3.2.2.3 G02 Circular interpolation, clockwise, G03 Circular interpolation, counterclockwise
Definition of a circle or segment of a circle, clockwise or counterclockwise,
with linear positioning of a linear axis (helix) or expanding radius (spiral)
with additional positioning of a linear axis (conical helix).
)
Note!
When correction modules are used (e.g. TRC) only the normal arc
can be programmed. The additional functions are not allowed!
G02 AXES D I J K R F E L
G03 AXES D I J K R F E L
AXES Target point coordinates of the three linear principal axes (default X,Y,Z), as
well as start or target point coordinates of the three rotative secondary
axes (default A,B,C).
D Radius change on reaching the target point
I Center coordinates of the first principal axis (X) or number of additional full
circles
J Center coordinates of the second principal axis (Y) or number of additional
full circles
K Center coordinates of the third principal axis (Z) or number of additional
full circles
R Interpolation radius
F Path speed
E, L Selection of feed speed via speed (E) and increment (L). F=E*L.
With G02/G03, the interpolation on a circular path is programmed in the
selected plane (G17, G18 or G19) (G02 clockwise, G03 counterclockwise).
)
Note!
It is always necessary to select a plane; there is no standard
default setting!
To determine an arc, you need to specify three points. These are always the
arc start point and arc end point, as well as either a center or a radius. This
results in the following mandatory DIN address combinations for the
determination of an arc, depending on the plane
G17: "XY IJ" or "XY R"
G18: "ZX KI" or "ZX R"
G19: "YZ JK" or "YZ R"
The target values can be specified both in absolute dimensions and in
incremental dimensions.
