This document discusses CNC machines. It describes a CNC machine as a computer-controlled machine that can machine materials to meet specifications using programmed coded instructions without direct human operation. It lists some applications of CNC machines as improving precision, accuracy, and integrating production processes on a single machine to boost output and reduce costs. The document outlines advantages such as increased productivity, accuracy, flexibility and safety, and reduced costs and time. Disadvantages include high initial machine and tooling costs and more complex maintenance.

4. C.N.C Machine :
Computer Numerical Control is the automated
control of machining tools by means of a
computer. A C.N.C is the machine process piece of
material to meet specification by coded
programmed instructions and without a manual
operator directly controlling the machining
operation.

6. APPLICATIONS OF CNC
 In the manufacturing application of digital technology
CNC machining has been focusing on the improvement
of the precision and accuracy of material processing ,
as well as the improvement of the operating process, so
that most production process can be completed on one
machine , thereby improving overall production and
reducing costs.

7. ADVANTAGES
1. Increases productivity
2. High accuracy and repeatability
3. Reduced production cost
4. Reduced indirect operating cost
5. Complex machining operation
6. Greater flexibility
7. Short production time
8. Higher human operator safety
9. Short inspection time and high quality product

8. DISADVANTAGES
1. High machine cost
2. Complicated maintenance
3. High tooling cost
4. Reduce human operator
5. In case of breakdown a lot of complication has to be
faced
