This review paper describes in general the use of VR as a training tool in manufacturing
technology like design, rapid prototyping, and manufacturing with some practical
examples where VR is used and its benefits in manufacturing industries which reduces
a lot of cost in the design stages to the finish stages. VR is the closest man can get to
reality as the names implies with the present capabilities. The technique enables
engineers and designers to move around and interact with the object in real time. This
review paper looks into some challenges of VR applications in manufacturing
industries.
