G03 - Counterclockwise Circular Motion at
Feed
G03 sets counterclockwise circular interpolation as the modal condition. Either program
the arc's endpoint and center coordinates, or program the arc's endpoint and radius.
Refer to Example—Program Arc with Endpoint and Center Coordinates, on page 2 - 7 and
Example—Program Arc with Endpoint and Radius, on page 2 - 8 for programming
examples.
Default—No
Modal—Yes
Cancels G00, G01, or G02
Example—Program Arc with Endpoint and Center
Coordinates
This method requires you to define the arc's endpoint and center coordinates. Dimensions
for the arc's endpoint (X, Z) may be defined with absolute or incremental dimensions,
depending on the modal G90/G91 condition. All arc center dimensions (I, K) must be
defined using signed incremental dimensions (the distance from the arc's start point to
the arc's center).
If G07 Radius Programming is active, the arc's endpoint (X) and center (I) coordinates
must be programmed as radius values.
If G08 Diameter Programming is active the arc endpoint (X) must be programmed as a
diameter value, but the arc center (I) must be programmed as a radius value.
Example—G03 Arc
The following example part program shows arcs programmed with X, Z, I, and K.
N2 G90 G07 G03 X0.8 Z-0.6 I0 K-0.6 (G90 = Absolute; G07 = Radius)
N7 G90 G08 G03 X1.6 Z-0.6 I0 K-0.6 (G90 = Absolute; G08 = Diameter)
N2 G91 G07 G03 X0.8 Z-0.6 I0 K-0.6 (G91 = Incremental; G07 = Radius)
N7 G91 G08 G02 X1.6 Z-0.6 I0 K-0.6 (G91 = Incremental; G08 = Diameter)
