“…Such approaches apart from being inefficient, did not take account of multiple factors affecting machine performance. Other researchers have used mathematical models based on the theory of cutting mechanics and blade geometry [15], [16]. Though the models are useful in evaluating the effects of various design parameters on the objectives, they involve great analytical rigor and complex functions that do not guarantee optimality.…”

The focus of current research on plastic grinding machines has been improvement of efficiency. Parameters such as number of rotor blades, number of fixed blades, blade geometry, clearance between fixed and rotor blades, machine power input and throughput have been studied in previous research. The problem is that little research effort has been focused on optimization of many of such parameters combined. This research aims to improve throughput of plastic grinding machine by mathematical optimization of the five parameters to achieve higher throughput. In this paper, we optimized the parameters using generalized reduced gradient nonlinear programming. We also carried out correlation of the parameters using Pearson correlation coefficients. There was a strong correlation between maximum machine throughput and all the studied parameters. We found that throughput was optimal with nine rotor blades, two fixed blades, blade angle of 500, clearance of one millimetre, and power input of at least 5 Hp.

“…With the rapid development of China's aviation industry, the demand for high-quality and large-scale monolithic components has increased sharply. The material of the main force-bearing components of aircraft have been using aluminum alloy for a long time [1,2] , among which 7055 aluminum alloy proposing high strength, high fracture toughness, and excellent resistance to fatigue crack expansion are widely used as monolithic components in the manufacture of aircraft skins, spars, bulkheads, gangways, landing gears, etc. [3,4,5] .…”

The residual stress induced by the process of high-speed milling is an essential factor affecting the machining deformation of structural materials. The two-dimensional modeling and numerical simulation of high-speed milling of 7055 aluminum alloy were carried out to investigate the influence of key milling process parameters on the surface residual stress of aluminum alloy, using finite element approach. Through single factor simulation experiment and multi-factor orthogonal simulation experiment, the effects of milling speed, feed rate, milling depth, milling width, rake angle and relief angle on the surface residual stress of aluminum alloy were discussed. The optimized parameter scheme was obtained by range analysis method. The results demonstrate that the surface residual stress of 7055 aluminum alloy increases with the increase of milling speed, feed per tooth and milling depth, and decreases with the increase of milling width; Using the optimized milling scheme (milling speed 2000 m / min, feed per tooth 0.1 mm / z, tool relief angle 4 °, tool rake angle 16 °, milling depth 10 mm, milling width 10 mm) could reduce the surface tensile residual stress; while using the optimized scheme (milling depth 10 mm, tool rake angle 16 °, milling width 4 mm, feed per tooth 0.5 mm / z, milling speed 4000 m / min) could reduce the surface compressive residual stress.

Although the manufacturing industry has improved the quality of processing, optimization and upgrading must be performed to meet the requirements of global sustainable development. Sustainable production is considered to be a favorable strategy for achieving machining upgrades characterized by high quality, high efficiency, energy savings, and emission reduction. Sustainable production has aroused widespread interest, but only a few scholars have studied the sustainability of machining from multiple dimensions. The sustainability of machining must be investigated multidimensionally and accurately. Thus, this study explores the sustainability of machining from the aspects of equipment, process, and strategy. In particular, the equipment, process, and strategy of sustainable machining are systematically analyzed and integrated into a research framework. Then, this study analyzes sustainable machining-oriented machining equipment from the aspects of machine tools, cutting tools, and materials such as cutting fluid. Machining processes are explored as important links of sustainable machining from the aspects of dry cutting, microlubrication, microcutting, low-temperature cutting, and multidirectional cutting. The strategies for sustainable machining are also analyzed from the aspects of energy-saving control, machining simulation, and process optimization of machine tools. Finally, opportunities and challenges, including policies and regulations toward sustainable machining, are discussed. This study is expected to offer prospects for sustainable machining development and strategies for implementing sustainable machining.
