What is JOG mode in CNC ?

 
           JOG mode is also called jogging mode. In this mode, the CNC machine is used to operate manually. This mode is used to make the CNC machine much faster. In this mode, the CNC machine carriage can be travel. This the mode is used to manually perform the Mainly Three function;

        1) Movement of Axis
         2) Tool Indexing
         3) Spindle rotation.

          1] MOVEMENT OF AXIS - In this, we have the CNC lathe used to move the X and Z axis in the machine as well as the X, Y and Z axis in the milling machine. We will see below how this is done.


To move simply

Step 1- Press “ JOG” Key

Step 2-  Press axis “ +X/+Y/+Z or –X/-Y/-Z “ if you want to move. some machine it can be only “ X/Y/Z” not give in + or -. That time we have need following step 3 after pressing axis.


Step 3- Press “ + OR –“ to move the axis.



To move rapidly

Step 1 – Press “JOG” key

Step 2 – Press “ Rapid + (+X/+Y/+Z or –X/-Y/-Z)”.Some machine it can be only “ X/Y/Z” not given + or - . That time we have need following step 3 after pressing axis.


Step 3 - Press “ + OR –“ to move the axis .


        2]  TOOL  INDEXING – In  MDI mode we used tool no. and tool offset no .(T0100 OR T0202). But in this case, we can change tool directly.



           Step 1 – Press “ JOG” key.

           Step 2 – Press “ TOOL” key.


3] SPINDLE ROTATION -  In MDI mode we used programmable code (G97 S200 M03). But in this  case we can rotate spindle directly 

         Step 1 – Press “ JOG” key.

         Step 2 – Press “SPDL CW / SPDL CCW” (spindle clockwise/ counter clockwise)
