VIRTUAL REALITY

• virtual reality (VR) or virtual environment (VE),
  computer-generated environment with and within
  which people can interact. It is an artificial
  environment that is created with software and
  presented to the user in such a way that the user
  suspends belief and accepts it as a real
  environment.
• The advantage of VR is that it can immerse people
  in an environment that would normally be
  unavailable due to cost, safety, or perception
  restrictions. A successful VR environment offers
  users immersion, navigation, and manipulation.
• Some of the more realistic effects are achieved
  using a helmet like apparatus with tiny computer
  screens, one in front of each eye and each giving
  a slightly different view so as to mimic
  stereoscopic vision. Sensors attached to the
  participant (e.g., gloves, bodysuit, footwear)
  pass on his or her movements to the computer,
  which changes the graphics accordingly to give
  the participant the feeling of movement through
  the scene.

VIRTUAL REALITY

• Computer-generated physical feedback adds a
  "feel" to the visual illusion, and
  computer-controlled sounds and odors reinforce
  the virtual environment. Other VR systems, such
  as flight simulators, use larger displays and
  enclosed environments to create an illusion.
  Less-complicated systems for personal
  computers manipulate an image of
  three-dimensional space on a computer screen. In
  a virtual network many users can be immersed in
  the same simulation, each perceiving it from a
  personal point of view. VR is used in
  some electronic games, in amusement-park
  attractions, in military exercises, and to
  simulate construction designs. Experimental and
  envisioned uses include education, industrial
  design, surgical training, and art.

• Virtual manufacturing (VM) may play a significant
  role in distributed manufacturing, since it may
  improve design critiquing and process planning.
  These improvements will result in better designs
  and more informed partner selection. Furthermore,
  VM is expected to support distributed design if
  it provides protocols and computer aids for
  negotiation.

VM APPROACHES

• Evaluating the manufacturability of a proposed
  design involves determining whether or not it is
  producible with a given set of manufacturing
  operations---and if so, finding the associated
  manufacturing efficiency.
• Distributed manufacturing is performed by virtual
  enterprises. A virtual enterprise is a
  partnership of companies that forms in response
  to a certain market opportunity. The partners,
  who may geographically distributed and of various
  sizes and technical sophistication, contribute
  their core competence to the enterprise,
  enhancing its ability to deliver high quality,
  cost effective products to the market in a timely
  fashion.
• Distributed design is performed by multiple
  designers who may be distributed geographically
  and who employ heterogeneous design support
  systems.

• Design-Centered
• Production-Centered
• Control-Centered

Addition of simulations to control models and
actual processes, allowing for seamless
simulation for optimization during the actual
production cycle.

Multi Enterprise Layer
Company 2
VR is applicable at these 3 layers
Enterprise Layer
Shop Floor
Cell Layer
15

• Detail planning and building of the production
  system (Delmia example)

Enterprise Layer

• 6 manual work stations are realized.

• The cycle time is reduced to 105 seconds.

• Estimated costs for engine are not exceeded.

16
Shop Floor
The purposed design and processes can be
simulated directly in the virtual environment in
order to verify applicability of the proposal
17
Cell Layer
VR can also directly simulate the cells which are
the machines for example a CNC machine can be
programmed and tested virtually prior the real
action for verification.
