Elektro Erozyon ile Delik Delmede İşlemenin İşparçası Yüzey Karakteristiklerine Etkisi
Elektro erozyon ile delik delmede (EEDD), işparçası yüzeyinin elektriksel boşalmalar yoluyla hızlı bir şekilde bölgesel olarak ısıtılması ve soğutulması, yüzey katmanlarına (tekrardan katılaşmış, ısıl etkilenmiş ve ana malzeme) neden olur. Bu çalışmada, ana işparçası yüzey dokusu, yani tekrardan katılaşmış katman kalınlığı (RLT) ve ortalama yüzey pürüzlülüğü (Ra) özellikleri, farklı işleme parametreleri için (boşalım akımı ve vurum süresi) araştırılmıştır. Yapılan deneyler, yüzey özelliklerinin işleme parametrelerine kuvvetle bağımlılığını ortaya koymuştur.
Effect of Machining on Workpiece Surface Characteristics in Electric Discharge Drilling (EDD)
In electric discharge drilling (EDD), rapid local heating and cooling of the workpiece surface by means of electric discharges results insurface layers (recast, heat affected and base material). In this study, the main workpiece surface texture measures, namely the recast layerthickness (RLT) and average surface roughness (Ra) characteristics were investigated for varying machining parameters (discharge currentand pulse on time). The conducted experiments revealed the strong dependence of surface characteristics on machining parameters.
