machining process of turbine disc parts is proposed, including the following steps:

[0053] The verification methods of processing technology are divided into three levels: material processability verification, feature processability verification and part processability verification.

[0054] Among them, the first level is the material processability verification, which includes a large number of physical tests and appropriate simulation verification, to study the processing performance of the turbine disk material and the integrity of the processed surface, to establish a simulation program for the study of material processability and to verify its feasibility Performance evaluation indicators mainly include cutting force during cutting, cutting temperature and roughness of machined surface, microhardness of machined surface, microstructure of machined surfac...

Abstract

The invention discloses a verification method of a turbine disc part machining process, relates to the technical field of machining and solves the problem that an optimal machining scheme and machining parameters can be determined only by researching and optimizing a heat treatment mode, a machining process, a process route and used cutters through a large number of physical tests, thereby reducing the test cost. According to the specific scheme, the method comprises the following steps: carrying out part material machining performance verification test, and simulating part machining performance; comparing machining performance simulation data with test data to test the feasibility of a part material machining performance simulation scheme; simulating the part feature machinability, and testing the feasibility of a feature machinability simulation scheme through a test; and carrying out modeling after a simplified part is reconstructed through machining features, simulating the part machining process, and optimizing the machining technology of the part according to comparison of machining process simulation data and technical requirements.

Description

technical field [0001] The invention relates to the field of mechanical processing, in particular to a method for verifying the processing technology of turbine disk parts. Background technique [0002] The statements herein merely provide background information related to the present invention and do not necessarily constitute prior art. [0003] Disk parts have complex structures and processing techniques. Turbine disks are important components in aero-engines and are large-scale and typical thin-walled rotating parts. The cross-section of turbine disks has a large diameter outer rim, which is thin and rigid Poor, easily deformed. [0004] In addition to thin-walled features, there are many other complex machining features on the turbine disk, including arcs, tenons, and cavities. The inner cavity is large and the outer is small, and the opening is poor. Large, large structural size, poor tool accessibility, serious processing deformation; more arcs on the inner cavity s...
