RESEARCH LABORATORIES

Engineering Workshop-I&II

Mechanical Engineering Workshop is a place where students acquire knowledge on the operation of various processes involved in manufacturing and production. The Workshop Practice course makes the students competent in handling practical work in engineering environment.  It consists of different trades in which the students get trained for gaining confidence on basic engineering practices in I B. Tech itself.

FITTING SHOP

Fitting shop is a place where fitting or assembling work is carried out. Some repair /   maintenance and Die punch work is also carried out in Fitting shop.

CARPENTRY SHOP

The wood is obtained from the trees. In Woodwork shop students are trained to work on wooden jobs by using various hand tools  such as claw hammer, chisels,  mortise chisels, mallet, hand saw, backsaws, coping saw, block plane, jack plane, saw horse,  workbench, router table, utility knife, tin snips, nail puller, speed square and drilling machine.

BLACHSMITHY PRACTICE

The Mechanical working of the metal is the shaping of the metal in either cold state or hot state. This does not include machining, grinding or casting. But in Mechanical working of the metal, the metal is shaped by “pressure” actually, in which forging, bending, twisting, drawing etc are done bring it to its final shape. In these processes some metals are shaped in both cold and hot worked.

FOUNDRY PRACTICE

Foundry is one of the manufacturing process by which a desired shape of metal is obtained by heating up to its molten state (liquid state), and pouring into mould cavity. After some time metal is allowed to cool and solidify. The solidified piece of metal is known as casting.

TINSMITHY

Many engineering and house articles such as boxes, cans, funnels, ducts etc. are made from a flat sheet of metal. The process being known as tinsmithy. For this the development of the article is first drawn on the sheet metal, then cut and folded, to form the required shape of the article. Allowance should be given in the drawing stage for folding and bending. This allowance depends upon the radius of the bend and thickness of the sheet metal.

MACHINE SHOP

Machine shop is a place in which metal parts are cut to the required size and put together to form mechanical units or machines. The machines so made are to be used directly or indirectly in the production of necessities and luxuries of civilization. Machine shop is the base of all mechanical production

WELDING SHOP

In addition this lab provides basic knowledge of the phase’s formation which related to various heat treatment processes.

The Primary focus of the Metallurgy and Material science program is to provide undergraduates with a fundamental knowledge based associated materials properties, and their selection and application. Upon graduation, students would have acquired and developed the necessary background and skills for successful careers in the materials-related industries. Furthermore, after completing the program, the student should be well prepared for management positions in industry or continued education toward a graduate degree.

CADD & MAT Lab

To acquaint the student with some of the terminology in this very new field and relate it to the basic engineering process .To provide an introduction to the basic analytical fundamentals that are used to create and manipulate geometric models in a computer program. To introduce the student to full-scale CAD software system designed for geometric modeling of engineering components and systems( Attention will be directed at both drafting and full 3-D modeling systems).To provide experience in using the CAD tools to develop a simple project of reasonable complexity. To provide a brief survey of methods for integrating these tools into a comprehensive design system that incorporates advanced data base management concepts

CAD/CAM Lab

Computer Aided Drafting is a process of preparing a drawing of an object on the screen of a computer. There are various types of drawings in different fields of engineering and sciences. The use of CAD process provides enhanced graphics capabilities which allows any designer to • Conceptualize his ideas • Modify the design very easily • Perform animation • Make design calculations.

  1. Increases the productivity of the designer
  2. Improves the quality of the design
  3. Create data base for manufacturing: In the process of creating the documentation for these products etc

Computer-aided manufacturing is the use of computer-based software tools that assist engineers and machinists in manufacturing or prototyping product components.

Fluid Mechanics & Hydraulic Machines Lab

This course will provide practical knowledge in verification of principles of fluid flow and imparts knowledge in measuring pressure, discharge and velocity of fluid flow major and minor Losses.
