Wire electrical discharge machining (WEDM), havacılık, kalıp ve kalıp yapımı, otomobil endüstrileri ve biyomedikal alanda karmaşık ve zorlu şekillerdeki iletken malzemelerin işlenmesi için yaygın olarak kullanılan bir işleme yöntemdir. WEDM Ürün kalitesinden ödün vermeden güç tüketimini en aza indirmek için üretim sektöründe önemli bir yere sahiptir. Bu doğrultuda, mevcut araştırma, WEDM parametrelerinin sürdürülebilirlik için yüzey pürüzlülüğü, kerf genişliği ve çevresel kaygı için güç tüketimi güç tüketimi ile ilişkisi Response Surface Methodology (RSM) ile araştırılmıştır. Deneysel araştırmalar için, 0,18 mm Guangming Molibden alaşım tel kullanılarak Feed rate, pulse width, pulse space ve wire speed gibi işleme parametreleri seçilmiştir. RSM, deneyleri tasarlamak ve yüzey pürüzlülüğünü, güç tüketimini ve kerf genişliğini en aza indirmek için WEDM'nin bağımsız parametrelerini analiz etmek ve optimize etmek için kullanılmıştır. Deneyler sonucunda optimum üretim parametreleri belirlendi. Varyans analizinden (ANOVA) önemli proses parametreleri belirlendi. Ayrıca, optimum proses parametrelerinin performansını doğrulamak için doğrulama deneyi yapılmış ve deneysel değerlerle iyi bir uyum içinde olduğu kaydedilmiştir. Sonuç olarak, yüzey pürüzlülüğü, kesme gücü ve kerf genişliği üzerindeki en etkin parametreler sırasıyla %67,96 oranla pulse width, 54,96 oranla wire speed, %63,65 oranla pulse width olduğu anlaşılmıştır.

RSM-based measurement of cutting performance on Al 7075 T6 aero-structural alloy using WEDM

Öz

Wire electrical discharge machining (WEDM) is a machining method commonly used in the aerospace, die making, automotive, and biomedical fields for machining complex and challenging shapes of conductive materials. WEDM is used in manufacturing to reduce power consumption while maintaining product quality. The current study used Response Surface Methodology (RSM) to investigate the relationship of WEDM parameters with surface roughness, kerf width, and power consumption for environmental concerns. Cutting parameters such as feed rate, pulse width, pulse space, and wire speed were chosen for experimental studies using 0.18 mm Guangming Molybdenum alloy wire. RSM was used to design experiments, analyze, and optimize WEDM independent parameters to minimize surface roughness, power consumption, and kerf width. The experiments yielded optimal cutting parameters. Analysis of variance (ANOVA) was used to determine important cutting parameters. Furthermore, a validation experiment was carried out to verify the performance of the optimum cutting parameters, which were found to be in good agreement with the experimental values. As a result, the most effective parameters for surface roughness, cutting power, and kerf width were discovered to be pulse width (67.96%), wire speed (54.96%), and pulse width (63.65%), respectively.
