Abstract

The main goal of this research is to compare the various optimization strategies (Response Surface Methodology, Taguchi, and Teaching Learning Based Optimization) for orthogonal turning of Hard to Machine materials. The workpiece material in this work is Ti6Al4V alloys. After selecting cutting speeds in the High-Speed Machining range, orthogonal turning tests are performed on the material for a specific combination of machining parameters – Depth of Cut, Cutting Speed, and, Feed Rate. A Lathe Tool Dynamometer is used to record the cutting forces from the trials. After combining Johnson Cook Material and Damage models, a comprehensive Finite Element Model is created to model the Orthogonal Turning of Ti6Al4V alloys. Experiments conducted previously validate the developed model. Three different strategies, namely RSM, Taguchi, and TLBO, were used to optimise machining parameters for minimal Cutting Force. The approaches are compared for the best combination of machining parameters and the best Cutting Force value. Analysis of Variance is used to study the impact of machining factors on Cutting Force.

Ti6Al4V合金正交车削优化及有限元建模:不同优化技术的比较研究

本研究的主要目的是比较难加工材料正交车削的各种优化策略(响应面法、田口法和基于教学学习的优化)。本工作的工件材料为Ti6Al4V合金。在高速加工范围内选择切削速度后，根据切削深度、切削速度和进给速度等特定加工参数组合，对材料进行正交车削试验。车床工具测功仪用于记录试验的切削力。结合Johnson Cook材料模型和损伤模型，建立了Ti6Al4V合金正交车削的综合有限元模型。先前进行的实验验证了所开发的模型。采用三种不同的策略，即RSM、田口和TLBO来优化加工参数，以实现最小切削力。比较了两种方法的最佳加工参数组合和最佳切削力值。采用方差分析方法研究了加工因素对切削力的影响。

期刊介绍： Engineering Solid Mechanics (ESM) is an online international journal for publishing high quality peer reviewed papers in the field of theoretical and applied solid mechanics. The primary focus is to exchange ideas about investigating behavior and properties of engineering materials (such as metals, composites, ceramics, polymers, FGMs, rocks and concretes, asphalt mixtures, bio and nano materials) and their mechanical characterization (including strength and deformation behavior, fatigue and fracture, stress measurements, etc.) through experimental, theoretical and numerical research studies. Researchers and practitioners (from deferent areas such as mechanical and manufacturing, aerospace, railway, bio-mechanics, civil and mining, materials and metallurgy, oil, gas and petroleum industries, pipeline, marine and offshore sectors) are encouraged to submit their original, unpublished contributions.
