Parametric optimization of WEDM in machining HSS (8X200)‎

Abstract EN

Nontraditional machining processes are used for machining too hard, brittle and strong conductive materials.

The aim of this research is to achieve an economic and efficient machining process in machining HSS by using wire cut machine.

Experimental investigations were conducted on WEDM with using different machining parameters such as (pulse duration (μs), pulse interval (μs), Servo feed and Servo voltage (V)).

The experiments were designed according to DOE, which is done by using Taguchi design parameter method to investigate the optimum machining parameters, which gives the best values for MRR and CS in order to achieve an economic and efficient machining process.

The results obtained from the experimental work show that the optimum values of MRR and CS are obtained with the best values of Servo voltage (V), pulse duration (μs), pulse interval (μs), Servo feed and which they are presented with (A1, B3, C2 and D3) which they are equal to (20 v, 120 μs, 35 μs, and 450 mm/min).
