In the case of circular movements (G2/G3) and thread cutting (G33, G34, G35), the individual
axes must be assigned an interpolation parameter:
0 = No interpolation parameter
1 = Interpolation parameter I
2 = Interpolation parameter J
3 = Interpolation parameter K
Standard MD: X axis .......... I
Y axis .......... J
Z axis .......... K
Several axes may have the same interpolator name.
Programming when using identical parameter names
G2 X5 C10
Assignment: 1st parameter for 1st programmed axis
Axes without an interpolator name cannot execute circular or helical movements or perform
thread cutting.
