Figure 1-14 Example for center point and aperture angle
N5 G90 Z30 X40 ; Starting point circle for N10
N10 G2 K10 I-7 AR=105 ; Opening angle and center point
Note
Center point values refer to the circle starting point!
1.3.5 Circular interpolation via intermediate point: CIP
Functionality
The direction of the circle results here from the position of the intermediate point (between
starting and end points). Specification of intermediate point: I1=... for the X axis, K1=... for
the Z axis.
CIP remains active until canceled by another instruction from this G group (G0, G1, ...).
The configured dimensional data G90 or G91 applies to the end point and the intermediate
point.
