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 The quality of robotic laser welded parts is related to the joint location, the trajectory of the laser focal point and the process parameters. By performing in-process monitoring, it is possible to acquire sufficient process knowledge for post-inspection to evaluate the geometrical weld quality. The existing solutions for such systems operate along linear welds. This paper contributes with a quality inspection system for robot laser welding, that can handle double-curved geometries. Th...

Abstract Vibration problems occur in automation and robotics systems frequently. Automation systems often have components that rotate at high speeds. When rotating equipment is unbalanced, it could cause a lot of vibration. This type of forced vibration not only will create mechanical noise, it could cause accuracy issues and affect production yield in precision equipment. Even if the source of the vibration can be identified, sometimes it is difficult to fix the issue due to cost or schedule co...

Abstract Many manufacturing environments have implemented methods of collecting data from their processes relating to vibration, temperature, or sound. With the data stored, manufacturers can run analytics to plan maintenance schedules and track machine health. However, in many cases, these maintenance schedules and health tracking are largely reactionary, largely implemented through experience rather than through predicting the onset of critical events and taking measures to prevent them. This ...

Abstract Appropriate lighting is one of the indispensable elements in inspection using machine vision system. Illumination variation affects the accuracy and robustness of an inspection method that employs a machine vision system. The lighting inhomogeneity is the disturbing signal that needed to be suppressed to achieve accuracy and consistency in surface roughness quantification. In this work, the illumination compensation techniques are used for ground surface roughness evaluation by statisti...

Abstract Today’s most advanced Industrial systems are built on a very solid information technology basis. To serve and to operate the extremely complex supply chain, the industry needs modern, interconnected infrastructure, where sensors, industrial and office devices are connected. Therefore, real-time demands could take immediate action in every step of the supply chain elements. The more complex the information infrastructure is, the more risk emerges in the field of cybersecurity. Cybersecur...

Abstract Actually, in many industrial applications, like automotive industry, mass decreases and fuel economy constitute very important features. Light alloys are extensively used in automotive applications and simultaneously, the constant industrial progress forces low-cost innovative machining routes to be used after the manufacturing process oriented to transform the product into a right shape with high accuracy of the geometry and good surface quality. In this paper, a general overview of th...
Abstract This research aims at finding some alternative solutions to the conventional reinforcement of the masonry in areas with low seismic levels, namely the confination with concrete piles and belts, as provided in the Romanian norms in force, replacing the concrete columns with vertical voids in AAC masonry with metal fibre disperse reinforced concrete.For the masonry modules that were initially tested experimentally, numerical tests were performed using the finite element method with the Ab...
