  • In the era of the fourth industrial revolution, the world is undergoing rapid social change. The purpose of this study is to predict the expected changes and necessary competencies and desired curriculum and teaching methods in the field of mechanical engineering in the near future. The research method was a Delphi study. It was conducted three times with 20 mechanical engineering experts. The results of the study are as follows: In the field of mechanical engineering, it will be increased the situational awareness by the use of measurement sensors, development of computer applications, flexibility and optimization by user's needs and mechanical equipment, and demand for robots equipped with AI. The mechanical engineer's career perspectives will be positive, but if it is stable, it will be a crisis. Therefore active response is needed. The competencies required in the field of mechanical engineering include collaborative skills, complex problem solving skills, self-directed learning skills, problem finding skills, creativity, communication skills, convergent thinking skills, and system engineering skills. The undergraduate curriculum to achieve above competencies includes four major dynamics, basic science, programming coding education, convergence education, data processing education, and cyber physical system education. Preferred mechanical engineering teaching methods include project-based learning, hands-on education, problem-based learning, team-based collaborative learning, experiment-based education, and software-assisted education. The mechanical engineering community and the government should be concerned about the education for mechanical engineers with the necessary competencies in the era of the 4th Industrial Revolution, which will make global competitiveness in the mechanical engineering fields.

  • The role of the Engineer in the era of nano-technology is explored, a trend in manufacture which is expected to yield a $20-30 billion per annum business throughout the world by the year 2020. The engineers who will be working in this subject will be required to have broadly based experience, over a range of traditional disciplines, such as physics. electronics, software engineering, control and mechanical engineering. As well as having an appreciation of other disciplines such as air conditioning, vibration analysis and its minimisation, the selection of materials for maximum stability and minimal thermal distortion as well as an understanding of ultra precision design and nano tribology. In other words the engineer who is to be successful in this new and emerging field, will have to be broader based than engineers of the past, where it was traditional to break up the elements of a discipline to smaller subsets. But as nano-technology advances and the subject brings about the evolution of nanotronics to provide a successful solution to emerging problems, it will be essential for a breed of engineers to develop who can consider the subject in a holistic manner. This paper therefore considers the emergence of nano-technology, predicts the subsets of the development and places them in context of the new engineer which will be required in increasing numbers. The paper summarises the skills of the proposed nanotronics engineer and provides a basis for their training and development.

  • Topology optimization is widely accepted as a conceptual design tool for the product design. Since the resulted layout of the topology optimization is a kind of digital images represented by the density distribution, the seamless process is required to transform digital images to the CAD model for the practical use. In this paper, the general process to construct a CAD model is developed to apply for topology images based on elements. The node density and the morphology technique are adopted to extract boundary contour of the shape and remove the noise of images through erosion and dilation operation. The proposed method automatically generates point data sets of the geometric model. The process is integrated with Pro/Engineer, so that the engineer in practice can directly handle with curves or surfaces form digital images.

  • A automatic production system was developed for high productivity and safety. The semi-progressive die was unfavorable for more productivity, safety, material extravagance and incongruent high-speed production. Developed progressive die is suitable for the high production and guarantee triple production by acceptance of three array type for automobile adjust plate. We adopt Pro-$Engineer{\circledr}$ for three dimensional computer aided design suitable for the disassembly and assembly evaluation. The conclusion of this study is as follow. First, press die parts solid modeling system is built by using Pro-$Engineer{\circledr}$ through this research and verified allowable tolerance and possibility of assembly and disassembly of parts. Therefore we can reduce die manufacturing time and cost. Second, We produce 1000 units pet hot coil 1ton by traditional method, but we can acomplish material saving effect about 12% as 120 units in case of new progressive die. Fourth, we acomplished manufacturing cost curtailment effect more than 20% in comparison with traditional method.

  • This paper examines the emergence of mechanical engineers in the technological and social context of professionalization in England. Despite their technological progress, most steam engine wrights and machine tool builders were individual workshop owners working to order in the early 19th century. In the 1830s and 1840s, however, the railway boom produced so called railway engineers by providing them with some managerial experience as the canal building did in civil engineering. Railway engineers played a dominant role to establish the Institute of Mechanical Engineers(IME) in 1848. It was IME that stated what is a mechanical engineer and helped its members be in the similitude of the civil engineers in social and technological activities.
