The G02 command is used to move the cutting tool of the machine using circular interpolation, so that the movement to the end point specified in the block is carried out in an arc (circle) in the clockwise direction.

The use of this command is used directly to process the material with a machine tool.

The movement speed of the cutting tool when executing the G02 command is set by parameter F, during the execution of the control program, the numerical control system (CNC) always uses the last value of the specified feedrate F, until the F command is detected, which has a different numerical value.

The center is most often identified using I, J, or K to define the relative offset from the starting point of the arc to the center. Here is a typical clockwise arc:

 

   

    G02 => Circular Motion
    X10 Y7 => End Position

    I-5 => X offset to Center Point

    J-10 => Y offset to Center Point
