OUTLINES

It is a new kind of manufacturing technology.

It was first introduced by the US department of defense in the year 1994.

It is based on – Simulation technologyVirtual reality technologyAugmented reality technology Information technology

INTRODUCTION

SIMULATION TECHNOLOGY

Flight simulator Driving simulator

VR is all about the creation of a virtual world that users can interact with.

VR is a computer-generated interactive three-dimensional environment to simulate reality.

VR has entered into the public awareness as medial toy with equipment “helmet-glove”.

Example-google card-board, oculus rift , HTC vive etc.

VIRTUAL REALITY

Computerized virtual reality

Advance than VR. It does not takes completely to the virtual world . It creates new things in the existing space . Example :- microsoft hollow lens , google glass.

Augmented reality

Virtual Manufacturing is nothing but manufacturing in the computer.

VM involves the simulation of a product and the processes involved in fabrication.

VM is defined to be an integrated, synthetic manufacturing environment exercised to enhance all levels of decision and control.

What is VM ?

o Design-centered Virtual designing Virtual prototypingo Production-centered Virtual machining Virtual assembly Virtual control qualityo Control-centered Virtual planning Virtual production simulation Virtual training

PARADIGMS OF VM

METHODS :

• Manufacturing characterization• Modeling and representation technologies• Visualization, environment construction technologies• Verification, validation and measurement

METHODS AND SIMULATION TOOLS USED IN VM

SIMULATIONS TOOLS

Manufacturing level

Type of simulation Simulation targets

Factory / shop floor- Flow simulation- Business processsimulation

- Logistic and storage- Production principles- Production planning and control

Manufacturingsystems /manufacturing lines

- Flow simulation - System layout- Material flow- Control strategies- System capacity- Personnel planning

Manufacturing cell /Machine tool / robot

-Flow simulation- Graphical 3Dkinematics Simulation

- Cell layout- Programming- Collision test

Components - Finite-ElementsAnalysis- Multibody simulation- Bloc simulation

- Structure (mechanical andthermal)- Electronic circuits- Non-linear movementdynamics

Manufacturingprocesses

- Finite-Elementsanalysis

- Cutting processes: surfaceproperties, thermal effects, toolwear / life time, chip creation- Metal forming processes:formfill, material flow (sheetmetal), stresses, cracks

The vision of Virtual Manufacturing is to provide a capability to make it in the computer .

VM provides a modeling and simulation environment such that the design , analysis and fabrication/assembly of any product includingthe associated manufacturing processes which can be simulated in the computer.

VISION OF VM

Automotive domain

Aerospace domain

Healthcare domain

Home Appliance domain

Virtual Teaching Platform of Digital Design andManufacturing

Virtual Training

APPLICATIONS OF VM

FEWER PROTOTYPES LESS MATERIAL WASTE REDUCED COST OF TOOLING CONFIDENCE IN MANUFACTURING PROCESS IMPROVED QUALITY REDUCED TIME TO MARKET LOWER OVERALL MANUFACTURING COST
