14.11 Coordinate Rotation by Parameter

If a deviation occurs between the workpiece alignment line and machine coordinate system's coordinate axis when the

workpiece is mounted, the machine can be controlled by rotating the machining program coordinates according to the

workpiece alignment line deviation. The coordinate rotation amount and the center of the rotation can be set with the

parameters. The parameters can also be set with the G10 command.

In this manual, the coordinate system after the rotation by the parameter coordinate rotation is referred to as "rotation

coordinate system".

(a) Center of rotation

 As for the coordinate rotation center position, designate the position on the machine coordinate system.

 All workpiece coordinate systems from G54 to G59 and G54.1 rotate with the rotation command. The machine coordinate

system does not rotate.

 When the parameter is set, the setting value will be valid at the following timing:

Automatic oper-

After the parameter is set, the setting value will be valid from the next block.

Manual opera-

After the parameter is set, the setting value will be valid if the PLC signal (Coordinate rotation by param-

eter: Manual feed coordinate system) is ON.

For the details on the operations during the automatic operation and the coordinate rotation functions, refer to the

programming manual.
