TY - JOUR ID - TI - Investigation theElectrode Wear Rate and Metal Removal Rate in EDM Process using Taguchi and ANOVA Method AU - Safaa K. Ghazi PY - 2020 VL - 38 IS - 10 part (A) Engineering SP - 1504 EP - 1510 JO - Engineering and Technology Journal مجلة الهندسة والتكنولوجيا SN - 16816900 24120758 AB - The experimental work of this paper leads toelectricaldischarge machining (EDM). A system for machining in this process has been developed. Many parameters are studied such as current, pulse on-time, pulse off time ofthe machine. The main aim of this work is to calculate the metal removal rate (MRR) and electrode wear rate (EWR) using copper, electrodes when machining tool steel H13 specimens of a thickness (4mm). Different current rates are used ranging from (30, 42,and 54) Amp, pulse on-time ranging from (75, 100,and 125) and pulse off time ranging from (25, 50,and 75) found that high current gives large electrode wear and metal removal rate and. The experiment design was by Taguchi Method. From an analysis of variance (ANOVA) themore active influence of input factors on the outputs is currentlyfor metal removal rate (MRR) (58%) and electrode wear rate (EWR) (57).
