Virtual Reality (VR) has emerged as a realistic option in a number of applications, the range and number of which are
increasing annually. It is also being considered as the new future interface for allowing humans to communicate with
computers. This is crucial, when designers and industrial engineers are involved in design activity with the help of
computers. Modern computer-aided design (CAD) systems and software tools have played a significant role in improving
the efficiency of the overall product design process. However, the impact of these technologies is largely restricted to the
detailed modeling and engineering analysis. At the early stages of product design the specifications and constraints are not
been fully established. The industrial designers and engineers need the freedom to change and modify the product
configuration. They also need to investigate the mechanical behavior for a wide range of alternative solutions. Recent
advancements in high-speed computer hardware and VR technology provide opportunities to carry on design, evaluation
and user training before a project is launched. This paper presents evaluation of the concept design and user training in VR
environment. A unique design and simulation is used to illustrate and discusses the role that virtual reality in design,
evaluation and user training.
Keywords: virtual concept design, virtual reality, modeling and simulation, evaluation, user training, deformable
object, B-spline surface.

Manipulators are used for proper alignment of slabs and plates before rolling passes begin. Width is a very important
parameter in rolling of the plate, so a precise and reliable method should be introduced to measure the width of the plate. The
manipulators can be used for the measurement of the width with the help of a rack and pinion arrangement and an encoderdecoder.
In this paper, a method is suggested for the slab width measurement in the existing layout of the plate mill of Bhilai
Steel Plant using hydraulic manipulator. A program in C language has also been developed for design of manipulator pinion
or assistance in design process for the same. The thermal analysis using Solidworks software has been carried for the
manipulator jaw so as to avoid any dimensional distortion of jaw due to high temperature of slab. This also ensures reliable
measurement.
Keywords: Manipulator, rack and pinion, slab.

The Severe Plastic Deformation (SPD) is an effective approach for producing bulk nanostructured material. Equal Channel
Angular pressing (ECAP) processes provide an efficient procedure for achieving ultra fine grained material with excellent
mechanical properties. The objective is to achieve high and homogeneous deformation in the work piece. In this work an
optimized design of the channel die is presented which improves deformations obtained in materials using standard dies.
This is a very useful process which can help in the reuse of bulk materials. It can convert the used bulk material to Ultra fine
