The block format to program a circular interpolation with cartesian coordinates is:
N4 G02 (G03) X+/-4.3 Z+/-4.3 I+/-4.3 K+/-4.3
N4 : Block number
G02 (G03) : It defines the interpolation
X+/-4.3 : Coordinate value of the arc’s final point along the X axis.
Z+/-4.3 : Coordinate value of the arc’s final point along the Z axis.
I+/-4.3 : Distance from the arc’s starting point to the center along X axis.
K+/-4.3
: Distance from the arc’s starting point to the center along Z axis.
I,K Must be programmed with a sign. They must be programmed even when their value
is 0.
The block format to program a circular interpolation with polar coordinates is:
N4 G02 (G03) A+/-3.3 I+/-4.3 K+/-4.3
N4 : Block number
G02 (G03) : It defines the interpolation
A+/-3.3 : Angle from the polar arc center to the arc’s final point.
I+/-4.3 : Distance from the starting point to the arc’s center along X axis.
K+/-4.3
: Distance from the starting point to the arc’s center along Z axis.
When a circular interpolation is programmed in G02 or G03, the arc’s center is taken as
the new polar origin. Even when the X axis is programmed in diameters, I is always
programmed in radius.
If, during a G02/G03 movement, the key is pressed, the movement will be performed
at twice the programmed feedrate if P600(3) is zero.
