“…In the subsequent experiments, scholars mixed Al 2 O 3 and graphite to prepare hybrid nano-enhanced biolubricants, and the grinding performance was improved, which is due to the different tribological mechanism of the two types of nano-enhancers. The layered structure of graphene oxide allows easy access to the sliding zone and reduces the direct contact between particle with the metal, [133]. The wheel wear degree depends on the thermal/force boundary conditions in the grinding zone: ① The lack of lubrication ability under flood results in the aggravation of abrasive wear.…”

The substitution of biolubricant for mineral cutting fluids in aerospace material grinding is an inevitable development direction, under the requirements of the worldwide carbon emission strategy. However, serious tool wear and workpiece damage in difficult-to-machine material grinding challenges the availability of using biolubricants via minimum quantity lubrication. The primary cause for this condition is the unknown and complex influencing mechanisms of the biolubricant physicochemical properties on grindability. In this review, a comparative assessment of grindability is performed using titanium alloy, nickel-based alloy, and high-strength steel. Firstly, this work considers the physicochemical properties as the main factors, and the antifriction and heat dissipation behaviours of biolubricant in a high temperature and pressure interface are comprehensively analysed. Secondly, the comparative assessment of force, temperature, wheel wear and workpiece surface for titanium alloy, nickel-based alloy, and high-strength steel confirms that biolubricant is a potential replacement of traditional cutting fluids because of its improved lubrication and cooling performance. High-viscosity biolubricant and nano-enhancers with high thermal conductivity are recommended for titanium alloy to solve the burn puzzle of the workpiece. Biolubricant with high viscosity and high fatty acid saturation characteristics should be used to overcome the bottleneck of wheel wear and nickel-based alloy surface burn. The nano-enhancers with high hardness and spherical characteristics are better choices. Furthermore, a different option is available for high-strength steel grinding, which needs low-viscosity biolubricant to address the debris breaking difficulty and wheel clogging. Finally, the current challenges and potential methods are proposed to promote the application of biolubricant.

The paper investigates the process of electroerosive diamond grinding by changing the polarity of electrodes in time in the cutting zone for processing various materials, and the distance between the grains is determined. The study aims to determine the effect on the distance between the grains of the electrical modes of electrical discharge grinding (ED grinding) and the characteristics of the wheel using the mathematical method of planning experiments. The planning of the experiment gave the result with the smallest error and made it possible to minimize the number of experiments. As a result of experimental studies, a mathematical model of the distance between grains has been constructed. This model considers the electrical process modes and the wheel characteristics. For various values of electrical modes and the wheel characteristics, using the functional dependence, it is possible to determine the distance between the grains. It was found that the most significant factors that affect the distance between grains are the frequency and relative pulse duration, grain size, and concentration of diamond wheels. The study results obtained allow using the functional dependence to calculate the grinding process's productivity, assess the cutting ability, and simulate the wear of the wheels without lengthy and expensive experimental studies.

“…However, the usage of cutting fluid causes several problems: the increase of manufacturing costs, the pollution of the environment and the harm to operators [6]. Extensive studies have been conducted to improve this situation, such as minimum quantity lubrication (MQL) [7,8], environmentally friendly cutting fluids [9,10], and dry cutting [5,11].…”

Dry milling of hardened steel is an economical and environmentally friendly machining process for manufacturing a mold and die. Advances in coating technology makes the dry milling a feasible approach instead of a traditional grinding process. However, the cutting condition is particularly severe in a dry machining process. High-performance coating is desired to meet the requirement of green and highly efficient manufacturing. This study concerned the performance of AlTiN-based coatings. The effect of Al content, and the AlTiN composite coating on the cutting performance of tools are investigated in terms of friction force at the tool–chip interface, specific cutting energy, cutting temperature on the machined surface, tool wear pattern and mechanism, and surface integrity. The results show that advanced AlTiN-based coatings reduce the force and cutting energy and protect the cutters from the high cutting temperature effectively. The main wear mechanisms of the coated tools are adhesive wear, chipping induced by fatigue fracture and abrasive wear. In general, the dry milling of hardened steel with AlTiN-based coatings gains a quite satisfactory surface quality. Furthermore, AlTiN-WC/C hard-soft multilayer coating performs well in reducing cutting force, preventing adhesion wear and isolating the cutting heat, being suitable for dry milling of hardened SKD11.
