value of “R > 0”.
•
For the circular arc with the central angle of 180 deg. or larger, use an R
value of “R < 0”.

(e) Feedrate
In the circular interpolation mode, the feedrate can be specified in the same manner as in
the linear interpolation mode. Refer to 2.1.2 “Linear Interpolation (G01)”.
(2) Supplements to Circular Interpolation
• A circular arc extending to multiple quadrants can be defined by the commands in a
single block. It is also possible to specify a full circle.
