【正文】 wing aids. Creation and maintenance of design databases (libraries of designs) permits storing designs and symbols for easy recall and application to the solution of new problems. 4. Quick and convenient design analysis the designer can evaluate alternative design thereby considering more possibility while speeding up the process at the same time. 5. Simulation and testing of designs. Some puter systems make possible the simulation of a product39。s productivity. Computeraided design drafting (CADD), an offshoot of CAD, is the process of Generating engineering drawings and other technical documents by puter and is more directly related to drafting than is CAD. The CADD user inputs data by keyboard and/or mouse to produce illustrations on the monitor screen that can be reproduced as paper copies with a plotter or printer. Engineers generally agree that the puter does not change the nature of the design process but is a significant tool that improves efficiency and productivity. The designer and the CAD system may be described as a design team: the designer provides knowledge, creativity, and control。 (d) inadequate, and unverified, quality control procedures。 (b) fail are to fore, and take into account the reasonable uses for the product( where possible, the designer is further advised to foresee and account for misuse of the product, as there have been many product liability cases in recent years where the claimant, injured during misuse of the product, has sued the manufacturer and won)。 (b) functional。 本科畢業(yè)設(shè)計(論文) 外文資料翻譯 Material Selection During recant years the selection of engineering materials has assumed great importance. Moreover, the process should be one of continual reevaluation. New materials often bee available and there may be a decreasing availability of others. Concerns regarding environmental pollution, recycling and worker health and safety often impose new constraints. The desire for weight reduction or energy savings may dictate the use of different materials. Pressures from domestic and foreign petition, increased serviceability requirements, and customer feedback may all promote materials reevaluation. The extent of product liability actions, often the result of improper material use, has had a marked impact。 in addition, the interdependence between materials and their processing has bee better recognized. The development of new processes often forces reevaluation of the materials being processed. Therefore, it is imperative that design and manufacturing engineers exercise c
