 Example 3: Specify the center of a circle and circular interpolation with T in relative mode
Current position (2000, 0), axis parameters: default values, the G codes to be executed:
N0 G91
N1 G17
N2 G2 X-2000 Y2000 I0 J2000 T3
After G codes are executed, the path of the circular arc is 3 circles plus thick 1/4 of a circle and the Y/X
curve for the whole movement process is shown below:

 Example 4: The helical interpolation with the center of a circle specified by XY plane
Current position (0, 0), axis parameters: default values, the G codes to be executed:
N0 G17
N1 G91
N2 G2 X200 Y200 Z200 I100 J100 E+10000 E-20000 F1000
Instruction explanation:
While G2 is being executed, axis regards 0 as the start point and axis parameters as the terminal
points; produces the circular arc in clockwise direction; finally the motion path is helical curve. The
projection on XY plane is an half of the circle with the center of a circle (100,100).
