The process of producing components to final net-shapes is fast becoming a desirable goal for metal working industries. This is due to a combination of factors such as the development of new materials and escalating energy costs. This book addresses the design, analysis and simulation of near net-shape operations using some of the most advanced computer techniques and tools available. Topics covered include: sheet metal forming operations: progressive stamping, fine blanking, nesting, flat pattering, bending and nibbling; die design, construction and NC programming of wire EDM; bulk metal forming processes such as cold upsetting and close-die forging; injection mould design, analysis and simulation; computer-aided design of CNC machines for near net-shape operations; and intelligent progressive die design system IPD. This collection of the latest developments from experts in the field should be of interest to practising engineers, graduate students and researchers of metal forming, stamping, mould and die design.6.2.1 Composition of a universal CNC control system Many types of CNC machines are used in near net-shape operations. ... control sub-systems (e.g., positioning, velocity and pressure control sub-systems) that have feedback elements, amplifiers, ... and printing data, offline programming, simulation and connection with the computer management system in a factory. 10 1 - Machine, 2 - Power supply, 3 - Execute components, 4 - Control valves/Driving controller, 5 - Amplifier, anbsp;...
