Abstract

Surface finish and temperature rise are the crucial machining outcomes since it determines the quality of the machining and the tool life. During machining operations, choosing optimal machining parameters is critical since it affects the machining outcome. In this work, Multi-Objective Genetic Algorithm (MOGA) optimization is used to find the combination of machining parameters at different levels of hardness of 20, 36, and 43 to obtain minimum surface roughness and minimum cutting temperature in turning operation. Cutting depth, cutting speed, and feed rate are the machining variables that are used in the process of optimization. From the results, it shows that the minimum temperature rise is 243.333 ℃ with a surface roughness of 1.975 μm during machining of 20 hardness. It also observed that the hardness of the material significantly affects the surface roughness and temperature rise. The outcome shows that as the hardness of the material is increasing the temperature is increasing while the surface roughness is decreasing. This research also revealed that using a MOGA to optimize multi-objective replies produces positive outcomes.

基于多目标遗传算法的不同硬度车削加工参数优化

表面光洁度和温升是关键的加工结果，因为它决定了加工质量和刀具寿命。在加工过程中，选择最优的加工参数是影响加工效果的关键。本文采用多目标遗传算法(MOGA)优化，寻找20、36和43不同硬度下的加工参数组合，以获得车削加工中最小的表面粗糙度和最小的切削温度。切削深度、切削速度和进给速度是优化过程中使用的加工变量。结果表明:当加工硬度为20时，最小温升为243.333℃，表面粗糙度为1.975 μm;还观察到材料的硬度对表面粗糙度和温升有显著影响。结果表明，随着材料硬度的增加，温度升高，表面粗糙度减小。本研究还发现，使用多目标遗传算法来优化多目标回复会产生积极的结果。
