In mass customization, specialized CAD programs can quickly adapt sizes in two ways: firstly, by adjusting existing patterns based on one individual’s body measurements and/or fit preference and, secondly, by creating made-to-measure patterns directly from an individual’s body measurements, with no pre-existing pattern. 5Ĭonnection to computerized cutting systems.ĬAD databases streamlined the mass production product development process by storing old patterns for adjustment and reuse. Grading functions to create pattern blocks in multiple sizes from the sample size blocks. Modular piece access and storage for mass production and customization applications. 2Ĭreation of individual and size specifications for ready-to-wear clothing. 1ĭatabase management of patterns for access, manipulation and storage. CAD legacy systems have since been upgraded to provide multidepartment integration and access and to serve a multiplicity of functions including the following. Most clothing businesses initially adopted CAD to organize and store patterns and to use and adapt them to create new styles over time. The production CAD system is then used for producing of the detail drawings, typically based on DXF files transferred from AutoCAD.ĬAD pattern-making technology was developed as a stand-alone process. One mode of using Design ++ is to use AutoCAD™ as a visualization tool (e.g., for schematics and 3-D layouts) regardless of what system is used for an organization's production CAD system. Once the graphics are “inside the CAD system,” the regular CAD functions such as changing point of view, altering layer colors, removing hidden lines, doing shading, etc. Other tightly and loosely coupled connections are planned. Currently such connections are available for Computervision and Calma. “Loosely coupled” means that the communication is one way, from Design ++ to the CAD system. Thus, not only are the graphics generated by the symbolic model within Design ++, but location information about an object moved on the CAD canvas may be transmitted back to Design ++ and the underlying symbolic model updated.

A “tightly coupled” system (currently AutoCAD) maintains a two-way link. Computer-Aided Design SystemsĬAD systems are either tightly or loosely coupled to Design ++. Levitt, in Artificial Intelligence in Engineering Design, Vol5.4.4. Some products still benefit from more traditional methods of production, such as those with a reputation or tradition for being hand made.David J. These methods have been used for a long period of time, however are less efficient, more expensive and more time consuming than new methods of CAD and CAM.

Traditional methods of production involve drawing designs by hand, creating a number of prototypes and using humans to manually produce goods or operate machinery. How these differ from traditional methods of production Good for producing on a mass/flow production line Machines can run constantly on repetitive tasks By using CAM, designs can be sent to CAM machines such as laser cutters, 3D printers and milling machines. It becomes easier to design and test a range of ideasĬomputer aided manufacture (CAM) involves using computers to control machines to undertake the production of goods. Some testing and consumer feedback can be done before costly production takes placeĭifficult to keep up with constantly changing and improving technology Advantages of CADĭesigns can be viewed from all angles and with a range of materials Once production is finalised, these designs are sent to computer aided manufacture (CAM) machines to be formed. This enables businesses to visualise new designs in a variety of materials and send images around the world for collaboration and consultation.
