Advantages and Disadvantages Of CNC Machine.(Science and Technology)

 Advantages of CNC Machine:

 1. Greater accuracy of job is achieved.
2 . Higher repeatability and improved product quality.
3. Less operator skill is required to run CNC machine.
4. Better machine utilization hence reduced idle time.
 5. High production rate as speed, feed, depth of cut are optimum for highest quality
6. Lower tooling cost, per piece in production.
7. Jig 's and fixture's cost are often reduced. 8. Reduced cycle time.
 9. Better tool life and machineability.
 10. Less scrap thanks to consistent accuracy, less errors.
 11. Excellent reliability as dimensions are supported programes.
 12. Reduced in - process inventory of parts in process.
13. Design changes are possible. Any change in design is possible at lowest cost.
14. Use of programmable software like Ideas. Master - Cam, Pro - engineer, Edge Cam  etc. for sophisticated jobs.
 15. Productivity are often improved to great extent.
16. CNC machines could also be utilized altogether three shifts to scale back the value of machinery.
17. Tool setup time are often reduced.
 18. Two or more machines are often controlled with one monitor.
19. best suited for continuous and better production.
20. Program are often stored and used again when required.
21. Optimum speed and feed for best surface finish are often used.

Disadvantages of CNC Machine:

 1. CNC machines are more complex machines.
 2 . Cost is high.
3. Cost of control systems used is high.
4. Maintenance cost is high.
