Virtual Manufacturing
What is Virtual Manufacturring
Virtual manufacturing(VM) is an integrated, synthetic manufacturing environment exercised to enhance all leveles of decision and control in a manufaceturing enterprise. VM can be described as a simulated model of the actual manufacturing setup which may or may not exist. It holds all the information relating to the process , the process control and management and product specific data. It is also possible to have part of the manufacturing plant be real and the other part virtual . Virtual manufacturing is the use puter models and simulations of manufacturing process to aid in design and production of manufactured products.
Lawrence Associate[1996], have identified three different types of Virtual Manufacturing paradigms that use Virtual Reality technology to provide the integrated environment.
(1)Design-centered VM: provides designers with the tools to design products that meet design criteria such as design for X
(2)Production-centered VM: provides the means develop and analyse alternative production the process plans;
(3)Control-centered VM: allows the evaluation of product design, production plans, and control strategy and a means to iteratively to improve all of them through the simulation of the control process.
What is the Significance of VM
VM aims at providing an integrated environment for a number of isolated
