2.13 G53: Move in absolute coordinates
For linear motion to a point expressed in absolute coordinates, program G1 G53 X-
Y- Z- A- B- C- (or use G0 instead of G1), where all the axis words are
optional,except that at least one must be used. The G0 or G1 is optional if it is the
current motion mode. G53 is not modal and must be programmed on each line on
which it is intended to be active. This will produce coordinated linear motion to the
programmed point. If G1 is active, the speed of motion is the current feed rate (or
slower if the machine will not go that fast). If G0 is active, the speed of motion is
the current traverse rate (or slower if the machine will not go that fast).
It is an error if:
* G53 is used without G0 or G1 being active,
* or G53 is used while cutter radius compensation is on.
See Section [sub:Coordinate-Systems] for an overview of coordinate systems.
2.14 G54 to G59.3: Select Coordinate System
G59.3:>
To select coordinate system 1, program G54, and similarly for other coordinate sys-
tems. The system-number-G-code pairs are: (1-G54), (2-G55), (3-G56), (4-G57), (5-
G58), (6-G59), (7-G59.1), (8-G59.2), and (9-G59.3).
It is an error if:
* one of these G-codes is used while cutter radius
compensation is on.
See Section [sub:Coordinate-Systems] for an overview of coordinate systems.
2.15 G61, G61.1, G64: Set Path Control Mode
G64:>
Program G61 to put the machining center into exact path mode, G61.1 for exact
stop mode, or G64 P- for continuous mode with optional tolerance. It is OK to
program for the mode that is already active. See Section [sub:Path-Control-Mode]
for a discussion of these modes.
2.16 G80: Cancel Modal Motion
Program G80 to ensure no axis motion will occur. It is
an error if:
