Computer Aided 5-Axis Machining

CAD/CAM software provides the interface between the human user and the CNC machine. These machines are programmed with the required tool trajectory using a special command set called G-codes. These G-codes are a de facto standard in the CNC machine industry. G-code programs can be written manually for simple parts. However, in most case CAM software is used to produce G-code programs directly from CAD models. A CAM package typically produces a G-code program in two stages. First, tool paths consisting of generic cutter locations (CLDATA) are generated. The CLDATA consists of a list of tool positions in the workpiece coordinate system. The cutter locations must then be converted into G-code programs using a post-processor specific to the NC machines that will produce the part.
Introduction to Electric Motors
Published in Wei Tong, Mechanical Design and Manufacturing of Electric Motors, 2022
Mechatronics is the confluence of classical engineering disciplines such as mechanical engineering, electrical and electronic engineering, electromagnetism, sensor technology, drive and actuator technology, control theory, and computer science. In recent years, one of the design trends in the electric machine industry is to design intelligent mechatronics products. In fact, mechatronics is not only a modern design strategy but also a new way of doing business to gain a competitive advantage in the global market. As a result, it has been extensively used to design improved products and processes [1.143].
The change of the NVH characteristics of composite vehicle components as a result of visible and not visible damages
Published in Mohamad Al Ali, Peter Platko, Advances and Trends in Engineering Sciences and Technologies III, 2019
Composite materials, e.g. fiber reinforced polymers (FRP), are increasingly utilized in the vehicle and machine industry. FRP components can show damages that are not visible after an impact or a crash. A component that is damaged (even not visibly) loses its load capacity, its original energy absorption capacity and its NVH behavior can change significantly.

The machinery industry is the foundation of manufacturing industry development, and any manufacturing activity requires sophisticated machinery to complete. According to relevant data, Taiwan’s machinery industry holds a significant position in both domestic and foreign markets and has been the main driver of Taiwan’s remarkable economic growth in recent years. The machine tool is a machine for shaping metal or other rigid materials, usually by cutting, boring, grinding, shearing, and is known as ‘the mother of the machine’. It is used for machinery in the automobile, mould, and aviation industries, to name only a few. Machine tool product categories include integrated processing machines, lathes, drilling machines, milling machines, grinding machines and discharge machines. As ‘machinery is the mother of industry’, Taiwan’s machine tool industry is the driving force behind Taiwan’s remarkable economic growth and plays a very important role in economic development.
Robust and energy efficient trajectories for robots in a common workspace setting
Published in IISE Transactions, 2019
Nina Sundström, Oskar Wigström, Bengt Lennartson
The number of industrial robots deployed worldwide is estimated to be around 2 600 00 by the year 2019, an increase of about 1 000 000 units compared with the year 2015 (I.F. Robotics, 2014). This rapid growth is mainly due to the robotics industry that is being developed in China. Today, around 70% of industrial robots are used in the automotive, electrical/electronics, and metal and machinery industry. For example, in vehicle production plants, the car body construction facility alone often contains over 500 robots (Todtermuschke et al., 2014). Due to the increase in automation and restricted space, robots can often be placed such that the workspace of one robot overlaps with the workspace of neighboring robots. This overlapping space, referred to as the common workspace, is a critical region where collisions might occur.
