While the rotation axes are moving, the CNC controls the control points so that the
tool center point moves along an arc with respect to the table (workpiece). The end
of the tool center point comes to the point specified on the programming coordinate
system.
CAUTION
1 Only arc radius R can be specified. (The distance from the start
point to the center of the arc cannot be specified using I, J, and K.)
2 A full circle (the start point and end point are the same) cannot be
specified.
Any command that does not move the tool center point with respect
to the workpiece (one that moves the rotation axes only) must be
executed in G00 or G01 mode.
3 See the CAUTION box for “Position and linear interpolation for tool
center point control (type 2)”.
