OBJECTIVES:
 To make the students understand and interpret drawings of machine components so as to prepare
assembly drawings either manually and using standard CAD packages.
 To familiarize the students with Indian Standards on drawing practices and standard components.
 To draw various thread forms, different types of fasteners, Keys, Cotters, Knuckle and Riveted joints.
 To draw principal views, sectional views and two dimensional assemble views of different
components with an emphasis by applying general projection principles using Computer Aided
Drafting (CAD).
 To gain practical experience in handling 2D production drawings including assemblies and 3D
geometrical modeling using software systems.

DRAWING STANDARDS
Code of practice for Engineering Drawing, BIS specifications – Welding symbols, riveted joints, keys,
fasteners – Reference to hand book for the selection of standard components like bolts, nuts, screws, keys etc.
2-D DRAWINGS
Limits, Fits – Tolerancing of individual dimensions- Specification of Fits- Manual Preparation of production
drawings and reading of part and assembly drawings.

CAD PRACTICE (USING APPLICATION PACKAGES)
Drawing, Editing, Dimensioning, Plotting Commands, Layering Concepts, Hatching, Detailing, Assembly,
basic principles of GD&T (geometric dimensioning & tolerance)

ASSEMBLY DRAWING (MANUAL & USING APPLICATION PACKAGES)
Manual parts drawing and preparation of assembled views given part details for components followed by
practicing the same using CAD packages. Suggested Assemblies: Shaft couplings – Plummer block – Screw
jack – Universal Joint – Machine Vice – Stuffing box- safety Valves - Non-return valves- Connecting rod -
Piston and crank shaft- Multi plate clutch- Preparation of Bill of materials and tolerance data sheet.
Use of standard CAD application packages is recommended from the point of view of requirement by
industries. However to encourage our national efforts in indigenous development of software packages with
focus on open source, students may be encouraged to work with “CollabCAD Software”, developed by:
National Informatics Centre (CAD Group), Govt. of India, A-Block, C.G.O. Complex, Lodhi Road, New
Delhi 110003, 2003” www.collabcad.com
TOTAL: 60 PERIODS
