Explain how PLM is utilize in the design process. What is its consanguinity to CIC? Product Life Cycle Management (PLM) is an organizational model that involves all the beau mondes de vocalisationment, including the engineering design process, in the design and perform of a product. In addition to andiron software, specialised software products and technologies are utilise in conjunction.PLM is employ as a basis for creating the salt away corporate intellectual capital (CIC) of a company or organization. 5. summary the steps of problem identification in the id eation phase. enigma identification is an ideation process which consisting six elements Problem statement, Research, entropy gathering, Objectives, Limitations, and Scheduling. 6. What kinds of graphics are utilise in the ideation phase? The types of graphics used in ideation phase include charts, graphs, ideation sketches and drawings, design drawings, epitome and concept models, and demonstration graphics. 7.What is the designers notebook ready reckoner? How is it used? A designers notebook is exchangeable to a journal and contains many notes and sketches that are organized to show the passageway of development for a product and process. A well documented notebook contains notes, calculations, signatures, and dates. Keeping good note can impart an accurate document for an original design. 8. delimit the main activities in the refinement phase. Refinement is a repetitive (iterative or cyclical) process used to test a feeler design. Refinement consists of lead main area s modeling, design analysis, and design visualization. . find out the distinct kinds of models used in the design process. Modeling is the process of representing abstract ideas, words, and forms, by means of the orderly use of simplified text and images. Models are classified as either descriptive or predictive. Descriptive model presents abstract ideas, products, or processes in a recognize form. Descriptive models consisting trey-D frankfurter or physical collection plate models used simply to visually represent the design. prognosticative models can be mathematical or virtual three-D frankfurter models that can be used to analyze the motion or physical properties of the design. 0. soak up the distinct kinds of analysis techniques used in the design process. Types of analysis techniques used in the design process are Property analysis, appliance analysis, Functional analysis, benevolent factors analysis, Aesthetic analysis, Market analysis, and Financial analysis. 11. Outline the three ways the three-D model database can be used in the implementation phase. tether ways the 3-D model database can be used in the implementation phase are production, marketing and aid & documentation.Production is 3-D CAD models which are used to run machine tools and arrest parts and layout the grinder floor.

Product Data Management (PDM) is the name given to specific computer-based tools and used to track CAD or office documents with user-defined data fields, such as revisions, authors, date, and so aside in the development and manufacture of a product. inside PDM, Enterprise election planning (ERP) is a system that specifically focuses on the ordering of stuff and planning for the materials used for manufacture of a product. 14. What is the difference between conventions and standards?Conventions usually are accepted practices, rules, or methods. In good drawing, an example of a convention is the use of dashed lines or unfathomed features, on a multiview drawing to designate a feature inscrutable from the current viewpoint. Standards are sets of rules (formal ANSI or ISO) that govern how technical drawings are represented. 15. Describe ii remove engineering techniques. One of the reverse engineering techniques are the using of prepare measuring machine (CMM) that can measure objects accurately and then inputs the 3-D data into a CAD system and circumscribed it. other one is called examine by using laser or specialise photographic equipment to make cri tical measurement from existing parts. 16. Describe two unlike fast prototyping technologies. One of the rapid prototyping technologies are Stereolithography (SLA) which using a laser center beam to harden a light-sensitive polymer. Another one is fused Deposition Modeling (FDM) which using a liquid plastic to bushel a series of very thin layers to class and create a part. 17.Explain why an attempt might want to transshipment center data in an off-site data warehouse. Then reason of an enterprise want to retentivity data in an off-site data warehouse is protect against grow or other castasthophies at the companies engineering center. 18. Describe two different VR let on techniques. Two different VR display are the using of head-mounted display (HMD) that only for individual users and septuple projection systems called computer augementedd virtual environments (CAVEs) for multiple users in a larger physical space.Computer DrawingChapter 1 1. Explain the difference between e ngineers and technologists. Engineers are problem solvers. They are creative to use technical means to solve problems. They design products, systems, devices, and structures to improve our living conditions. They work with engineers and are concerned with the practical aspects of engineering in planning and production. 2. How can visualizing help an engineer in the design process? Visualization can help an engineer to mentally picture things that do not exist.Besides, engineers with good visualization ability are able to picture things in their minds. Furthermore, good visualization skills allow them to control mental image, allowing them to move around the image, change the form, look inside, and picture the inside of the mental image of the design problem. 3. What are the three main areas or phases of the model-centered design process? Do the activities in these areas happen in a sequential fashion? The three main areas of phases of the model-centered design process are ideation, refinement, and implementation.Windows 7 Check Your UnderstandingModel-centered engineering design is a nonlinear team approach to design that brings together the input, processes, and output elements necessary to produce a product. 4.
