#External assessmentSubject Objective

This subject is classified as a Core Technology. It is intended to teach students to

understand facts, concepts and techniques of manufacturing of various items used in

technology areas. This will help the students to discharge the function of supervisor in

industry.

General Instructions

Before the start of practicals every instructor will give :-

- Demonstration of basic tools, machinery equipment marking & measuring instruments

etc.

- Demonstration of various operations to be performed sequentially.

- Explanation of the method of selection of materials (types, quality, quantity, size etc.)

- Demonstration of marking and measuring instruments and their specific use.- Sufficient practice in handling various tools / equipment

- Sufficient practice of various operations.

- Procedure to develop safety awareness on shop floor.

Note :- Job mentioned below are only for guideline any other suitable job can be taken up.

Detailed Content

Theory And Practical Content

1. Wood Working Shop

Any one composite job from the following involving different joints, turning and planing, surfacefinishing by emery paper, varnishing etc. e.g. square stool, tea-poy ,centre table, chourang, table lamp,bed, sofaset, bookrack, cabinet, notice board, show cases, tables, chairs etc.

Note :- One job to be allotted to a group of 2 to 4 student depending on volume of work to be carried out.

2. Fabrication Shop

Including ARC gas, welding gas cutting, remetalling of wornout parts or rebuilding of broken partswith gas welding.- One job, which is having marketability to be selected and performed in a group of 2 to 4 student

depending on volume of works e.g. Waste paper basket, grill, door and window panel, tree guard,

door and window frame, table frame (square pipe 25mm) cooler frame (folding type) etc.- A fitting job need not be a separate activity. It should be practical oriented supporting to other
