A Diploma holder(from Mechanical and allied group), irrespective of his field of operation

in an industry, is expected to possess a thorough understanding of drawing, which includes

clear spatial visualization of objects and the proficiency in reading and interpreting a wide

variety of production drawings. Besides, he is also expected to possess certain degree of

drafting skills depending upon his job function, to perform his day to day activities i.e.

communicating and discussing ideas with his supervisors and passing instructions to his

subordinates unambiguously. This course envisages reinforcing and enhancing the knowledge

and skills acquired in the earlier two courses viz. Engineering Drawing –I and Engineering

Drawing-II.

Also Auto CAD software has become an integral part of engineering drawings because of its

ability to draw neat, precise and fast drawing abilities. Knowledge of Auto CAD is need of the

hour. Hence a package on this is a part of curriculum.

Objectives :-

To draw the assembly and details of the given M/C components as specified.

To read and interpret the given production drawings properly.

To prepare the welding drawing as per the conventions.

To make free hand proportionate sketches of identified M/Cs components.

Rationale:

It is one of the important foundation courses. It describes facts, concepts and

techniques of production. It gives knowledge about the various manufacturing processes such

as smithy, forging, turning, carpentry, fitting, plumbing, sheet metal and joining. The

demonstration of CNC machine will give fill of advancement in the industry. There is

improvement of various skills while working on different machines. The understanding of these

processes and skill is helpful to almost all the branches of Engineering.

Objectives:


1. Know the working of various tools used in Carpentry, Smithy, Fitting, plumbing,

welding and sheet metal work section.

2. Use the various tools used in the various sections.

3. Use these techniques in manufacturing various articles.

Term Work:

At the beginning of the term respective instructors should show working of all the

tools and equipments used in their section. Student should draw the sketches of all the tools

used in the workshop in their journal and would write the description and applications of them.

Journal should be submitted along with the other jobs for the final assessment at the end of the

term.
