Virtual manufacturing (VM) is the use of computers to model, simulate and optimize the critical operations and entities in a factory plant. Virtual manufacturing started as a way to design and test machine tools but has since expanded to encompass production processes and the products themselves. The main technologies used in VM include computer-aided design (CAD), 3D modeling and simulation software, product lifecycle management (PLM), virtual reality, high-speed networking and rapid prototyping. Virtual manufacturing provides an organization with the ability to analyze the manufacturability of a part or product as well as evaluate and validate production processes and machinery and train managers, operators and technicians on production systems. There are three main subcategories of VM:

3. INTRODUCTION:-
• A virtual manufacturing System is the use of computer to model
stimulate and optimize the critical operations and entities in factory.
• It is started as a technique to manufacture and test the machine
tools.
• But has been expanded to accomplish the production process and
products themselves.

4. WHY VM…………..?
• We have been evaluating the technology or techniques for manufacturing,design of
products.
• We stopped drawing by using pencils in late 1960s only die to the invention of drafting tools
like CAD.
• Now a days more techniques are available from designing of products to manufacturing of
products like CATIA ANSYS Solid works etc…,
• But growing industrial revolution 4.0 needs more advanced system than this like virtual
manufacturing.

5. EVOLUTIONOFVM
V P L
They are the first one’s to develop VR
and joron lanier is condidered as father
of VR.
IT was the first company to manufacture
and sell the vr systems commercially.
UNITED STATES Defence department
became the first organization to
implement the virtual manufacturing
System.

7. Virtual Reality:-
 It is an computer interactive generated experience within
certain region of simulation.
 It also involves feed back system.
 This immersive environment system may be real or fanthastic.

8. Augmented Reality
 Augmented reality (AR) is an interactive experience of a real-
world environment.
 where the objects that reside in the real-world are augmented
by computer generated perceptual information.
 It is recently getting employed in Google maps.

9. Product Library
 It consists of all the product data that has to be manufactured by the firm.
 It uses VRML software for its products development.
 It gives the data of the product to the designer based on his requirement.

13. TYPES OF VIRTUAL MANUFACTURING
• Design centered
• Production centered
• Control centered

14. Design centered:-
• It gives data about manufacturing processes to the
engineer’s and designers.
Production centered:-
• It simulates the production process so that they
can be tested and optimized.
Control centered:- • It simulates the controls that are used to run the
actual production process.

15. PRO’S:-
• It decreases the distance between lab and reality.
• The machining costs and testing costs will be reduced.
• It helps to reduce the mistakes in precision process.
CON’S:-
• It involves installment of new equipment.
• It also requires the high skilled engineer’s to control this
system.

16. CONCLUSION
• Whatever the technology we are using or developing is just to know the real
situation in lab itself.
• Hence by using this system we can reduce the distance between lab and reality.
