“…Many efforts have been paid on this issue in recent years. 22–28 Aiming at maximum production rate, general milling operations and multi-pass milling operations were modeled to determine the optimal cutting parameters. 25,26 The optimal cutting parameters under various machining conditions were solved by geometric programming algorithm.…”

“…Several studies had been performed for the modeling of turning processes. 27,28 Compared to the traditional heuristic methods such as artificial neural networks, simulated annealing, and Lagrangian relaxation algorithms, a genetic algorithm is robust, global, and may be applied generally without recourse to domain-specific heuristics. Therefore, genetic algorithm usually is used to analyze the surface roughness data from a rough turning process or finish turning process.…”

Due to the high power consumption of machine tools in the manufacturing plants, study of the energy efficiency of machine tools has been the urgent need for sustainability. This article is focused on a comprehensive literature review about energy-efficient machine tools, including the analysis of energy loss, the modeling, and evaluating of energy efficiency of machine tools. These techniques are applicable for the design of new machine tools, and the analysis or redesign of the existing machine tools. Furthermore, some limitations and barriers of the previous studies on reducing machine tool energy consumption are discussed and outlined. The significant potential toward improving the energy efficiency of machine tools is presented, and some challenges are identified and summarized.

“…Aircraft engines, as the primary power source for airplanes, possess highly complex mechanical structures and manufacturing processes. Manufacturing quality of blades directly impacts their operational performance and service life [1]. Blade tip, located at the sharp end of blade, features a rounded fillet structure, which serves to control the development of horseshoe vortices, minimizes crack formation and blade corner failure during operation.…”

In order to achieve automatic rounding for blade tip, the study was conducted on small radius rounding based on elastic grinding, and a method of robot automatic grinding for small radius fillets of blade tip was proposed.The elastic grinding wheel with polyester ammonia fiber as substrate material is utilized the characteristics of elastic envelope deformation contact to grind sharp angles of blade tip to small radius fillets. Based on elastic contact theory and Preston equation, theoretical contact model and material removal model between grinding wheel and blade tip were established. Abaqus software was used to simulate and analyze the contact stress distribution and grinding removal amount. Simulation result demonstrates that the adaptive elastic contact deformation between grinding wheel and sharp angle of blade tip forms small surface envelope contact pattern and variable grinding removal amount, which can realize small radius fillet machining. Robot automatic rounding experiments for blade tip were conducted to verify feasibility and controllability of the machining method. The research results indicate that the elastic deformation of grinding wheel causes an arc-shaped contact stress distribution in the contact area of blade tip and abrasive coated on the substrate can achieve small radius fillet grinding. The combination of passive compliance formed by elastic grinding deformation and active force control is feasible to realize robot automatic rounding for small radius fillets, and the fillet radius can be controlled by changing grinding process parameters. Robot automatic rounding for blade tip is feasible, and machining process and accuracy are controllable and stable, which breaks through the traditional manual sandpaper grinding method and provides a new small radius fillet processing method.

The surface roughness is one of the most important characteristics of machined parts. A systematic method is proposed in the paper to simulate the shape generation processes in the boring operations and to estimate the surface roughness of the generated faces, based on the machining parameters. The simulation model includes both the models of the shape generation motions considering kinematic motion deviations and the cutting tool geometries. The shape generation motions with deviations are mathematically described by 4 by 4 transformation matrices. A set of points on the bored holes are generated through the simulations, and an assessment surface is obtained as the datum reference to estimate the 2-dimensional (2D) and the 3-dimensional (3D) surface roughness, based on the points generated by the boring process simulations. The proposed method provides us with a systematic method to estimate the surface roughness in the boring processes including the kinematic motion deviations.
