(2) R-specified circular interpolation
Besides the designation of the arc center coordinates using the above-mentioned I, J and K commands,
arc commands can also be issued by designating the arc radius directly.
G02(G03) Xx1 Yy1 Rr1 Ff1 ; (Also possible for additional axes A, B, C, U, V, W )
G02,G03
: Arc rotation direction
Xx1,Yy1
: End point coordinate
Rr1
: Arc radius
Ff1
: Feed rate
G02 or G03 is used to designate the direction of the arc rotation.
The arc plane is designated by G17, G18 or G19.
The arc center is on the bisector which orthogonally intersects the segment connecting the start and end
points, and the point of intersection with the circle, whose radius has been designated with the start
point serving as the center, is the center coordinate of the arc command.
When the sign of the value of R in the command program is positive, the command will be for an arc of
180 or less; when it is negative, it will be for an arc exceeding 180 .

(C) Current position (arc start point)
(E) Arc end point
(a) The axes that can be commanded simultaneously are the two axes for the selected plane.
(b) The feed rate is controlled so that the tool always moves at a speed along the circumference of the
circle.
(Note 1) The arc plane is always based on the G17, G18 or G19 command. If a command is issued with
two addresses which do not match the plane, an alarm will occur.
