Value assignments Information
- It is also possible to specify
the dimensions for the end
point of a rotary axis with
DC(...) irrespective of
G90/G91; also applies to
spindle positioning
Defining a user variable of the
BOOL, CHAR, INT, REAL,
STRING[n] type; define
directly at the beginning of the
program
- Safety clearance for speed
switchover for infeed motion;
note: G340, G341
- G147/G148: Distance of the
cutter edge from the starting
or end point of the contour
G247, G347/G248, G348:
Radius of the tool center
pointpath
- Speed takes effect after the
safety clearance is reached for
the infeed;
note: G340, G341
0, >0 When FRC=0, feedrate F will
act
0, >0 When FRCM=0, feedrate F
will act
- A GoTo operation is
performed to a block marked
by a label; the jump
destination is in the direction
of the program start.
- A GoTo operation is
performed to a block marked
by a label; the jump
destination is in the direction
of the end of the program.
The dimension can be
specified for the end or center
point of a certain axis
irrespective of G90.
