Special Issue Information

Dear Colleagues,

A country’s economical growth and prosperity depends on the manufacturing industry and the production of high value-added products. Manufacturing companies are currently faced with challenges, such as the production of high-quality products, the need to lower production costs, the mass customization of products, shortening product life cycles, the environmental sustainability of future products, and unstable supply chains due to the emergence of various crises in the world, from the COVID-19 pandemic to wars in different regions. To respond to these challenges, engineers, professionals, and scientists have implemented new and advanced solutions in industrial processes such as sustainable green technologies, smart manufacturing and sensorics, robots, artificial intelligence/machine learning technologies, additive manufacturing/3D printing, Industry 4.0/5.0 principles, new and advanced materials, etc. To collect the latest research on the above-mentioned areas and beyond, the scope of this Special Issue includes (but is not limited to) scientific papers that deal with the following topics:

  • Advanced manufacturing technologies;
  • Non-conventional machining;
  • The machining of advanced materials;
  • The application of artificial intelligence/machine learning in advanced manufacturing/machining processes;
  • Smart manufacturing systems;
  • The application of robots and sensors in manufacturing/machining processes;
  • Additive manufacturing;
  • Industry 4.0/5.0 in advanced manufacturing;
  • The modeling and optimization of advanced manufacturing and machining processes.

A study of cryogenic drilling in sandwich composites was carried out. The materials used were carbon-fiber-reinforced polymer sandwich sheets with an inner foamed polyvinyl chloride core, composites with applications including protection structures of polar engineering equipment. The purpose of this study was to determine the feasibility of drilling at low temperatures using this composite by analyzing the thrust forces and the inlet and outlet diameters of the hole due to their influence on hole quality and their importance in a preassembly operation. Experimental tests were performed in laminates with thicknesses of 12 mm and 6 mm, drilling with liquid nitrogen (LN2) as a refrigerant to reach temperatures below −120 °C under cutting conditions of 2000–6000 rpm for drill bit rotation speeds and 200–600 mm/min for feed rates. Variables such as thrust forces and circularity error were measured, and a design of experiments, analysis of variance, and regression models allowed us to identify the influence of cutting conditions and foam thickness. Optimal cutting conditions were identified and contrasted: 2100–3100 rpm for drill bit rotation speeds and 200–320 mm/min for feed rates. The diameters achieved low deviations, H7 and H8 tolerances for inlet and outlet diameters, respectively, which allows for avoiding additional preassembly operations, which can be important during plate assembly using LN2 and in maintenance operations. Although good results have been obtained with other materials such as glass-fiber- and carbon-fiber-reinforced polymers, this sandwich material is lighter. Full article

The development of corrosion mechanisms is a major issue that industrial experts are faced with while dealing with all phases of metal exploitation. Damage caused by corrosion affects the increase in both direct and indirect costs of manufacture. With adequate surface protection technology, it is possible to lessen the intensity of corrosion mechanisms’ development. In order for the selected surface protection technology to provide its full protective action, it is necessary to be familiar with its process parameters. This paper deals with a surface protection system that creates a barrier between the aggressive environment and the base material. The tested barrier was created on a base material surface by electrostatic powder spraying. In this experiment, three types of base material (carbon steel, aluminum and galvanized steel) were coated by applying different combinations of operating parameters. Operating parameters, i.e., the voltage and strength of the electric current, were taken as numerical input variables in the experiment. Each experiment design was focused on measuring the thickness of the protective layer. Analysis of the obtained results and statistical data processing confirmed that appropriate parameters (input variables) provided the target thickness of the protective coating on each of the tested materials. Optimization of parameters contributes to the efficiency of production, shortens the processing time and ensures that coating thickness stays within the limits defined either by the manufacturer or the end user.
