3.5 Circular Interpolation (G02/G03)
These commands will move a tool along a circular arc.
Format: Arc in the XpYp plane
Arc in the ZpXp plane
Arc in the YpZp plane
Code
Description
G17
Specification of arc on XpYp plane
G18
Specification of arc on ZpXp plane(Default)
G19
Specification of arc on YpZp plane
G02
Circular Interpolation Clockwise direction (CW)
G03
Circular Interpolation Counterclockwise direction (CCW)
X/Z/Y Position of end point in workpiece coordinate
U/W/V Distance from start point to end point
I
X axis distance from start point to center of an arc with sign(radius value)
K
Z axis distance from start point to center of an arc with sign(radius value)
J
Y axis distance from start point to center of an arc with sign(radius value)
R
Arc radius with sign (always with radius value)
F
Feedrate along the arc
Direction of circular interpolation:
“Clockwise”(G02) and “Counter clockwise”(G03) on the
XpYp plane(ZpXp plane or YpZp plane) are defined when the XpYp plane is viewed in the positive
to negative direction of the Zp axis (Yp axis or Xp axis respectively) in the Cartesian coordinate
system, See the figure below.

Distance moved on an arc:
The end point of an arc is specified by address Xp , Yp or Zp,
