Abstract

In today’s competitive modern manufacturing sectors, there is a vital need of utter precision and rigorous processing using various manufacturing approaches that directly influences the cost and processing duration of mechanized materials in addition to the consistency of the finished products. Therefore, it’s essential to figure out the required output by adjusting the control factors of any machining techniques which resulted in optimal values of the desired outcome. In this study, machining evaluation and process optimization is carried out on volumetric extraction of material namely material removal rate (MRR), kerf obtained during the machining (KW) and surface roughness (SR) of Inconel 718 superalloy during CNC controlled wire- electrical discharge machining. Four controllable factors- pulse interval, wire speed, pulse duration and peak current are considered to investigate the influence on performance measures. Taguchi's L16 has been used to construct the set of experiments before physical experimental runs and most influencing factors have been evaluated using ANOVA. SEM images and EDXS analysis have been resorted to examine the morphology of Inconel 718. These findings assist in identifying the topography of the machined surface. Further, the optimum integration has been obtained for the best yield and recorded using grey relational analysis integrated with Taguchi’s technique (T-GRA). The unfamiliarity of the work is based on consideration of zinc coated thin wire electrode and Taguchi-Grey combined approach of modelling with four levels of experimental design.
用T-GRA法分析Inconel 718合金电火花加工的控制因素和表面完整性
在当今竞争激烈的现代制造业中,除了成品的一致性外,还需要使用各种制造方法进行绝对精确和严格的加工,这直接影响到机械化材料的成本和加工时间。因此,必须通过调整任何加工技术的控制因素来确定所需的输出,从而使期望的结果达到最优值。在本研究中,对数控线切割加工中Inconel 718高温合金的材料体积提取,即材料去除率(MRR)、加工时获得的切口(KW)和表面粗糙度(SR)进行了加工评价和工艺优化。考虑了脉冲间隔、导线速度、脉冲持续时间和峰值电流四个可控因素对性能指标的影响。在物理实验运行之前,我们使用田口L16来构建实验集,并使用方差分析评估了大多数影响因素。利用SEM图像和EDXS分析来检查Inconel 718的形貌。这些发现有助于识别加工表面的形貌。在此基础上,利用灰色关联分析与田口技术(T-GRA)相结合的方法,确定了最佳产量的最佳积分。工作的不熟悉性是基于考虑锌涂细丝电极和田口-格雷联合建模方法与四个层次的实验设计。
