Flexible Manufactoring Cells ( FMC)

Manufactoring cells can be made flexible by using machining centers, CNC machines, and industrial robots or other mechanized systems for handling materials and work in progress. Flexible manufactoring cells also can be designed and operatedwith a central robot. Cell design and operation are more exacting, as the machines, the robots, the end effectors, and the control systems must function properly.

Design for Disassembly (DFD)

The manner and ease with which a product may be taken apart for maintenance or replacement of its parts is another important consideration in product design. Consideri for example, the diffulties one has in removing certain components from under the hood of some automobiles. Similar diffulties exist in the disassembly of several other products. The general approach to design for disassembly requires the consideration of factors that are similar to those outlined for assembly. Analysis of computer of physical models of products and their components with regard to disassembly generally indicate any potential problems, such as obstructions, size of passageways, lack of line sight and the difficulty of firmly gripping and guiding objects.

Material Handling

Material handling is defined as the functions and systems associated with the transportation, storage, and control of materials and parts in the total manufactoring cycle of a product. The total time required for actual manufactoring depends on part size and shape and set of operations to be performed. It also should be noted that idle time and the time required for transporting materials can constitute the majority of the time consumed.

Free Form Fabrication

In 1984, the first commercial free-form fabrication system was introduced by 3D Systems. This technology , called stereolithography, and dozens of competing technologies which followed it, create physical objects directly from 3D CAD models, and can be thought as " three dimensional printing." This collection of technologies is often called rapid prototyping. Most of the technologies work by constructing an object, one cross sectional area at a time, by depositing a material or by using a laser to selectively solidify a liquid powder. The resulting parts are most often made from plastics, but other materials are available, including wax, paper, ceramics, and metals. In some cases the parts are used directly for visualization or in working prototypes. However the parts are often used as patterns to make molds or patterns from which parts with particular material properties can then be molded or cast.
