CNC IntroductionA numerical controlsystem in which the data handling, control
sequences,and response to input is determined by an on-boardcomputer system at the machine tool.
Apllications of CNCCNC is widely used for:- lathe,
drill pressmilling machine grinding unit laser sheet-metal press
Elements of CNC MachineInput Device
Machine Control Unit
Machine Tool
Elements of CNC MachineInput Device:- In computing, an input device is a peripheral (piece of computer
hardware equipment) used to provide data and control signals to an information
processing system such as a computer or information appliance. Examples of input
devices include keyboards, mouse, scanners, digital cameras
Machine Control Unit:- The machine control unit (MCU) is the heart of a CNC system. It is
used to perform the following functions: To read the coded instructions. To decode the
coded instructions. To implement interpolations (linear, circular, and helical) to generate
axis motion commands
Machine Tool :-machine tool is the mechanical device that perform actual machining
operation like- cutting ,drilling., facing, milling, knurling, grindin etc
How CNC WorksControlled by G and M codes.These are number values and co-ordinates.Each number or code is assigned to a particular
operation.Typed in manually to CAD by machine operators.G & M codes are automatically generated by the
computer software.
Programming Key LettersO - Program number (Used for program identification) N - Sequence number (Used for line identification) G - Preparatory function X - X axis designation Y - Y axis designation Z - Z axis designation R - Radius designation F – Feed rate designation S - Spindle speed designation H - Tool length offset designation D - Tool radius offset designation T - Tool Designation M - Miscellaneous function

Cutting tools and its CharacteristicsCutting tool is a device, used to remove unwanted
materials from given work piece for carrying out the machining process, cutting tool is fundamental and requirement
A cutting tool must have the following characteristics: Hardness Hot Hardness Toughness
Types of Tool materialsHigh Speed Steel (HSS)High Carbon Steel (HCS)Cast AlloyCemented CarbideCeramicDiamondCobalt
InsertsInserts are removable cutting tips, which
means they are not brazed or welded to the tool body.
The strength of the inserts also depends upon the shape of the inserts.
Advantages of CNC i. - Easier to program;
ii. - Easy storage of existing programs;
iii. - Easy to change a program
iv. - Avoids human errors
v. - CNC machines are safe to operate
vi. - higher productivity, better quality
vii. -Volume of production is very high
viii. -Less paper work
Disadvantage of CNC
i. -Costly setup, skilled operators
ii. - Computers, programming knowledge required
iii. - Maintenance is difficult
