Abstract:

“Baru-baru ini, kemudahan permesinan benda kerja menggunakan proses ElectricalDischarge Machine (EDM) telah ditentukan oleh teori ?·?·?. Berdasarkan teori ?·?·?kemudahan proses EDM ditentukan oleh konduktivitas termal (?), temperatur titik leleh (?),dan tahanan listrik sebuah material (?). Keuntungan menggunakan permesinan EDM adalahketidakbergantungnya kekerasan sebuah material benda kerja untuk diproses. Namun dariteori ?·?·? dibutuhkan energy yang berbeda untuk memproses 12 jenis material bendakerja. Studi kasus dari penelitian ini adalah menganalisa secara dimensional TeoremaBuckingham ? hubungan antara teori ?·?·? dengan sifat fisik kekerasan sebuah material.Proses EDM tidak terlepas dari efek akibat adanya pemberian tegangan dan kapasitansiyang akibat proses ini terjadinya ionisasi yang menimbulkan stokastik termal. Performasebuah material dikaitkan dengan titik leleh material tersebut. Pada saat titik leleh sebuahmaterial tercapai maka akan ada gerakan atom, dimana akan menimbulkan dislokasi dantegangan sisa pada material tersebut. Hasil menunjukkan bahwa ada koefisien korelasipositif antara kekerasan dengan teori ?·?·? dalam menentukan kemudahan proses EDMdan dengan menggunakan Teorema Buckingham ? didapat formula matematika hubungankekerasan dengan teori ?·?·?.Kata kunci: electrical discharge machining; Buckingham ?; teori ?·?·?, kekerasanMore recently, the easy of machining the work piece using the Electrical Discharge Machine(EDM) has been determined by the theory of ? • ? • ?.
