Cancellation and suspension of origins and lengths (G53 G54 G45)
These functions must be used by expert programmers.
To
cancel an origin
it is necessary to program the base origin, for example:
OZ0 OX0
To
cancel
the
tool length corrections
it is necessary to program a null length:
LX0 LZ0
To
suspend
the corrections introduced by supplementary origins and tool length it is possible to program the
G53 function. By programming the G53 function, all roto-translations, mirroring and scale factors are
suspended, in order to reference all movements to the base origin. After programming the G53 function, all
movements are related to the base origin (origin “0”)
The
restoring
of corrections due to supplementary origins and tool length happens by programming the
G54
function. After programming the G54 function, the situation of origins, lengths, roto-translations, mirroring and
scale factors existing before the G53 programming is restored.
To
suspend
only the correction due to the tool length it is possible to use the
G45
function. After programming
of the G45 function, all movements of the tool axis don’t take into account the tool length. The correction can
be
restored
by programming the
G43
or
G44
function.
