1 Answer

Answer :

Components of CNC machines The various components of CNC system are :-

1) Program Input Device:- It is the medium of transmitting the part program to the computer. Three commonly used program input devices are punch tape reader, magnetic tape reader and computer.

2)Memory Storage :-The control program as well as manual instructions are stored in the memory storage

3)Microprocessor :- It reads the instructions given by memory storage & sends the required signals to the CNC machine tool

4) Machine Control Unit (MCU):- It processes the information received from memory unit, operate and sends appropriate instructions to machine tool.

5) Drive System:- A drive system consists of amplifier circuits, drive motors, and ball leadscrews. The control signals are augmented to actuate drive motors which in turn rotate the ball lead-screws to position the machine table.

6) Machine Tool: -. It always has a slide table and a spindle to control of position and speed. The machine table is controlled in the X and Y axes, while the spindle runs along the Z axis.

7) Feedback System:- It continuously monitor the position at which the cutting tool is located at any particular instant.

8) Programmable Logic Controller (PLC) :-They developed to be re-programmed without hardware changes when requirements were altered and thus are re-usable.

9) Machine Control Panel:-It is the direct interface between the operator and the NC system, enabling the operation of the machine through the CNC system. 

10) Operator Control Panel:-The Operator Control Panel provides the user interface to facilitate a two way communication between the user, CNC system and the machine tool.
