Expanding mechanical design and fabrication horizons

The capability to develop prototype hardware systems is improving steadily as computer technology is dramatically enhancing design, fabrication proces ses, and tools. Designers now make extensive use of sophisticated 3D solid modeling programs to visualize design concepts, perform engineering analysi s, and communicate detailed design data through networked file transfers. N umerically controlled computerized machine tools are then programmed using the design data to produce parts faster and with greater accuracy than ever before. New laser machining, electrical discharge machining, and rapid pro totyping technology are enabling the fabrication of small, precision compon ents not possible using traditional methods. The result is faster product d evelopment cycle times and lower costs.
