Optimization of Machining Parameters of Al2024-T3 Material Machined With Electro Discharge Machining

Abstract

Aluminum alloys are widely used in the aviation, automotive and defense industries today due to their lightness, high strength and economical nature. In this study, by using the electro discharge machining in the machining of Al2024-T3 material, performance responses were obtained based on the material removal rate (TKM), tool wear rate (TAM) and average surface roughness (Ra) data. In the experiments, the effects of discharge current (Ip), pulse duration (Ton) and pulse interval (Toff) parameters were examined. As a result of the analysis of variance (ANOVA), it was determined that the effective parameters on the experimental results were Ton, Ip and Toff, respectively. In the study, models were used to optimize the experimental results and the machining parameters that would achieve optimum results were determined.

Elektro Erozyon Yöntemi ile İşlenen Al2024-T3 Malzemesinin İşleme Parametrelerinin Optimizasyonu

Öz

Günümüzde alüminyum alaşımları hafif olması, yüksek dayanım sunması ve ekonomik olmaları gibi sebeplerle havacılık, otomotiv ve savunma sanayiinde yoğun olarak kullanılmaktadır. Bu çalışmada Al2024-T3 malzemesinin işlenmesinde elektro erozyon yöntemi kullanılarak, talaş kaldırma miktarı (TKM), takım aşınma miktarı (TAM) ve ortalama yüzey pürüzlülüğü (Ra) olarak sıralanabilecek performans yanıtları üzerinden sonuçlar elde edilmiştir. Yapılan deneylerde boşalım akımı (Ip), vurum süresi (Ton) ve vurum aralığı (Toff) parametrelerinin performans yanıtları üzerindeki etkileri incelenmiştir. Yapılan varyans analizi (ANOVA) sonucunda deney sonuçları üzerinde etkin parametrelerin sırasıyla Ton, Ip ve Toff olduğu tespit edilmiştir. Çalışmanın devamında performans yanıtlarını eniyileyecek parametre değerlerinin tespiti amacıyla bir optimizasyon çalışmasına da yer verilmiştir.
