RATIONALE:
Engineering graphics is a basic subject for all branches of Diploma Engineering and Technology.
Since engineering drawing is considered as the language of engineers, the Proper understanding
and practice is required with proper instruments. This subject is aimed at providing basic
understanding of the fundamentals of Engineering Drawing; mainly visualization, graphics theory,
standards & conventions of drawing, the tools of drawing and the use of Drawings in engineering
applications. The topics covered are based on the syllabus for Diploma studies in engineering. The
subject is planned to include sufficient practices which would help the student in Visualization of
three dimensional objects and developing the drawing. The chapters are arranged in sequence
and starts from the basic concepts of geometrical constructions & engineering curves, proceeds to
the principles of projection techniques. By the end of the subject it is expected that the students
would be matured to visualize any engineering component by reading an engineering drawing.
COURSE OUTCOMES:
Recognize the drawing tools and key aspects of the Drawing.
Classify and construct the various types of polygons and use correct dimensioning methods.
Identify the uses of various tools and commands in AutoCAD software and apply them to draw in AutoCAD.
Construct the conics and the special curves and their applications. Understand the concepts of Projections of points, lines and solids and know how to use
them to project an object in simple position.

Rationale:
In many fields of Engineering, there are situations where in the effects due to various
factors can be calculated only in a smaller region. To calculate the total effect or effect over a
larger region the Integration concept is used. Integration plays vital role in many fields of

Semester : IV
Subject Code & Name: ECM48 INDUSTRIAL TRAINING – I
The students are expected to gain a working experience in various departments of an
industry / organisation and hence learning the industrial management in a practical way.The
students have to undergo a six months industrial training (PHASE I) during the IV semester in a
related industry / organisation. During the training period the students are 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.
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 - to- day 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, and 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 Organization.

Course Name : DIPLOMA IN ELECTRONICS AND COMMUNICATION ENGINEERING
Semester : VII
Subject Code & Name: ECM74 INDUSTRIAL TRAINING – II
The students are expected to gain a working experience in various departments of an
industry / organization and hence learning the industrial management in a practical way.
The students have to undergo a six months industrial training (PHASE II) during the VII semester
in a related industry / organization. During the training period the students are 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.
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 - to- day 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, drawings etc should be incorporated with the consent of the
Organisation.
