This paper discusses the comparison of MRR for EN19 and EN41 materials machine.
Different input factors such as pulse ON time, pulse OFF time, discharge current, and voltage
were as input processing parameters, and MRR is calculated as the output. Using Optimization
The Taguchi method was used to predict the best combination leading to the highest yield.
Comparison these input parameters were implemented for both material and simultaneously to
obtain the effect on MRR investigated the effect of carbon percentage on MRR. It was found
that: The EN41 material and the EN19 material had a greater effect on the MRR compared to
the other operating parameters. A as well as a comparative study of the carbon composition of
both materials.
In this paper, the effect and optimization of eight control factors on material removal rate
(MRR), surface roughness, and bonding are reported. The experiment is carried out under
different cutting conditions of wire feed rate, dielectric pressure, pulse duration, pulse idle time,
open voltage, wire tension, and servo voltage by varying the material thickness. The Taguchi
L18 orthogonal array is used for the experimental design. Analysis of variance (ANOVA) and
signal-to-noise (S/N) ratio are used as statistical analyzes to identify significant control factors
and achieve optimal levels. In addition, linear regression and additional models were developed
for surface roughness, surface area, and material removal rate (MRR). The results of the
validation experiments were found to be in good agreement with the predictions. Pulse duration
was found to be the most significant factoraffecting surface roughness, surface coverage, and
material removal rate.
EN41 steel, also known as standards 905M39, is a chromium-aluminum-molybdenum alloy
nitrogen steel designed to deliver high performance in applications requiring high wear,
strength, and fatigue strength. This material is widely used in applications ranging from the
automotive to aerospace and textile industries due to its excellent abrasive wear resistance and
ability to withstand high stress conditions. Despite its widespread use, the optimization of the
properties of EN41 through controlled manufacturing processes and advanced heat treatment
techniques remains an area that requires significant research attention.
This paper provides an in-depth analysis of the chemical composition, heat treatment methods,
microstructural changes, and mechanical properties of EN41 steel. Particular attention is paid
to the benefits and challenges of nitriding, which is an enhanced surface finish that increases
surface hardness and wear resistance while maintaining core ductility.
