Special Issue Information

Dear Colleagues,

Advanced materials such as aerospace composites, advanced ceramics, glass, metallic alloys and others are broadly used in various high-tech industries including aerospace, automotive, defense, military, electronic, medical, marine and several others. High-tech industries demand excellent surface quality, high precision, and no microstructural damage to machined components owing to their classified applications. Various advanced materials have been considered difficult-to-machine materials due to their heterogeneous and special material properties and structures. Conventional machining technologies do not meet the requirements for machined components for their specific applications. Therefore, non-conventional machining technologies are preferred to overcome the challenges of conventional machining technologies, but their commercial usage is still very limited due to complexity of the advanced machining systems, specialized tools designs, advanced material properties and structural variations and high skills and expertise needed, as well as the limited availability of machine tools. Therefore, there is a special need to support the high-tech industries with state-of-the-art research and innovations to tackle the challenges in the flexible design and implementation of nonconventional machining for several advanced material processing.

This Special Issue will be devoted to state-of-the-art research on the various aspects of nonconventional machining technologies for advanced material applications such as optimum designs of non-conventional machining systems, specialized cutting tool designs, integration of machining systems, non-conventional machine tool precision measurements and calibrations, cutting tool wear, machining efficiency improvements, machining cost reductions, non-conventional machining simulation model development, and development of automatic non-conventional machining systems, etc.

We seek submissions with original perspectives and advanced thinking on the theme addressed. Original research on theories, simulations, designs, experiments, and technical issues of nonconventional machining technologies for advanced materials applications is welcome.

Possible topics include but are not limited to the following:

  • Machining properties of advanced materials (aerospace composites, advanced ceramics, glass, metallic alloys and others);
  • FE Cutting simulations of advanced materials;
  • Design of specialized cutting tools of non-conventional machining processes;
  • Design and development of various non-conventional machining technologies;
  • Cutting tool wear;
  • Precision and calibrations of machine tools;
  • Machining efficiency improvements;
  • Flexible non-conventional machining technologies;
  • Machining mechanisms;
  • Surface morphological characteristics.

Abrasive disc grinding is currently a key manufacturing process to achieve better accuracy and high-quality surfaces of TC17 components. Grinding force, which results from the friction and elastic–plastic deformation during the contact and interaction between the abrasive grains and the workpiece, is a critical parameter that represents the grinding accuracy and efficiency. In order to understand the influence factors of grinding force, the characteristics of the flexible abrasive disc grinding process were studied. Considering the contact state between the abrasive tool and the workpiece, the theoretical model of normal grinding force was established in detail, from macro- and micro-perspectives. By conducting single-factor and orthogonal grinding experiments of TC17 components, the influence of different process parameters on the normal grinding force was revealed. The normal grinding force prediction models of the abrasive disc grinding process were developed based on the Box–Behnken design (BBD) and particle swarm optimization–back propagation (PSO-BP) neural networks, respectively. The results showed that the normal grinding force was negatively correlated with the disc rotational speed, and positively correlated with the contact angle, grinding depth, and feed rate, and the interaction of the factor feed rate and grinding depth was the more influential factor. Both the BBD and PSO-BP force models had good reliability and accuracy, and the mean absolute error (MAE) and mean relative error (MRE) of the above two prediction models were 0.22 N and 0.16 N, and 13.3% and 10.9%, respectively.

Silicon carbide particle-reinforced aluminum matrix composites (SiCp/Al) find diverse applications in engineering. Nevertheless, SiCp/Al exhibit limited machinability due to their special structure. A pulsed laser ultrasonic vibration assisted cutting (PLUVAC) method was proposed to enhance the machining characteristics of SiCp/Al and decrease surface defects. The finite element model was constructed, considering both the thermal effect of the pulsed laser and the location distribution of SiC particles. The model has been developed to analyze the damage forms of SiC particles and the formation mechanisms for the surface morphology. The influence of pulsed laser power on average cutting forces has also been analyzed. Research results indicate that PLUVAC accelerates the transition from the brittleness to the plastic of SiC particles, which helps to reduce surface scratching caused by fragmented SiC particles. Furthermore, the enhancement of surface quality is attributed to the decrease in surface cracks and the beneficial coating effect of the Al matrix. The accuracy of the simulation is verified by experiments, and the feasibility of PLUVAC method to enhance the surface quality of SiCp/Al is confirmed. Full article
