Advantages of Numerical Control

Numerical control is greater to conventional developed in a number of ways because of the programmability.

1. The idle time on NC machine tools is reduced that results in lower development time. The machine tool builder tries to design the NC machine where the non-cutting time can be made as low as possible.

2. Parts can be produced more accurately even for smaller batches without any human skill involved in the process.

3. Less scrap is generated in NC machines since the operator is not involved in the actual machining process.

4. The need for expensive jigs and fixtures is reduced or eliminated to a great extent since the geometry is built into the part program.

5.  It is possible to use the general-purpose tools without any special tools.

6.  Manufacturing lead times for the jobs can be reduced to a great extent depending upon the complexity of the job.

7.  The NC machine tool can be utilised continuously, some times even 24 hours, since these are designed for such conditions.

8.  Varying part designs can be easily translated into manufacture with simple changes in part programs.
