The growth of Digital Dentistry has opened new potentials in the dental restoration sector where personalised restorations could be made in a much shorter time than before. Zirconia has been widely used due to its excellent wear properties and bio-compatibility. Zirconia is machined primarily in its pre-sintered state, using carbide tools. Even in its pre-sintered state, zirconia is abrasive and caused tool wear. Tool wear is affected by tool substrate used, cutting conditions used, machining me...

Dies and moulds are fundamental elements in the manufacturing of a wide variety of products. The surface polishing of dies and moulds with complex features largely relies upon time-consuming manual work of skilled workers and, as a result of the diminishing availability of skilled people, has become the most costly step in the manufacturing system. Robot-assisted polishing (RAP) technology has been investigated as an alternative or supplement to the conventional manual polishing process in the m...

Abstract Polycarbonates are naturally transparent amorphous polymers, used extensively nowadays to replace some of the applications of glass. Polycarbonates possess excellent impact and heat resistance, which made them suitable candidates for automotive, semiconductor, medical, household, and many industrial applications. Although polycarbonates are mostly formed by molding, further processing, especially machining of them still remains challenging. The objective of this study is to focus on an ...

Abstract The economy of using agro-wastes in the design of novel ceramic materials is a good option to environmental waste management. A good number of these agro-wastes have been adjudged to be rich in silica, thus making them potentially useful materials for the development of silica-based refractory compounds. The present study was motivated by this prospect and the investigation focused on the structural characteristics of silica-based carbothermal derivatives of rice husk (ash). Rice husk a...

Abstract Increasing demands in machining of high-tech materials and dry machining lead to higher thermal and mechanical loads on cutting tools. In response to these challenges, enhanced coating solutions are applied to increase performance and life of cutting tools. However, during the production process the cemented carbide substrates are contaminated with grinding oils and residues of organic material. For the subsequent physical vapor deposition (PVD) coating process an intensive and high-qua...

Abstract Manufacturing companies are experiencing the fourth industrial revolution characterised by the introduction of new technologies into production equipment, such as the Cyber Physical Systems and the Digital Twin simulations. Companies are then challenged by the digitization of products and production systems information, which leads to new potentials for digital continuity – i.e. information available and continuously updated for the decision makers – along the lifecycles. A semantic dat...

Abstract Bulk metallic glass (BMG) is a new class of material discovered in recent years with prospective applications in space, nuclear reactor engineering, biomedical, and electronics industries. Metallic glasses are difficult to be machined using conventional machining processes due to the extreme hardness and non-crystalline/amorphous structure of metallic glass. Therefore, this study aims to investigate the machinability of metallic glass using a non-contact based process, called micro elec...
