7.9 Coordinate system rotation, pattern rotation, (G73)
Function G73 may be used to rotate the coordinate system taking as
rotation center the active reference system (part zero) or the
programmed rotation center.
Programming
The coordinate system rotation must be programmed alone in the
block. The programming format is "G73 Q I J", where:
To cancel the coordinate (pattern) rotation, program function G73
alone, with no additional data.
Therefore, function G73 may be programmed as follows:
Q Indicates the rotation angle in degrees.
I, J They define the abscissa and ordinate of the rotation center.
They must be defined in absolute coordinates referred to part
zero.
When programmed, both parameters must be programmed.
If not programmed, the part zero will be assume as the rotation
center.
G73 Q90 G73 Q90 I20 J30
G73 Q I J Rotate "Q" degrees with the center at abscissa "I" and ordinate
"J" referred to part zero.
G73 Q Rotate "Q" degrees with the center at part zero.
G73 Cancellation of coordinate (pattern) rotation.
