Summary: Traditional cutting fluids (CFs), which are essential for metal working operations, are often based on mineral oils or water-based formulations containing mineral oils. However, these CFs can become contaminated over time, leading to negative impacts on the environment and human health, and are costly to dispose of. In order to address these issues, the development of greener, more sustainable CFs using microbial-based lubricant components is being explored. Research has shown that replacing mineral oil with suitable microorganisms in CFs can significantly reduce the negative effects of traditional CFs on the environment and human health, while maintaining comparable or better cutting performance.

Summary: Traditional cutting fluids are potentially harmful to humans and the environment due to contamination and use of biocides. This study explores the replacement of mineral oil in cutting fluids with microbial-based lubricants to reduce these negative impacts. The use of microbial-based cutting fluids showed comparable or better performance in cutting forces, tool wear, surface finish, and dimensional accuracy compared to dry cutting and conventional fluids.

Summary: In recent years, there has been an increasing demand for materials that can withstand high and/or low temperatures and harsh conditions. Superalloys have superior qualities that can meet this demand. However, the difficulties in machining these alloys pose ecological and economic burdens due to the use of cutting fluid. Therefore, using cost-friendly and sustainable cutting fluids is important in terms of machining performance and the environment. This study focuses on the effects of various cutting environments on the machining performance of Ni-based C4 alloy and analyzes their sustainability. The results show that the combination of Vortex and MQL cutting condition has the best performance in terms of surface roughness and power consumption, while LN2 has the best performance in terms of cutting temperature.

Summary: High heat generation in machining processes affects tool life and workpiece quality. Conventional cutting fluid cooling has environmental hazards and high manufacturing costs. This study evaluates the performance of a novel internally cooled tool for machining grey cast iron, which effectively removes heat from the interface. The results show that the internally cooled tool reduces surface roughness and increases microhardness and machining performance, indicating its potential as an eco-friendly and efficient technique.

Summary: The impact of cutting-edge microgeometry on cutting forces in the finish milling of a 7075-aluminium alloy was analyzed. The influence of rounding radius of cutting edge and the size of the margin width on cutting-force parameters was analyzed. Experimental tests were carried out for different cross-sectional values of the cutting layer. Mathematical models of the relationship between force parameters and the radius of the rounded cutting edge and the width of the margin were developed.

Summary: This study discusses the milling of Nickel-Titanium (NiTi) alloy and evaluates the effect of various parameters on the surface roughness. The results indicate that a CVD-coated cutting tool, -196°C cryogenic heat treatment, EG+5%BX cutting fluid, 50 m/min cutting speed, and 0.03 mm/tooth feed are the optimal parameters for achieving a lower surface roughness.

Summary: Conventional cutting fluids used in manufacturing industries are toxic and harmful to humans and the environment. Non-edible oils, such as castor oil and Karanja oil, can be used as a green alternative. Water-soluble cutting fluids formulated from these non-edible oils and food-grade surfactants show improved performance in steel machining, reducing cutting force, surface roughness, and tool wear compared to conventional mineral oil-based cutting fluids. These developed cutting fluids are safe for humans and the environment, suggesting the use of non-edible oil-based cutting fluids as an alternative to mineral oil-based ones.

Summary: This study employs a hybrid optimisation technique combining artificial neural network and response surface methodology models to predict the microstructural and mechanical characteristics of LPBF manufactured maraging steel 1.2709 parts. The results show that the artificial neural network model has better prediction accuracy compared to the response surface methodology model. The most desirable optimal LPBF processing parameters were found to be at a volumetric energy density of 77 J/mm3.
