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
