“…Response Surface Methodology (RSM) is a collection of mathematical, and statistical techniques useful for the modelling, and analysis of problems in which a response of interest is influenced by several variables, and the objective is to optimize this response [33][34][35]. There is a loss in productivity, and quality due to wire breakage.…”

Wire electrical discharge machining (WEDM) technology is a special electrothermal processing method that can precisely production of parts with variable stiffness with sharp edges or production of complex geometric parts which are difficult to produce by traditional manufacturing methods. It has an important place in production sector in terms of low energy consumption. In this study, the relationship between processing parameters on surface quality on the ferritic ductile cast iron (GGG-40) material in WEDM process with molybdenum wire was investigated by Response Surface Methodology (RSM). The aim of this study is to determine the optimum process parameters for low-cost production of GGG-40 material with sharp-edged and complex geometry parts using the WEDM method. In experimental works, surface roughness, and process time were investigated using table feedrate, pulse on time, and pulse space as cutting parameters. The surfaces obtained as a result of the experiments were evaluated in terms of surface quality with Scanning Electron Microscopy (SEM), and surface roughness device. According to the findings, it has been observed that the surface roughness has increased with increasing table feedrate, and pulse on time, and surface roughness decreased with pulse space increasing. Also, it is understood that pulse on time is the most important factor effecting surface quality. It has be en found that the process time depends on only the table federate where they are inversely proportional. As result of RSM analysis, optimum cutting parameters were obtained in terms of lowest surface roughness, lowest process time and best time/performance condition on both parameters for ferritic ductile cast iron in WEDM process.

This article examines energy consumption, microstructure, mechanical properties, and the change in the wear amount during the machining of GGG-42 cast iron material with two types of guide cutting tool produced by powder metallurgy and casting method The tap. tool samples used as cutting tool material were first subjected to the traditional hardening process and then to two different cryogenic treatments (24–16 h) at −90°C. The internal structures of the guide samples obtained from conventional heat treatment and cryogenic treatment were examined with an optical microscope and Scanning Electron Microscope. The hardness changes were checked with Vickers measurement method. The wear amount forming after the threading process was measured with CLEMEX program in a light microscope. In addition, by measuring the current amount drawn during the machining of the cast iron with guide cutter tools, instantaneous power consumption during cutting and power consumption during chip removal were calculated. The application of heat treatment and cryogenic process increased the hardness of the guides. Moreover, the power consumption during the chip removal was also seen to increase. This can be commented that cutting tools produced with powder metallurgy perform better than the cutting tools produced via casting and 30% energy saving.

Pumps in fuel oil systems are mechanical equipment used for the transfer of liquid fluid from one place to another. In particular, pumps are required to transfer the maximum flow rate in the transfer units in minimum time. They consume a very high amount of energy for this transfer. In this research, research studies were carried out to ensure the transfer of the highest possible amount of fuel oil by consuming energy at optimal rates. In this experimental study, the energy consumption and flow rate were measured across a range of engine speeds (100-700 RPM) and varying gear lengths (90-100 mm). According to the findings, energy consumption reached ideal levels at 600 RPM engine speed. In addition, it was determined that the lowest CO2 emission was obtained in the range of 600-700 RPM and by using long gear length. In addition, it is observed that the effect of gear length on energy efficiency is significant and energy consumption decreases as the gear length gets shorter. The results show that minimum energy consumption can be obtained with maximum flow rate at 609 RPM engine speed and 100 mm gear length. The ANOVA analysis used in the study reveals that the flow rate changes are 98% related to the engine speed, while the gear length is 78% effective in CO2 emission reduction. This research provides an important contribution to energy efficiency and carbon emission reduction in industrial applications. This study provides an innovative method that can be used to achieve energy saving and environmental sustainability goals and makes valuable contributions to the literature on optimising internal gear pump designs.
