RATIONALE:

We imagine the machine component or structure to be cut by a plane or planes so that most

of the details could be seen. The exterior shape of objects like a connecting rod with elliptical configuration can be conveniently shown by using sectional views. The components parts of a machine and their relative positions will be revealed by the sectionals view of the machine.

The exact size and shape of the sheet to be cut is given by the development of the object

concerned. Most of the sheet metal works in engineering industries involve the development of surfaces of solids like cubes, prisms, cylinders, pyramids, cones and spheres with or without cuts and slots. It is essential that sheet metal technicians have a thorough knowledge of preparing developments of various types of surfaces.

Orthographic projection is possible to describe the shape of any object completely by using

orthographic projections. These orthographic views are required for the manufacture of object and machine parts .Hence it is necessary to study orthographic projections.


One such system of projection is isometric projection which is a type of pictorial projection showing the three dimensions of an object in one view. Isometric view has the distinct advantage of conveying the real shape of the object in such a way that even those who are not familiar with the art of reading a drawing can easily visualize its form and shape.

OBJECTIVES:

•••• Able to show the internal details of an object and true shape section.

•••• Able to achieve the concept of sheet metal fabrication.

•••• Acquire knowledge about clear vision of the various projections.

•••• Conveying the real shape of the object using isometric view.

prescribed form. Students have also to put their signature on the form and submit it to the

institutional staff in-charge. Attendance and submission of Review reports will be duly considered

while awarding the Continuous Assessment mark.

3. Training Reports

The students have to prepare two types of reports:

• Comprehensive report at the end of each phase of Industrial Training will be reviewed while awarding End semester Examination marks.

3.1 Industrial Training Diary

Students are required to maintain the record of day - today work done. Such record is called

Industrial training Diary. Students have to write this report regularly. All days of the week should be

accounted for clearly giving attendance particulars (Presence, Absence, Leave, Holiday etc). The

concerned Industrial supervisor is to check periodically these progress reports.

3.2 Comprehensive Training Report

In addition to the diary, students are required to submit a comprehensive report on training with

details of the organisation where the training was undergone after attestation by the supervisors.

The comprehensive report should be incorporating study of plant/ product /process/ construction

along with intensive in-depth study on any one of the topics such as processes, methods, tooling,

construction and equipment, highlighting aspects of quality, productivity and system. The

comprehensive report should be completed in the last week of Industrial training. Any data,

maintaining an Industrial diary to record their observation and learning. On completion of training, a

training report should be submitted to the Head of the Department. Industrial training of Sandwich

students will be evaluated based on Continuous Assessment of two periodical reviews and an End

semester Examination on Assessment of Training Report and viva-voce.

OUTCOMES:

• Experience the production process in an industrial organization

• Appreciate the Organizational structural and functions of department in industries

• Practice on production machines and its operation/ Maintenance

• Follow safety practices in industries

• Develop social skills and inter personals skills such as planning ,listening

• Appreciate the ethics practiced in industries

• Improve communication skills

• Develop concepts of QC tool practiced in industry such as 5S, JIT, KAIZEN , TQM

SANDWICH DIPLOMA COURSE - INDUSTRIAL TRAINING

1. Introduction

The main objective of the Sandwich Diploma Course is to mould a well rounded technician

acclimated with industrial environment while being a student in the institution.

The Sandwich Diploma Course study is pursued by students, in 7 semesters of 3½ years duration,

the subjects of 3 years - Full Time Diploma Course being regrouped for academic convenience.

While in the 4th semester students undergo Industrial Training-I for 6 months (December through

May). They also do course work in the institution for one day in a week, while in the 7th semester

they undergo another spell of 6 months (June through November) Industrial training-II.

The Apprenticeship (Amendment) Act 1973 is followed in regulating the Industrial training

procedure for Sandwich Course.

2. Attendance Certification

Every month students have to get their attendance certified by industrial supervisor in the

prescribed form. Students have also to put their signature on the form and submit it to the

institutional staff in-charge. Attendance and submission of Review reports will be duly considered

while awarding the Continuous Assessment mark.

3. Training Reports

The students have to prepare two types of reports:

• Weekly report in the form of diary to be submitted to the concerned staff in-charge of the institution. This will be reviewed while awarding Continuous Assessment mark.

• Comprehensive report at the end of each phase of Industrial Training will be reviewed while awarding End semester Examination marks.

3.1 Industrial Training Diary

Students are required to maintain the record of day - today work done. Such record is called

Industrial training Diary. Students have to write this report regularly. All days of the week should be

accounted for clearly giving attendance particulars (Presence, Absence, Leave, Holiday etc). The

concerned Industrial supervisor is to check periodically these progress reports.

3.2 Comprehensive Training Report

In addition to the diary, students are required to submit a comprehensive report on training with

details of the organization where the training was undergone after attestation by the supervisors.

The comprehensive report should be incorporating study of plant/ product /process/ construction

along with intensive in-depth study on any one of the topics such as processes , methods, tooling,

construction and equipment, highlighting aspects of quality, productivity and system. The

comprehensive report should be completed in the last week of Industrial training. Any data,

drawings etc should be incorporated with the consent of the Organisation.
