Abstract

Nickel-based superalloys owes strong high temperature strength and corrosion resistance, and are widely used in aerospace and other fields. Machining of nickel-based superalloy is a typical thermal-mechanical coupling process. A prediction model of cutting force and cutting temperature was established for a orthogonal cutting, and the coupling stress of the cutting force and cutting heat was calculated. The orthogonal cutting experiment of GH4169 was conducted with cermet cutting tool. The cutting force and cutting temperature of prediction model was verified. And the distribution of stress on the rack face and wear of cutting tool were analyzed under different cutting parameters. The wear of cutting tool in the cutting process was mainly the crater wear on the rake face. The wear mechanism of the cutting tool and the wear amount of the crater on the rake face were analyzed based on thermal-mechanical coupling. The research results can provide a theoretical basis for optimizing the design and manufacture of cutting tools and improving the wear resistance of cutting tools.

镍基超合金 GH4169 与金属陶瓷切削刀具高速切削磨损机理的热机械耦合效应研究

镍基超级合金具有很强的高温强度和耐腐蚀性，被广泛应用于航空航天等领域。镍基超合金的机加工是典型的热-机耦合过程。本文建立了正交切削的切削力和切削温度预测模型，并计算了切削力和切削热的耦合应力。使用金属陶瓷刀具对 GH4169 进行了正交切削实验。验证了预测模型的切削力和切削温度。并分析了不同切削参数下齿条表面的应力分布和刀具磨损情况。切削过程中刀具的磨损主要是齿条面上的凹坑磨损。基于热机耦合分析了切削刀具的磨损机理和耙面凹坑的磨损量。研究成果可为优化切削工具的设计和制造、提高切削工具的耐磨性提供理论依据。

期刊介绍： Manufacturing industries throughout the world are changing very rapidly. New concepts and methods are being developed and exploited to enable efficient and effective manufacturing. Existing manufacturing processes are being improved to meet the requirements of lean and agile manufacturing. The aim of the Journal of Engineering Manufacture is to provide a focus for these developments in engineering manufacture by publishing original papers and review papers covering technological and scientific research, developments and management implementation in manufacturing. This journal is also peer reviewed. Contributions are welcomed in the broad areas of manufacturing processes, manufacturing technology and factory automation, digital manufacturing, design and manufacturing systems including management relevant to engineering manufacture. Of particular interest at the present time would be papers concerned with digital manufacturing, metrology enabled manufacturing, smart factory, additive manufacturing and composites as well as specialist manufacturing fields like nanotechnology, sustainable & clean manufacturing and bio-manufacturing. Articles may be Research Papers, Reviews, Technical Notes, or Short Communications.
