ROTATION WITH CUTTER COMPENSATION
Cutter compensation should be turned on after the rotation and scaling commands are issued. Compensation
should also be turned off prior to turning rotation or scaling off.
G69 Cancel G68 Rotation (This G-code is optional and requires Rotation and Scaling) Group 16
G code 69 cancels any rotation specified previously.
WORK C OORDINATE S YSTEM S ELECTION (G52, G53, G54-59)
Note: The G52 command works differently depending on the value of Setting 33. This
setting selects the FANUC, HAAS, or YASNAC style of coordinates, which are
listed below:
G52 Set Work Coordinate System G52 YASNAC Group 12
This code selects the G52 work coordinate system. The G52 works the same as G54 etc., except that the
G52 system will be set by a G92 code as well as from the offsets display.
YASNAC compatible.
G52 Set Local Coordinate System FANUC Group 00
This code sets the origin of the local (child) coordinate system to the command location, relative to the current
work system origin. G52 is a non-modal, no motion code. The G52 coordinate system will stay in effect for all
work systems until it is canceled. The G52 is canceled when RESET is pressed and at the end of a program.
It is also canceled during a program by M30, G52 X0 Y0 Z0, or by a G92 command.
G52 Set Local Coordinate System HAAS Group 00
This code acts the same as in the Fanuc control except that G52 is not cleared at power-up, RESET, or when
an M30 is performed.
G53 Non-Modal Machine Coordinate Selection Group 00
This code temporarily cancels work coordinates offset and uses the machine coordinate system. It is non-
modal; so the next block will revert to whatever conditions were previously selected.
G54-59 Select Coordinate System #1 - #6 Group 12
These codes select one of the six user coordinate systems stored within the offsets memory. All subsequent
references to axesîš’ positions will be interpreted in the new coordinate system. Work coordinate system offsets
are entered from the Offsets display page.
