5. INTRODUCTION
VIRTUAL MANUFACTURING

6.  It is a new kind of manufacturing technology.
 It is based on –
Simulation technology
Virtual reality technology
 Information technology
Virtual Manufacturing system is a computer system which
can generate the same information about manufacturing
system‘s structure, states and behaviors as we can observe
in real manufacturing systems.
VM is used in interactive simulation of various
manufacturing process such as virtual prototyping, virtual
machining, virtual inspection, virtual assembly and virtual
operational system.

7. LITERATURE SURVEY
Prof. Jozef Novák-Marcinčin
Prof. E. Raj Kumar
Heping Li,Xiaoqiu Zheng
P. Depince, D. Chablat, E. Noel, P.O. Woelk

8. WhAT IS VM ?
Virtual manufacturing concepts originate from machining
operations and evolve in this manufacturing area.
Virtual Manufacturing is nothing but manufacturing in
the computer.

9. ChARACTERISTICS
Virtual manufacturing deals with the information and
data of the product and manufacturing system.
Virtual manufacturing is not true manufacturing, but in
the manufacturing of computer and network system
related with software.
Virtual manufacturing processing results are digital
products, rather than the real material products.
Virtual manufacturing is a disperse system.
The simulation of product design, processing and
assembling process can be parallel operated.

10. CLASSIFICATION
Classification based on type of system
integration.
Classification based on types of product and
process design .
Classification based on functional usage

12. DESIGN SIMULATION

13. VIRTUAL REALITY TECHNOLOGY
Virtual Reality is technology for presentation of complicated
information, manipulations and interactions of person with
them by computer.
Virtual Reality is a computer-generated interactive three-
dimensional environment to simulate reality.
Virtual reality with ability to show data 3D and attach sounds
and touch information increases extraordinarily data
comprehensibility.
Virtual reality has entered into the public awareness as medial
toy with equipment „helmet-glove“, which was preferentially
determined for wide public and the price of this system had also
to correspond to this fact, so price could not be very high.

14. VR systems could be divided by ways of
communication with user to such groups:
Window on World Systems
Video Mapping
Immersive Systems
Telepresence

15. METHOds ANd TOOLs UsEd IN
VIRTUAL MANUfACTURING:
Manufacturing characterization
Modeling and representation technologies
Visualization, environment construction
technologies
Verification, validation and measurement
Multi discipline optimization

16. BENEfITs Of VIRTUAL
MANUfACTURING
Quality
Shorter cycle time
Producibility
Flexibility
Responsiveness
Customer relations

17. dRAwBACks
Integration of simulation systems in planning and
design tools
Automatic generation of simulation models
Distributed simulation, optimization and control
Hybrid simulation
Human-computer interfaces
Virtual prototyping

18. sCOPE Of VIRTUAL MANUfACTURING
Virtual manufacturing objectives, scope and domains

19. APPLICATIONS
Airport operations.
Urban traffic operations.
National economy study.
Waging military battles.
Material and warehouse distribution systems study and
development.
Maintenance.
VM for sheet metal processing.
Virtual machine tools.
 Virtual machining and inspection system

20. CONCLUSION
It appears that VM will stimulate the need to design
both for manufacturability and manufacturing
efficiency.
 Nowadays, even if there is a lot of work to do, all the
pieces are in place for Virtual Manufacturing to
become a standard tool for the design to
manufacturing process.
