Tài liệu Process Selection From Design to Manufacture P1 ppt

[...]... assembly processes The intention is to promote the generation of design ideas and facilitate the matching and tuning of a design to a process, and The provision of methods and data to enable the exploration of design solutions for component manufacturing and assembly costs in the early stages of the design and development process To provide for the first point, a set of so-called manufacturing PRocess. .. of common manufacturing processes and material groups is included to illustrate the design costing process and quantify the effect of design choices and alternative process routes on manufacturing cost The work is presented in three main parts Part I addresses the background to the problem and puts process selection and costing into the context of modern product introduction processes and the application... product in the market place As mentioned previously, in selecting processes and tuning designs for processing many factors need to be taken into consideration The manufacturing PRIMAs presented in this part of the book attempt to provide the knowledge and data required to underpin this decision making process provided by the various process selection strategies However, it is the PRIMAs that provide the... Techniques in design for manufacture and assembly 7 Fig 1.7 Pump assembly and test machine overall assembly results Fig 1.8 Results from 60 product studies Similar savings have been reported by others involved with the application of techniques in design for manufacture and assembly (1.34) It is also worth commenting that the designs coming out of the process tend to be more reliable and easier to manufacture. .. Computer-aided Design Design for Assembly Design for Manufacture Design of Experiments Failure Mode and Effects Analysis Product Design Specification Product Introduction Management Process Information Map Quality Function Deployment Acronyms – manufacturing processes AJM ATB ATS CM CNC CW DB DS DFW DFB EBM EBW ECG ECM EDG Abrasive Jet Machining Automated Torch Brazing Automated Torch Soldering Chemical Machining... opportunity to exploit any benefits from alternative processes may be lost The greatest opportunity in design for manufacture occurs at the initial design stage, for while there are also possibilities for a product in production to be modified, there are many additional constraints This is also illustrated in Figure 1.1 On top of the problems of tooling and equipment, it is not uncommon to find that... detailed assessments regarding the technological and economic feasibility of a process Design considerations are provided to enable the designer to understand more about the technical feasibility of the design decisions made The process quality considerations give valuable information on process conformance, including data on process tolerance capability associated with characteristic dimensions A good proportion... The selection of an appropriate set of processes for a product is very difficult to perform effectively without a sound Product Design Specification (PDS) A well-constructed PDS lists all the needs of the customers, end users and the business to be satisfied It should be written and used by the Product Team and provide a reference point for any emerging design or prototype Any conflict between customer... customer needs and product functionality should be referred back to the PDS The first step in the process is to analyze the design or prototype with the aim of simplifying the product structure and optimizing part-count As shown earlier, without proper analysis design solutions invariably tend to have too many parts Therefore, it is important to identify components that are candidates for elimination or... manufacturing technology selected Estimation of component manufacture and assembly costs during the design process is important for both assessing a design against target costs and in trade-off analysis Overall, the left-hand side of Figure 1.18 is closely related to DFA, while the right-hand side is essentially material /process selection and component design for processing, or consideration in DFM A reader interested . 7:42PM //SYS21///INTEGRAS/B&H/PRS/FINALS_07-05-03/0750654376-CH000-PRELIMS.3D – 3 – [1–16/16] 13.5.2003 7:42PM Process Selection From design to manufacture Second edition K.
