(Set Work Coordinate Systems Shift Value).
G53 Non-Modal Machine Coordinate Selection (Group 00)
This code temporarily cancels work coordinate offsets and uses the machine
coordinate system. In the machine coordinate system, the zero point for each
axis is the position where the machine goes when a Zero Return is performed.
G53 will revert to this system for the block it is commanded in.
G54-59 Select Work Coordinate System #1 - #6 (Group 12)
These codes select one of the six user coordinate systems. All future referenc
-
es to axes positions will be interpreted using the new (G54 G59) coordinate
system.
G60 Uni-Directional Positioning (Group 00)
This G code is used to provide positioning only from the positive direction. It is
provided only for compatibility with older systems. It is non-modal, so does not
affect the blocks that follow it. Also see Setting 35.
G61 Exact Stop Mode (Group 15)
The G61 code is used to specify an exact stop. It is modal; therefore, it affects
the blocks that follow it. The machine axes will come to an exact stop at the
end of each commanded move.
G64 G61 Cancel (Group 15)
The G64 code is used to cancel exact stop (G61).
G68 Rotation (Group 16)
(This G-code is optional and requires Rotation and Scaling.)
G17, G18, G19
optional plane of rotation, default is current
A
optional center of rotation for the first axis of the selected plane
B
optional center of rotation for the second axis of the selected plane
R
optional angle of rotation specified in degrees
Three-place decimal -360.000 to 360.000.
A G17, 18 or 19 must be used before G68 to establish the axis plane being
rotated. For example: G17 G68 Annn Bnnn Rnnn;
A and B correspond to the axes of the current plane; for the G17 example A is
the X-axis and B is the Y-axis.
A center of rotation is always used by the control to determine the positional
values passed to the control after rotation. If any axis center of rotation is not
specified, the current location is used as the center of rotation.
When rotation (G68) is commanded, all X, Y, Z, I, J, and K values are rotated
through a specified angle R using a center of rotation.
G68 will affect all appropriate positional values in the blocks following the G68
command. Values in the line containing G68 are not rotated. Only the values in
the plane of rotation are rotated, therefore, if G17 is the current plane of rota
