Introduction
Drawing
Drawing may be defined as the representation of an abject by
systematic
lines. Ordinarily, the idea conveyed by the word drawing is a
pictorial view in which
an object is represented as the eyes see it. A pictorial view
shows only the outside
appearance of an object.
Engineering Drawing
Engineering drawing is a graphic language which has its own
rules. It gives
complete description of an object or a machine part as regards
shape, size and all other
internal details from which it can be constructed or
manufactured.
Artistic Drawing
It is the art of representation of an object by an artist as per
his imagination or
by keeping the object before him such as painting, advertisement
board, etc.
Machine Drawing
Machine drawing may be defined as the representation of a
machine
component or machine by lines according to certain set rules. A
machine drawing
generally gives all the external and internal details of the
machine component from
which it can be manufactured. The machining symbols, tolerances,
bill of material, etc.
are specified on the drawing. The-relative positions of the
different components and to
make assembly drawing are also specified. IS: 6961972 is the BIS
Code for
Machine Drawing.
Codes of Practice for Engineering Drawing
In India, IS 696 code of practice for general engineering
drawing was
issued in 1955 and revised in 1960 and 1972. The following are
some of the important
Indian Standard Codes used for machine drawing.

Welded Joints
Welding is defined as the localized, intimate union of metal
parts in the
plastic or plastic and molten state, with the application of
blows or mechanical pressure
or the union of parts in the molten state without any pressure.
There are three main
methods of welding, viz., forge welding, electric resistance
welding and fusion welding
Welding is a permanent method for making joints. Welding has
replaced riveting in
many industries because of saving in labor as well as material
and reduction in weight by
the use of lighter plates and the elimination of all overlaps
and rivets.
Types of Welded Joints and Symbols
There are five basic form of welded joints, namely, edge, butt,
lap, corner and
tee. The various types of welded joints and their symbols have
been shown in Fig1.0.
Butt Joint-This type of Joint is used to join the ends of two
plates, located m the same
plane..
Or 2 to 5 mm thick plates, the open square butt joint should be
selected. But above 5 mm
thickness, the joint with edge preparation on one or both sides
may be recommended.
Lap JointIt is used to join two overlapping plates such that the
edge of each plate is welded to the surface of the other.
This type of joint is suitable up to 3 mm thick plates.
Corner Joint-It is used to weld the edges of two plates this is
suitable for both heavy and
light gauges. This type of joint is commonly used in the
construction of boxes, tanks,
frames and other circular items.

Fig.1.0
Edge joint-The edge joint is used to join two parallel plates.
This is generally used for
sheet metal works.
T-JointT-Joint is used to join two plates, the surfaces of which
are at right angle to each other. It is employed for thickness of
plates up to 3 mm and is widely used in thin
walled structures.
Riveted Joints This is a permanent joint in which sheet metals
or plates are fastened together by means of a special element
called rivet. A rivet is a short round bar of steel or wrought iron
with a head at one end and a tail on the other end. Riveted joints
are widely used in structural work like roof trusses, bridges,
boiler shop and aircraft weapons.
Riveting Process When two plates are to be riveted and joined,
holes are made in the plates. For relatively thin plates, holes are
made by punching operation. But for pressure-vessel joints, the
holes are usually drilled and reamed.

Keys
A key is a small metallic part used to transmit rotary motion
between two parts like a shaft and a pulley. The key is inserted in
the slot which is half way in the shaft and half way inthe pulley.
This slot which takes up the key is called as keyway. The key is
subjected to shearing and crushing forces. Taper 1:100

Keys are used to connect pulleys, couplings, clutches, sprocket
wheels, gears and cutters with their respective driving shaft or
spindle.
Types of Keys
The following are the main types of keys used in engineering
applications,
i. Sunk Key vi. Double head Key
ii. Saddle Key vii. Peg Key
iii. Gib head Key viii. Pin Key
iv. Feather Key ix. Woodruff Key
v. Single head Key x. Spline shaft
(i) Sunk Key
Keys that ate seated partly in the keyway of shaft and partly in
the keyway of other
members like flange, pulley or gears are called sunk keys. Sunk
key may be parallel or
taper. A parallel sunk key has uniform cross-section throughout
its length and fillets at
the corners, as shown in Figure to give proper seating in the
keyway and to avoid sharp
comers. The taper sunk key is also rectangular in cross section.
Its bottom surface is
straight and the top surface is tapered.
a) Parallel Sunk Key b) Taper Sunk Key Proportions for sunk
key:
Width of the key, W = 0.25 D + 2 mm (where, D = Diameter of the
shaft in mm) Thickness of key, T = 0.66 W
Standard taper == 1 : 100 (i.e. 1 unit of thickness reduction
for 100 units of length)

(ii) Saddle Key The keyway cut in the shaft increases the stress
concentration and weakens the shaft. In order to overcome this
problem, saddle keys are used to fit pulley or flange on a shaft
without the provision of the keyway. Saddle key holds the pulley on
the shaft due to friction and it is suitable only for light loads.
.
Saddle keys are of two types namely,
(a) Hollow saddle key
(b) Flat saddle key
(a) Hollow Saddle Key The hollow saddle key shown in Figure 2.20
is of uniform width but tapering in thickness has its taper side
flat. The bottom side is curved to give seating on the shaft. The
two parts like shaft and flange are held only due to friction
between the key and the mating parts.
Proportions of hollow saddle key:
Width of the key, W = 0.25 D + 2 mm
Thickness of key, T = 0.33 D xi. \\ (b)Flat Saddle Key It is
also a taper key that seats with the flat surface formed on the
shaft and fits into the keyway in the flange as shown in Figure.
This key will not be suitable for shafts, which
-

are frequently changing their direction of rotation. The drive
with this key is not rigid and it is suitable for light loads
only.
xii.
Fasteners There are two types of methods to join together parts:
(i) Temporary method,
and (ii) Permanent method. Temporary fastening methods permit
easy separation of the
parts without destroying them. Whereas, permanent fastening
methods do not permit their
separation without destroying the parts. The temporary fastening
methods are
Height of gib head = 1. 75 T
Width of gib head = 1.5 T
iv) Feather Key A feather key is of rectangular or square cross
section with uniform width and thickness as shown in Figure .This
key permits axial sliding movement of the wheel over the shaft when
both of them are rotating together. At the same time the key
transmits twisting moment between the shaft and the wheel. This
type of rotary and sliding movements are needed in certain
applications like gear box.
(iii) Gib Head Key
The gib head key is an ordinary square or rectangular key with a
head that facilitates its removal from the keyway during
dismantling. Gib head keys may be parallel or taper as shown in
Figure. The key is fitted so that there is a clearance between the
interface of the gib head and the outer face of the Binge. An
extractor tool is used in this clearance to remove the key from the
hole.
(v) Single Head Key This is also a feather type of key with a
gib head at one end. This key also permits axial movement for the
wheel over a shaft. The key is fastened with the wheel or pulley by
means of counter sunk screw as shown in Figure .The wheel. Along
with the key can move in the axial direction through the keyway
provided on the shaft.

(i) Temporary fasteners
(a) Threaded fasteners
(b) Non-threaded fasteners
(ii) Permanent fasteners (i) Temporary Fasteners These are
commonly used to join two or more machine parts. In the
temporary fasteners it is possible to separate the fastened
parts without damaging the
fastening elements. Screws, bolts and nuts are examples of
threaded fasteners, and keys and
cotters are examples of non-threaded fasteners.
(ii) Permanent Fasteners These are used to permanently join two
or more parts, which do not require
dismantling in future. In the permanent fasteners it is not
possible to separate the fastened
parts without damaging the fastening dement. Riveted and welded
joints are examples for
permanent fasteners.
Threaded Fasteners
Screw Thread A screw thread is a continuous helical ridge formed
by cutting a helical
groove on a cylindrical shank. Components with such grooves are
called as screws. Screws
are used mainly to fasten two or more parts. They are also used
to convert rotary motion into
translatory (linear) movements. Threads formed on conical
surface are called as tapered
threads. There are different profiles of screw thread, each with
definite proportions. The
terms used in the definition of screw thread are illustrated and
explained below.
,
Nomenclature of Screw Thread Root is the bottom surface joining
the two sides of a thread.
Crest is the top surface joining the, two sides of a thread.
Flank is the surface between the crest and the root of a
thread.
Depth of thread IS the distance between the crest and the root
of a thread measured
normal to the axis of the thread. '
.
Angle of thread is the angle between the Banks measured in an
axial plane.
Helix angle is the angle, which the helix makes at any point
with a plane
perpendicular to the axis.

Nominal diameter is the diameter of the cylindrical rod on which
the threads are cut.
This diameter specifies the size of thread.
Major diameter is the diameter of an imaginary cylinder, which
bounds the crests of
an external thread or the roots of an internal thread. It is
also called as outside
diameter.
Minor diameter is also called as root diameter or core diameter.
It is the diameter of
an imaginary cylinder which bounds the roots of an external
thread or crest of an
internal thread.
Pitch diameter is the diameter of an imaginary cylinder on a
cylindrical screw thread,
which cuts the screw thread in such a way that the width of the
cut thread is equal to
the width of the groove. It is also called effective diameter.
Pitch diameters of both
the external and internal thread are equal.
Fundamental triangle is the imaginary equilateral triangle which
bounds a thread
form.
Pitch is the distance between corresponding points on the
adjacent thread forms
measured parallel to the axis. It may be indicated as the
distance from one crest to the
adjacent crest or from one root to the adjacent root.
Lead is the axial distance through which a screw thread will
advance for one
complete revolution. For single start thread lead is equal to
pitch but for double start
thread lead is equal to twice the pitch.
External thread: A thread cut on the outer surface or the
cylinder is called external
thread. Examples are bolt, stud, and screws.
Internal thread: A thread cut on a cylindrical hole is called as
internal thread. Nuts have
internal thread.

Based upon the number of start points of the threads on the
cylinder, they are classified into
two types.
(i) Single start thread.
(ii) Multi start threads.
Single start thread has only one helical groove on the cylinder.
In this thread lead is
equal to pitch and it is used for general purpose fasteners.
Multi start thread has two or more
helical grooves cut parallel.
A double start thread, for example will have two helical grooves
running parallel and
so there will be two starting points.
Multiple start threads are used when a quick advance is required
in a screwed pair.
That is the translating part should move through a larger
distance for one rotation of the
other part. Multi start threads are generally used in jigs and
fixtures, work holding devices,
fountain pens, toothpaste caps, and so on.
Based upon the slope of the screw thread with the axis, screws
are classified into (i)
Left-hand thread (ii) Right-hand thread
(i) Left-hand Thread If a point on a thread of a screw moves
towards the observer for clockwise rotation of the
screw, then the thread is called as left hand thread. In other
words, a left hand thread is one
which gets removed from a stationary nut when turned clockwise.
A left hand external
thread will be sloping towards the right side when viewed from
the front perpendicular to the
axis. (ii) Right-hand Thread If a point on a threaded screw
moves away from the observer for clockwise rotation of the screw,
the thread is called as right hand thread. A right hand threaded
screw advances into a stationary nut when it is rotated clockwise.
A right .hand external thread will be sloping towards left when
viewed from the front perpendicular to the axis. If no
specification is made the. Thread is considered to be right hand.
Left hand thread is specifically marked.
LIMITS AND FITS Two extreme permissible sizes of a part between
which the actual size is contained are called
limits. The relationship existing between two parts which are to
be assembled with respect to the
difference on their sizes before assembly is called a fit.
ToleranceTolerance is defined as the total permissible variation
of a size. It is the difference between maximum limit and minimum
limit of size.
FITS When two parts are to be assembled the relation resulting
from the difference between their sizes
before assembly is called a fit. The fit signifies the range of
tightness or looseness which may
result from the application of a specific combination of
allowances and tolerances in the design of
mating parts.
-
KIOT/MECH/CAMD LAB

Types of Fits
There are three general types of fit between the mating
parts
1. Clearance fit A clearance fit is one having limits of size so
prescribed that a clearance always results when mating parts are
assembled.
2. Interference fit An interference fit is one having limits of
size so prescribed that an interference always results when mating
parts are assembled.
3. Transition fit A transition fit is one having limits of size
so prescribed that either a clearance or an interference may always
result when mating parts are assembled.
The three types of fits are shown in Figure.
Size: The quantity measure of geometry like length, diameter and
thickness is known as size. Basic size: The theoretical size of a
part derived from the design formulation after rounding off with
respect to the standard size is known as basic size. The tolerances
are always specified to the basic Size. Actual size: It is the size
of a part obtained by measurement after machining process. Nominal
size: The size referred to as a matter of convenience is called
nominal size. Often the terms basic size and nominal size are used
interchangeably. Limits: The two extreme permissible sizes between
which the actual size lies are called as limits.
Maximum limit: The maximum permissible size for the given
basic-size is called as maximum
limit. The greater of the NO limits of size is maximum limit.
Minimum limit: The minimum permissible size for the given basic
size is called as minimum limit. The smaller of the two limits of
size is minimum limit. Tolerance: The amount of permissible
variation to the basic size is called tolerance. The difference
between maximum limit and minimum limit gives the value of
tolerance. If the variation are permit- ted only one side of basic
size (plus side or minus side) then it is unilateral tolerance. If
variations permitted both on the plus and minus sides of basic size
it is called as bilateral tolerance. e

KIOT/MECH/CAMD LAB
13
Deviation: The difference between limit sizes (maximum or
minimum) and the basic size is called deviation. .
Actual deviation: It is the algebraic difference between the
actual size and the corresponding basic size.
Upper deviation: It is the algebraic difference between the
maximum limit of size and the corresponding basic size.
Lower deviation: It is the algebraic difference between the
minimum limit of size and the corresponding basic size.
Fundamental deviation: It is one of the two deviations
conventionally chosen to define the position of the tolerance zone
in relation to zero line.
Zero line: In a graphical representation of limits, a straight
line to which the deviations are referred is called zero line. By
convention, when the line is drawn horizontally, positive
deviations are shown above and negative derivation below it.
Shaft: This term refers to all external features of a part
including non-cylindrical one.
Hole: This term refers to all internal features of a part
including those that are not cylindrical.
Basic shaft: A shaft whose upper deviation is zero is called as
basic shaft.
Basic hole: A hole whose lower deviation is zero is called as
basic hole.
Tolerance zone: It is the zone bounded by two limits of size of
a part on the graphical representation of tolerance. It is defied
by its magnitude and its position in relation to zero line.
Allowances: Allowance is the difference between the basic sizes
of hole and shaft. Maximum allowance is obtained by subtracting the
minimum shaft size from the maximum hole size. Minimum allowance is
obtained from the difference between the maximum shaft size and the
minimum hole size. Allowance may be positive or negative depending
on the type of fit between the shaft and the hole. A positive
allowance denotes clearance and a negative allowance denotes
interference.
