  2. Arbor milling - Wikipedia

    en.wikipedia.org/wiki/Arbor_milling

    Arbor milling. Arbor milling is a cutting process which removes material via a multi-toothed cutter. An arbor mill is a type of milling machine characterized by its ability to rapidly remove material from a variety of materials. This milling process is not only rapid but also versatile.

  3. Structured analysis - Wikipedia

    en.wikipedia.org/wiki/Structured_analysis

    Structured analysis consists of interpreting the system concept (or real world situations) into data and control terminology represented by data flow diagrams. The flow of data and control from bubble to the data store to bubble can be difficult to track and the number of bubbles can increase. One approach is to first define events from the ...

    SADT basis element. Structured analysis and design technique (SADT) is a systems engineering and software engineering methodology for describing systems as a hierarchy of functions. SADT is a structured analysis modelling language, which uses two types of diagrams: activity models and data models. It was developed in the late 1960s by Douglas T ...

  5. Bottom–up and top–down design - Wikipedia

    en.wikipedia.org/wiki/Bottom–up_and_top–down...

    A top–down approach often uses the traditional workshop or microfabrication methods where externally controlled tools are used to cut, mill, and shape materials into the desired shape and order. Micropatterning techniques, such as photolithography and inkjet printing belong to this category. Vapor treatment can be regarded as a new top–down ...

  6. Problem frames approach - Wikipedia

    en.wikipedia.org/wiki/Problem_Frames_Approach

    Problem analysis or the problem frames approach is an approach — a set of concepts — to be used when gathering requirements and creating specifications for computer software. Its basic philosophy is strikingly different from other software requirements methods in insisting that: The best way to approach requirements analysis is through a ...

  7. Milling (machining) - Wikipedia

    en.wikipedia.org/wiki/Milling_(machining)

    Milling is the process of machining using rotary cutters to remove material [ 1 ] by advancing a cutter into a workpiece. This may be done by varying directions [ 2 ] on one or several axes, cutter head speed, and pressure. [ 3 ] Milling covers a wide variety of different operations and machines, on scales from small individual parts to large ...

  8. 4+1 architectural view model - Wikipedia

    en.wikipedia.org/wiki/4+1_architectural_view_model

    The four views of the model are logical, development, process and physical view. In addition, selected use cases or scenarios are used to illustrate the architecture serving as the 'plus one' view. Hence, the model contains 4+1 views: [1] Logical view: The logical view is concerned with the functionality that the system provides to end-users ...

  9. Systems development life cycle - Wikipedia

    en.wikipedia.org/wiki/Systems_development_life_cycle

    A systems development life cycle is composed of distinct work phases that are used by systems engineers and systems developers to deliver information systems.Like anything that is manufactured on an assembly line, an SDLC aims to produce high-quality systems that meet or exceed expectations, based on requirements, by delivering systems within scheduled time frames and cost estimates.
