GE6152 ENGINEERING GRAPHICS TOTAL: 75 PERIODS
- To develop in
students, graphic skills for communication
of concepts, ideas and design of Engineering
products
- To expose them to
existing national standards related to technical drawings.
CONCEPTS
AND CONVENTIONS (Not for
Examination) 1
Importance
of graphics in engineering
applications – Use of
drafting instruments – BIS conventions and
specifications – Size, layout and folding of drawing sheets – Lettering and
dimensioning.
UNIT
I PLANE
CURVES AND FREE HAND
SKETCHING 5+9
Basic
Geometrical constructions, Curves used in engineering practices: Conics –
Construction of ellipse, parabola and hyperbola by eccentricity method –
Construction of cycloid – construction of involutes of square and
circle – Drawing of tangents and normal to the above
curves, Scales: Construction of Diagonal and Vernier scales.
Visualization
concepts and Free Hand sketching: Visualization principles –Representation of
Three Dimensional objects – Layout of views- Free hand sketching of
multiple views from pictorial views of objects
UNIT
II PROJECTION
OF POINTS, LINES AND PLANE
SURFACES 5+9
Orthographic
projection- principles-Principal planes-First angle projection-projection of
points. Projection of straight lines (only First angle projections)
inclined to both the principal planes – Determination of true lengths and t ru
e inclinations by rotating line method and traces Projection of planes
(polygonal and circular su rf a ce s ) inclined to both the principal
planes by rotating object method.
UNIT III PROJECTION OF SOLIDS 5+9
Projection
of simple solids like prisms, pyramids, cylinder, cone and truncated solids
when the axis is inclined to one of the principal planes by rotating object
method and auxiliary plane method.
UNIT
IV PROJECTION OF SECTIONED SOLIDS AND DEVELOPMENT
OF SURFACES 5+9
Sectioning
of above solids in simple vertical position when the cutting plane is inclined
to the one of the principal planes and perpendicular to the other – obtaining
true shape of section. Development of lateral surfaces of simple and sectioned
solids – Prisms, pyramids cylinders and cones. Development of lateral surfaces
of solids with cut-outs and holes
UNIT
V ISOMETRIC AND
PERSPECTIVE
PROJECTIONS 6+9
Principles
of isometric projection – isometric scale
–Isometric projections of simple solids and truncated solids
– Prisms, pyramids, cylinders, cones- combination of two solid
objects in simple vertical positions and miscellaneous problems.
Perspective projection of simple solids-Prisms,
pyramids and cylinders by visual ray method .
