ABSTRACT Electrical Discharge Machining (EDM) is one of the most important and popular technologies in the world today [1, 5], applyingin machining the hard materials with heat treatment in the mold manufacturing industry. Optimization of technology parameters receives the attention of experts in the EDM field. This paper presents the material removal rate (MRR) optimization by Taguchi method with 4 input technology parameters: amperage (I); discharge gap voltage (U); discharge on time (Ton); discharge off time (Toff), one output parameter is material removal rate (MRR). Orthogonal matrix L25 in Taguchi method was used to design the experiment. The results showed that, the optimal parameter of SKD11 steel processing single-goal problem in EDM is I = 5A; Ton = 18µs, Toff = 37µs; U = 60V significantly reduces the time and cost of doing the experiment. Keywords: EDM, SKD11 toolsteel, material removal rate. |
