X_ Y_: Rotation center coordinates
Specify the 2 axes corresponding to the selected plane in X, Y, and Z in absolute position
G17 specifies X_ Y_, G18 specifies Z_ X_, G19 specifies Y_ Z_
R : Rotation angle, counterclockwise is +
(Note: This command needs to select the command plane in advance through G17~G19)
(2)Coordinate rotation cancelled
G69; Coordinate rotation cancelled
Detailed instructions:
(1)The rotation center coordinates (x1, y1) are always specified in absolute values. It is not treated as an
incremental value even if it is specified with an incremental address.
(2) If the G68 command rotation center coordinate (x1, y1) is omitted, the position of the G68 command
will become the center of rotation.
(3) Rotate the angle specified by the rotation angle r1 counterclockwise.
(4) The setting range of the rotation angle r1 is -360.000 to 360.000. When a command of a degree
exceeding 360 degrees is issued, the command will be the remainder after being divided by 360 degrees.
(5) The rotation angle r1 is modal data and does not change until the new angle is specified next time.
Therefore, the command of the rotation angle r1 can be omitted. If the rotation angle is omitted when the G68
command is issued for the first time, r1 will be regarded as "0".
(6) The program coordinate rotation is a function on the local coordinate system. Therefore, the
relationship between the rotated coordinate system, the workpiece coordinate system, and the basic machine
coordinate is as shown in the figure below.

(7)The coordinate rotation command in the coordinate rotation is treated as a change in the center coordinate
