Mechanical Engineering: Design and Manufacturing

A topological model of limitations in design for manufacturing

Research in Engineering Design. Design for manufacturing DFM is a methodology that requires the use of specific manufacturing information at all stages of design. The method relies on a collection of informal and often controversial principles that seem to have eluded the benefits of formal analysis. We study the properties of the transition map in the presence of design and manufacturing variations, and show that its continuity is closely related to the structure of design and manufacturing topological spaces. The main result of this paper establishes conditions on these spaces under which design for manufacturing cannot be described by any continuous transition map. In practical terms, our study reveals the limitations of many DFM systems and approaches in their ability to relate design and manufacturing knowledge, and explains these limitations in terms of a basic incompatibility between the underlying design and manufacturing representations. We discuss how our model applies to DFM relative to traditional manufacturing methods such as casting and stamping and we speculate what changes might occur for alternative manufacturing technologies such as electrical discharge machining EDM , stereolithography, laser machining, and particle deposition.

Mechanical engineering is the discipline that applies engineering physics , engineering mathematics , and materials science principles to design , analyze, manufacture, and maintain mechanical systems. It is one of the oldest and broadest of the engineering disciplines. The mechanical engineering field requires an understanding of core areas including mechanics , dynamics , thermodynamics , materials science , structural analysis , and electricity. In addition to these core principles, mechanical engineers use tools such as computer-aided design CAD , computer-aided manufacturing CAM , and product life cycle management to design and analyze manufacturing plants , industrial equipment and machinery , heating and cooling systems , transport systems, aircraft , watercraft , robotics , medical devices , weapons , and others. It is the branch of engineering that involves the design, production, and operation of machinery. Mechanical engineering emerged as a field during the Industrial Revolution in Europe in the 18th century; however, its development can be traced back several thousand years around the world.

Description:

Excellent design and effective manufacture are the pre-requisites of a successive industry. There is a general impression that the quality of Indian products can still be improved. The fact that consumers have lost their confidence on Indian-made products cannot be denied. This problem can be solved only by designing and manufacturing better products through improved methodology. Keeping this in view, the subject Design and manufacturing purpose to present the methods and procedures of design and manufacture. Although engineers are not the only people who design things, the professional practice of engineering is largely concerned with design.
