Computer Numerical Control keys

 Machine key: it indicates the key position of machine.

Program key: It shows previously programmed operation

Program manager key: it is used for creating new program and also all programs are stored.

Alarm: it indicates the alarm 🚨 key.

Input key: it is used for entering new blocks in programming.

CNC Control panel:

The main purpose of control panel is to control the cnc machine.

It is also known as operator panel.

Mode selector knob: 

  Memory mode(automatic mode): it is used for executing any program.

SBK[Single Block Mode]: the function of this key is to run the program block by block.

MDI[Manual Data Input]: In this mode we can run the machine manually such as spindle rotation,tool changing, manual lathe operations.

ZRN[Zero Return]: In this mode we can move the turret or tooo to its home position.

Feed Override Knob[Feed Operation]:

It control the movement of tool Range[0%-120%]

Spindle Override Knob:

It is used for controlling speed of the spindle. Range[50%-120%].

SPFOR[Spindle Forward/Clockwise]:

In this mode we can rotate the spindle in forward direction.

We can use this key or we can operate this in JOG mode only.

SPSTOP ]Spindle Stop]: It is used to stop the Spindle.

SPREV[Spindle Resverse]: It is used to run the spindle in counter clockwise or ant-clockwise direction.

SPORD[Spindle Orientation] key: It is used to lock the spindle.

Turret Station key: it indicates tool number.

MPG[ Manual Pulse Generator] Mode:

It is used to move the tool either in x or z axis by using JOG mode.

Execution keys:

CYST[Cycle Start]: it is used to run or start the cycle.

CYSP[ Cycle Stop]: it us used to stop the program or cycle.

RST[ Restart]: By using this key we can start the program repeatedly from the beginning.

Program protect key: it is used to protect the program.

Lubinch[ Lubrication Inching]: the purpose of this key is to check the lubrication pressure (15kgf/cm^2).

OSP[ Optional Stop]: This is used to stop the program optionally.

BDT[Block Delete Key]: it us also known as block skip key, used for skiping the unwanted blocks of code.

CLON[Coolant On] key: used to switch on the coolant manually.

CLOFF[Coolant Off] key: used to switch off the coolant manually.

Tailstock keys:

TSOUT[Tailstock Out]: In this we can move the tailstock quil outside.

TSIN[Tailstock In]: In this we can move tailstock inside.

TRST[Turret Station]: it is used to move the tools or turret manually for required tool.

Emergency Stop Button: the function of this key is to stop the machine in emergency condition.
