production volumes are very high and there is no product variety
holes are to be bored at precise locations
very small production volumes and product varieties are involved, while accuracy requirements are not very stringent
a moderate production volume is combined with a moderate product variety and contoured shapes are to be cut

Answer 1

Concept:

Computer Numeric Control (CNC) is a computer-assisted process to control general-purpose machining from instruction generated by a processor and stored in a memory system or storage media.
CNC is a specific form of Control system where the position is Principle Control Variable.
CNC machine is best suited when:
- There is batch Production because of their Highly Working
- When there is no Precise Location
- When Production Volume is High with a repeated job making
Advantages of CNC Machine
- Improves machining accuracy.
- Enables complex tasks, detail.
- Creates flexibility in manufacturing.
- Increases safety.
- Boosts production volume.
- Reduces setup-changeover time.
Precise Location Required more Jigs and Fixture which leads Increase in Operating cost
