CNC Computer Numerical Control

A CNC system receives numerical data, interpret the data and then control the action accordingly by an on-board computer system at the machine tool.

CNC machine is an outstanding contribution to the manufacturing industries. It has made possible the automation of the machining process with

flexibility

CNC Introduction

A CNC machine consist of following 6 major elements:

i. Input Deviceii. Machine Control Unitiii. Machine Tooliv. Driving Systemv. Feedback Devicesvi. Display Unit

Elements of CNC Machine

Block diagram of CNC Machine

The CNC systems are constructed with a NC unit integrated with a PLC .

1. The NC controls the spindle movement and the speeds and feeds in machining. It calculates the traversing path of the axes as defined by the inputs.

2. The PLC controls the peripheral actuating elements of the machine such as solenoids, relay coils, etc.

Working together, the NC and PLC enable the machine tool to operate automatically.

Technology used-

Basic components of NC system

What does ‘PLC’ mean?

A PLC matches the NC to the machine.

A PLC is an industrial computer used to monitor inputs, and depending

upon their state make decisions based on its program or logic, to control

(turn on/off) its outputs to automate a machine or a process.

Part program: A computer program to specify

Which tool should be loaded on the machine spindle? What are the cutting conditions (speed, feed, coolant

ON/OFF etc.)? The start point and end point of a motion segment? How to move the tool with respect to the machine?

CNC programming

Controlled by G and M codes. These are number values and co-ordinates. Each number or code is assigned to a particular operation.

How CNC works ?

Common Format of a Block

1. Machining e.g. milling, drilling, turning, boring, grinding, laser cutting

2. Gear shaping3. Press working4. Welding5. Tube bending6. Assembly7. Coordinate measuring machine

Applications

1. Higher productivity

2. Easier to program

3. Reduced manpower

4. Just in time (JIT) manufacture

5. Improved quality control -Avoids human errors

Advantages of CNC

1. Costly setup

2. Skilled operators-finding and training of NC personnel.

3. Maintenance is difficult
