7.11 CIRCULAR INTERPOLATION IN G112
The circular interpolations G2/G3 on the front surface (G112 active) can be programmed in two ways :
- Coupling the value of radius R to the co-ordinates of end of interpolation X and C (method most
commonly used).
- Coupling the incremental co-ordinates of the distance from the circle centre to the interpolation starting
point I and J to the end of interpolation co-ordinates X and C ( I is referred to axis X, J is referred to
axis C)
Example:
G2 o G3 X….. C….. R…..
G2 o G3 X….. C….. I….. J……
