NC / C N C
Numerical Control (NC) is a method for control of slide motions and auxiliary
motions of machine tools in form of numerical data.
Computer Numerical Control (CNC) is Microprocessor based system to
store and process data for control of slide motions and auxiliary motions of
machine tools.
Development of computer numerically controlled Machine is outstanding
contribution to Manufacturing industry
It has made possible automation of machinery processes with flexibility to
handle as small and medium batch quantities in part production.
Functions of CNC Machines
One or more machine axes slide movements controlled either single of
simultaneously.
Control of feed rate along slide ways and its direction.
Control of spindle rotational speeds (step-less constant surface speed)
Start/Stop of main spindle rotation and change of direction.
Control of coolant, ON/OFF.
Control of tool change, turret head indexing, tool selection, loading of selected
tool from automatic tool changer etc.
Control of numerous other functions e.g. tool wear/breakage monitoring
function, pallet changing, robot loading functions. Also other function related
to operator and/or machine safety system. Software and limit switch
boundaries, chuck guard locks, overload monitoring.
Advantages of CNC Technology:
Due to its flexibility, the machine utilization is very high.
The lead time is very largely reduced thereby prediction of the delivery
schedule is more reliable.
Need of special purpose tooling, jigs and fixtures is mostly eliminated.
Consistency in quality is assured since the manufacture is automatic. This
indirectly reduces the inspection costs.
Handling time is very largely reduced since most of the operations can be
carried out in minimum number of set ups. With facility of automatic tool
changing, pallet change and clamping and unclamping arrangements, the non-
machining time is eliminated to maximum extent.

Since a single machining center can perform many operations, large floor area
is saved which otherwise would be required to install a number of
conventional machines.
Since the input instruction can be easily modified, design changes in the
products can easily be incorporated. This is very advantageous in prototype
manufacture or in manufacture of similar parts in small batch size.
Operator’s skill is no longer important since the accuracy is dependent on the
program. This reduces scrap and rework.
Sudden change in demand can be easily handled because the system has in
built flexibility.
Work in progress, handling time and errors due to a number of set ups, as in
conventional manufacture, are reduced to a very large extent when machining
centers are used.
Since mostly all conditions are under control, the estimation of costs involved
can be done quite accurately.
Disadvantages of CNC Technology:
NC essentially calls for very high investment. But this should be carefully
considered in the light of numerous advantages and over a period of time.
Special skills in programming and maintenance are essential.
Redundancy in labour may be there. But this again needs careful consideration.
When planning for NC, retraining of staff for newer requirements must be taken
into account.
Down time of NC systems is very expensive, therefore, it is very essential that
that staff is adequately trained in operation and maintenance at the supplier’s
place before the machine is delivered.
Part Programming
The preparation of a set of instructions to carry out the machining of a work piece
is called part programming. This work is carried out by a part programmer. He
prepares the planning sheet and writes the instructions in a coded form which is
acceptable to the controller of machine tool. Part programming is of two types:-
Manual
Computer assisted
In the former, the programmer prepares the program and uses the tele type to
prepare the punched tale version of the program. In the later, the tape is produced
by the computer after it has been fed simple instructions in proper format which
are different from the one used in manual part programming. Various symbols used
in programming are given below.

N : Operation sequence number address
B : Preparatory function address
X, Y, Z, A, B, C : Dimension address with axis Identification.
S : Spindle speed address
G : Feed rate address
T : Tool address
M : Miscellaneous function address.
What the programmer has to do?
1. Study the relevant component drawing thoroughly
2. Identify the type of material to be machined.
3. Determine the specification and function of machine to be used.
4. Decide the dimension and more-metric or inch.
5. Decide the coordinate system –absolute or incremental.
6. Identify the plane of cutting.
7. Determine the cutting parameter for the job/tool combination.
8. Decide the feed rate programming – mm/min or mm/rev.
9. Check the tooling required.
10. Establish the Sequence of machining operations.
11. Identify whether use the special features like subroutines, mirror imaging, etc.
is required or not.
12. Decide the mode of storing the part of program once it is completed.
Structure of a Part Program:
A part program defines a sequence of NC machining operations. The information
contained in the program can be dimensional or non-dimensional like speed, feed,
auxiliary function etc. The basic unit of part program input to the control is called a
block. Each block contains adequate information for the machine to perform a
movement and / or functions. Blocks in turn are made up of words. Each word
consists of number of characters. All blocks are terminated by the block end
character.
A block may contain any or all the following:
Sequence or block number (N)
Preparatory functions (G)
Dimensional information (X, Y, Z etc.)
Decimal point (.)
Feed rate (F)
6
Spindle speed (S)
Tool No. (T)
Tool offset function (D)
Miscellaneous functions (M, H etc.)
End of block (EOB).
Block Example
N1234 G.. X.. Y.. S.. M.. F.. T.. D.. LF
The Word Addressed system is method generally use for writing part program for
the numerical control of the wide range of machines. In this system there is an
identifying letter (alpha character) preceding each data? This alpha character in the
world is known as the address, e.g. G2, N2, etc. A control unit recognizes a word
through its address. A number of the word makes up a block and two blocks are
separated by a marker. Generally, the words need not be programmed in a
particular order. Different word may have a different number of digits; some have
only one digits and other may have up to seven digits. Whenever a word represents
machine movement data, a + or a- may be required between the latter and the
number

Programming Modes
To prepare the manuscript for manual part programming, the programmer needs to
collect some data pertaining to the work to be carried out.
The data would be follows:-
• Specification of Machine
• Specification of all tools.
• Specification of work material.
• Speed, feed tables etc.
There are two modes of programming in CNC systems
• Absolute mode
• Incremental mode
Absolute Mode:
Movement is programmed as the complete distance from a specified point, say the
start point or the zero point.
Incremental Mode:
In this mode the movement of the tool, slide or table is described or programmed
as the distance from the end point of the previous mode and must be given the
appropriate negative or positive sign.
Diameter and radius program
Some machines are designed to be programmed in diameter or radius mode.
Programming for diameter is done by input of data in diameter mode. The values
are provided for diameter at different locations as per component deg. The
programming for radius is done by input of data in radius mode and the values are
provided for radius at different locations.
Understanding Program Zero:
Every CNC machine has a reference or machine zero. This is a position that is a
constant to the machine. When a machine is first turned on or powered up by an
operator it must be referenced before any programs can be executed. This is a
process that moves the machine to the zero point on all its axes. These points are
8
set by mechanical limit switches. When the machine reaches these limit switches
the control registers this location as home. This home position is kept by the
control until you turn the power off. Using the home position as a reference you
can now tell the control where on the table you expect it to find the piece to be
worked on. To determine this second work reference point you should first
understand how a CNC machine interprets its direction of movement. All
machining centers move on one or more axes. Assuming the machine is vertically
configured; one with the head directly above the table, the standard set of axes is:
• X (left and right)
• Y (forward and back)
• Z (up and down)
Each axis has two possible directions in which it can travel: + (plus) and - (minus).
This is referred to as the Cartesian coordinate system. The Cartesian coordinate
system can be defined as two or three mutually perpendicular axes which intersect
at a common point called the origin.
Types of motions:
Every CNC machining center has only two types of motion.
Linear
Circular
Linear motion is just as it sounds; straight line movement. These moves can be in
any direction and can include all three axes. A linear move must be performed in
one of two modes. Rapid or feed rate. Which mode the motion is executed is
determined by a preparatory G code. G0 initiates a rapid movement and G1 is
interpreted as a movement at a specified feed rate.
Rapid Linear Motion Example G0 G91 X2.0 Y2.0 Z-2.0
Feed Rate Linear Motion Example G1 F25. G91 X2.0 Y2.0 Z-2.0
The second motion type is circular. A circular motion, in contrast to a linear
motion, can only be performed at a specified feed rate. A circular motion can be a
full circle or it can be just a small segment of an arc. There are two event G codes
used to initiate a circular motion. G2 and G3. The first, G2 tells the control that the
following data should be used to create an arc in the clockwise direction. , G3 is
counterclockwise.
Clockwise Circular Motion Example

G3 X0 Y0 R2.0
Graphical Simulation
It is advisable to verify all programs in memory using the tool path simulation
facility. This will display immediately, any dimensional program errors by
displaying the bar stock being machined step by step on the VDU.
