Cutting Processes

Nowadays parts made of up-to-date engineering plastics are used more and morein mechanical engineering practice. These machine-elements are produced most frequentlyby injection molding or by one cutting process. The injection molding technology are usedgenerally for great number of pieces, in case of serial production while cutting processes arepreferred to piece (unit) or smaller number production.We used lathe and measured the main- and feeding-directional cutting force at differentengineering polymers (cast PA6, POM C and UHMW PE HD 1000). The analysis made canbe well used in practice.

Logistics Quality

Abstract This paper demonstrates the advantages of logistics studies which include detailed transportation simulations based on mechanical engineering principles. Complex transportation system parameters are often averaged, aggregated, or assumed, resulting in models with questionable validity. Detailed simulations of route-specific real-world vehicle performance for analysis systems (such as Transport Probability Analysis) can often provide more accurate predictors of logistics system performance, resulting in valid projections of system transport times, costs, inventory levels, energy usage, standards, and quality control measures. A discussion of logistics is followed by examples of progressively complex logistics transportation simulations and models. Results of a moderately detailed performance-based simulation of high speed trains for the Texas Triangle are used to demonstrate the fallacy of assuming “average” performance measures. Future logistics studies will require detailed vehicle performance simulations using sound mechanical engineering practice, requiring interdisciplinary teams which include mechanical engineers.

The German guideline “Fracture Mechanics Proof of Strength for Engineering Components” has been released in 2001 as a result of activities sponsored by the Research Committee on Mechanical Engineering (FKM), task group “Component Strength”. The guideline compiles basics for the integrity assessment of cracked components subjected to static or cyclic loading and provides a step-by-step computational procedure for the use in engineering practice. The paper gives an overview of the guideline, describes its specific features, contents and some new topics included in the last 3rd edition (2006).

Industrial Needs

According to the Canadian Engineering Accreditation Board, all engineering programs in Canada must include a minimum of 15% of activities allocated to design. One can assume that these activities vary in content and scope between different programs. In this context, how can we define engineering design? Is there a recognized academic definition? Should our design goals be aligned with industrial needs and practice and if so, what should be the content of our design activities and how should they be structured? How is it possible to reach academic design goals given the limited resources available in our engineering schools? These are some of questions that will be addressed in this paper with the intent of better understanding the very important aspect of design’s engineering practice. Additional topics include: the change in design philosophy and approach resulting from a major program reform in the Mechanical Engineering Department at Université de Sherbrooke as well as the importance of industrial partnerships in design projects.

Continuous revision of curriculum is important in academic institutions. First revision of the curriculum of Mechanical Engineering was completed in 1999. Second revision of the curriculum was started in 2009 and completed in 2015. It is important for engineering practice to make competitive curriculum for producing quality students by using modern techniques, skills and engineering tools. Analysis of Curriculum-1999 and 2009 were performed. General out lines of the curriculum revisions were introduced. Features of the curriculum revisions were discussed in detail. Competitive analysis of curriculums of contemporize universities of Asia were performed. Accreditation process were analysed, taking reference of European and American systems. Updating equipment in workshop and laboratories with latest technologies were found necessary.

Industry Needs

In a research cycle, researchers need to publish their work and readers expect reliable arguments and information. Seeing society and industry needs relate to mechanical engineering for now and in the future, Mechanical Engineering for Society and Industry (MESI) is an important journal to discuss problems and solutions in mechanical engineering practice. The articles in this journal are a representation of scientific editors and advisory boards' dedication, reviewers' contributions in improving articles quality, and authors contributions in providing standardized articles. Hopefully, this journal can be a source of new insights and inspiration for further research, as well as a new reference for society and industry to solve their problems.

Design Experience

Design activity is core to modern engineering practice. Some design experience is demanded by professional bodies that accredit degree engineering programmes (e.g. ABET and ECSA). The purpose of this paper is to track design related topics through the curriculum of the mechanical engineering degree programme at the University of Botswana. A questionnaire was designed and administered to staff teaching on the programme. The responses were used to map design components in the curriculum and assess the design experience of students. The results showed that design topics were delivered in various courses and the knowledge gained by students increased steadily from Year 3 to Year 5. Some observed deficiencies in the teaching of design included lack of industry recommended projects, negligible application of design software, and the use of only single discipline based problems (i.e. no multi disciplinary teaching approach). It was concluded that a programme review is needed to improve the pedagogy of design and enhance programme robustness. It is envisaged that the study will help in designing a new mechanical engineering curriculum to satisfy accreditation requirements.

Machine Elements

The Design of Machine Elements course is one of the most difficult and complicated courses in the Mechanical Engineering program. It requires inventive concept generation, the knowledge of geometrical design, and basic knowledge of stress and deformation analyses. On those three elements, the machine elements design philosophy is established and further developed. The course material has to be chosen carefully since the time constrains will allow to cover design of only few essential machine elements. The material is covered by lectures, textbook readings, homework problems, and design projects. In addition to the textbook content the course contains five special elements: Idea Generation, Safety Considerations, Design of the Day (DoD), a Designer’s Liability study, and three projects including Final Project – Shaft Design. In the Idea Generation project, students generate an idea of machine or mechanical device. The Safety Consideration project is done by inspection and documentation of unsafe elements on campus. The Shaft Design Project had students design a shaft system under given constrains. In DoD students present existing advanced machines chosen using different sources or their own industrial internship experience. The Liability assignment addresses the designer’s legal responsibility in case of a defective product that caused an injury or accident. The material taught in the course is larger than conventional machine element design course. The elements added that are beyond the structural analysis bring better understanding of engineering problems during the Senior Design course and later during engineering practice. They allow the students to connect the theory with the real world of engineering challenges. This gives students more satisfaction during the learning process and cognitive benefits during engineering practice. The unconventional inventive design approach of the teaching team (course instructor and GTA) to problem solving is based on many years of instructor’s experience in teaching of engineering problem solving and design. The learning pattern in which students work in teams, both in problem solving and in design exercises, also helps to conduct the course. Thanks to all these elements the learning experience of the course is unique and engaging despite the high level of difficulty associated with it.
