Conditions
The motion differs if:
l Cutter radius compensation is active
l G53 is programmed on the same line
Troubleshooting
It's an error if:
l All axis words are omitted
The axis words are optional, except that at least one
must be used.
l G10, G28, G30 or G92 appear in the same block
9.2.3 Linear Motion at Feed Rate (G01)
For linear motion at feed rate (for cutting or not), program:
G01 X~ Y~ Z~ A~ F~
l X~ is the X-axis coordinate
l Y~ is the Y-axis coordinate
l Z~ is the Z-axis coordinate
l A~ is the A-axis coordinate
l F~ is the feed rate
This produces coordinated linear motion to the destination
point at the current feed rate (or slower, if the machine won’t
go that fast). The G01 is optional if the current motion mode is
G01.

9.2.4 Arc at Feed Rate (G02 and G03)
A circular or helical arc is specified using either G02 (clockwise
arc) or G03 (counterclockwise arc). The axis of the circle or
helix must be parallel to the X-, Y- or Z-axis of the machine
coordinate system. The axis (or equivalently, the plane
perpendicular to the axis) is selected with G17 (Z-axis, XY-
plane), G18 (Y-axis, XZ-plane) or G19 (X-axis, YZ-plane). If the
arc is circular, it lies in a plane parallel to the selected plane.
If a line of code makes an arc and includes rotational axis
motion, the rotational axes turn at a constant rate so that the
rotational motion starts and finishes when the XYZ motion
starts and finishes. This is rare.
The motion differs if cutter radius compensation is active.
Two formats are allowed for specifying an arc: the center
format and the radius format. In both formats, the G02 or G03
is optional if it's the current motion mode.
Radius Format Arc
For a clockwise arc in radius format, program: G02 X~ Y~
Z~ A~ R~
For a counterclockwise arc in radius format, program: G03 X~
Y~ Z~ A~ R~
l X~ is the X-axis coordinate
l Y~ is the Y-axis coordinate
l Z~ is the Z-axis coordinate
l A~ is the A-axis coordinate
l R~ is the radius of the arc
In radius format, the coordinates of the end point of the arc in
the selected plane are specified along with the radius of the
arc. A positive radius indicates that the arc turns through 180
degrees or less, while a negative radius indicates a turn of 180
degrees to 359.999 degrees.
If the arc is helical, the value of the end point of the arc on the
coordinate axis parallel to the axis of the helix is also specified.
We don't recommend programming radius format arcs that
are:
l Nearly full circles
l Semicircles
l Nearly semicircles
A small change in the location of the end point produces a
much larger change in the location of the center of the circle
(and the middle of the arc). The magnification effect is large
enough that rounding error in a number can produce out-of-
tolerance cuts.
