FUNCTION OF CNC CONTROL PANEL KEYS



FUNCTION OF MDI PANEL KEYS
CNC machines need to perform many different operations as needed, many types of keys have to be used on the computer control panel to perform this type of operation. But it has to use key on the control panel to perform special functions .Any key function on the control panel is different .To operate the CNC you should know the name of each key and their function .The function of each key on the CNC MDI panel is as follows.

 Address and Numeric keys





               1)   A to Z (Address key ) -  This key is used to type the address code into the program

               2)NUMBER KEYS - These keys allow numeric entry. Normally located close to the letter                             keypad, most CNC controls have number keys positioned .

               3)EOB KEY - This key is used when complete the one block with a symbol at the end(;) .

               4) CAN KEY -This KEY is used to cancelled the missed code while typing the program.

               5) DELETE KEY - This key is used to remove the code or block from the program.

               6) INSERT KEY - This key is used to put the typed code into the program in write mode .

               7) ALTER KEY - This key is used to replace the other code with the one in the program.

               8) SHIFT KEY - This key is used to hold the lowercase letter on the address key . That is, 
                              if we assume that we want the small letter V in the Y tab above the address key, 
                          then we have to press Shift + Y= V.

               9) INPUT TAB - This key is used to input the parameter of offset or setting.
  
               10) CURSOR UP /DOWN KEY - This key is used to move the cursor up & down within 
                       the program

               11) PAGE UP/ DOWN KEY - If the program is of multiple pages, then this key is used to 
                                                    jump to the top or bottom page.

              12) RESET KEY - This key is used to clear the alarm when typing a program.
              13) MESSAGE KEY - This key is use ,when an alarm arrives, it checks to see which 
                                                  message the system came from

   Function  key's




        1)CONTROL ON / DRIVE ON - This key is used to turn ON the computer MDI panel.

            2) CONTROL OFF – This key is used to turn OFF the computer MDI panel.

           3)EMERGENCY STOP - This key is used immediately to prevent Machine from
                                      damaging the machine if it is misbehaving.

          4)PROG(Program) -This key is used to view the store program or to insert it into
              the new program system.

          5) POS - Use this key to check the machine's axis position.

          6) OFFSET - Use this key to set offset all types of tool jobs.

          7) DGONS PARAM (Diagnosis Parameter )- This key is used to change the computer
                                  parameters and maintain it.

           8) SYSTEM - This key is used to view files in the system.

           9) AUX GRAPH/GSTM - Use this key to test the program or to test the tool path through
                                    a graph.

           10) OPT STOPIf the M01 code is inserted in the program, then it is kept on .

          11)Z- AXIS LOCK - This key is used if you want to disable axis in the program.

          12)M/C LOCK -This key is used to close all axis.  

          13)AUX LOCK - This key was used to stop the function of the code.

          14) SPDL ON - This key is used to turn ON the spindle .

          15) SPDL OFF - This key is used to turn OFF the spindle.

          16) SPDL DEC/INC - This key is used to decrease /increase the spindle speed.

          17)FEED ON /OFF - This key is used to turn ON/OFF the feed rate.

          18)TOOL DECLAMP - This the key is used to remove the tool in Turret.

           19) FEED OVERRIDE - This key is used to high & lower the feed rate percentage.

           20) CYCLE START /STOP – This key is used to start / stop the program  .


  Mode  Key’s
     1)       REF (Reference ) - This key is used to pass the reference position to all Axis.
   2)       JOG – This key is used to run manually axis .
   3)       EDIT- This key is used to editing in program.
   4)       MDI or MDA(Manual data input ) – This key is used for three function Home position,
                                            tool indexing, spindle rotation.
   5)       INC JOG – This key is used to run axis in micron like 1 , 10 , 100 , 1000 .
   6)       AUTO (Automatic ) – This key is used to run a program in automatic .
   7)       MODE CNC – This key is kept on for run machine operation.
   8)       DNC - This key is used to import programs from outside the computer.
   9)      DRN (Dry run ) – In this mode, the program executes the commands 
                      given in the program rapidly to check.
         10 )SBL – This key is used to run a program block one by one.
   11)  BDL – This key is used to delete the block in the program .
   12)MPG (Manual pulse generator )- In this mode, with the help of a hand wheel,
                    the servo motor operates the axis by manually pulse supply. In this model
         the Axis can be easily moved to 1 micron.
