Chapter 11 Motion Control Instructions
11-271
Example 3:
Specify the center of a circle and conduct a circular interpolation with T in relative mode
Current position (2000, 0), axis parameters: default values, the G codes to be executed:
N00 G91
N01 G17
N02 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.
The Y/X curve for the whole movement process is shown below:
Example 4:
The helical interpolation with the center specified by XY plane
Current position (0, 0), axis parameters: default values, the G codes to be executed:
N00 G17
N01 G91
N02 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 coordinate parameters as the
end points; the circular arc is drawn in clockwise direction; the final motion path is a helical curve.
The projection on XY plane is an half of the circle with the center (100,100).
