Trans-scale design method of high-speed milling cutter and milling cutter

Abstract

The invention discloses a trans-scale design method of a high-speed milling cutter and the milling cutter. At present, the research of the internal relation among a microstructure, a macrostructure and performance of cutter materials is absent, and scientific evidences of the design and the development of the novel high-speed milling cutter are absent. The method comprises the following steps of: (1) constructing a high-speed milling cutter safety decline behavioral characteristic model; (2) developing the high-speed milling cutter by using a high-speed milling cutter safety stability design model; (3) establishing a high-speed milling cutter safety decline behavioral characteristic model design matrix by a grey correlation analysis method to characterize the relation between milling cutter design parameters and safety decline; (4) establishing a high-speed milling cutter mesoscopic level safety model by a grey cluster analysis method; and (5) researching macroscopic and mesoscopic mechanical characteristics of a high-speed milling cutter component under the condition of presetting an external force boundary, and realizing force connection-based high-speed milling cutter trans-scale correlation through continuous medium-molecular dynamic characteristic zigzag mapping. The method is used for designing the high-speed milling cutter.

Description

Technical field: [0001] The invention relates to a high-speed milling cutter and a design method thereof, in particular to a mapping transformation and cross-scale correlation design method among the safety mesoscopic structural domain, macroscopic structural domain and functional domain of the high-speed milling cutter. Background technique: [0002] In terms of high-speed milling cutter design and safety evaluation, due to the existence of internal and external disturbance factors and the limitation of cognitive level, the obtained information is fuzzy and uncertain. [0003] The safety degradation of high-speed milling cutter is the evolution process from microstructure change and microdefect nucleation to macroscale change and deformation defect formation under the interaction and coupling of nonlinear multi-strong fields, until fracture occurs. At present, due to the lack of research on the internal relationship between the microstructure, macrostructure and performance...

AI Technical Summary

Problems solved by technology

At present, due to the lack of research on the internal relationship between the microstructure and macrostructure and performance of tool materials, and the fact that their evolution behavior under the action of multiple strong fields cannot be quantitatively described, the design and development of new high-speed milling cutters lack scientific basis.
