Abstract

In this study the microstructure and surface roughness of AISI D5 steel were investigated according to process parameters in the wire electro-discharge machining (WEDM). In the experiments, puls on time, voltage, dielectric fluid circulation pressure and wire feed rate were taken as variables. After cutting operations, the microstructure of the specimens were examined by optical and SEM microscopy and the microhardness and surface roughness were measured. As a result, the properties of the surfaces were observed to be dependent upon the process parameters and it was concluded that in WEDM the process parameters should be selected according to the desired properties of the material.

Özet

Bu çalışmada, tel erozyon yöntemiyle farklı şartlarda kesilen AISI D5 takım çeliğinin ısıl işlem görmüş ve ısıl işlem görmemiş durumlardaki mikroyapısı ve yüzey pürüzlülüğü incelenmiştir. Deneylerde puls süresi, gerilim, dielektrik sıvı sirkülasyon basıncı ve tel ilerleme hızı değişken olarak alınmıştır. Kesme işlemi sonrasında numunelerin mikrosertlikleri ve yüzey pürüzlülükleri ölçülmüş, mikroyapısal değişimler optik ve taramalı elektron mikroskobunda (SEM) incelenmiştir. Sonuç olarak, parametre seçiminine bağlı olarak yüzey özelliklerinin değiştiği ve işlem parametrelerinin malzemeden beklenen özelliklere göre seçilmesi gerektiği ortaya konulmuştur.
