ACP Absolute
coordinate;
approach position
in the positive
direction
(for rotary axis,
spindle)
- It is also possible to specify the
dimensions for the end point of a
rotary axis with ACP(...)
irrespective of G90/G91; also
applies to spindle positioning
N10 A=ACP(45.3)
;approach absolute
position of the A axis in
the positive direction
N20 SPOS=ACP(33.1)
;position spindle
ACN Absolute
coordinate;
approach position
in the negative
direction
(for rotary axis,
spindle)
- It is also possible to specify the
dimensions for the end point of a
rotary axis with ACN(...)
irrespective of G90/G91; also
applies to spindle positioning

ANG Angle for the
specification of a
straight line for the
contour definition
±0.00001 ...
359.99999
Specified in degrees;
one possibility of specifying a
straight line when using G0 or
G1 if only one end-point
coordinate of the plane is known
or
if the complete end point is
known with contour ranging over
several blocks
N10 G1 X... Z....
N11 X... ANG=...
or contour over several
blocks:
N10 G1 X... Z...
N11 ANG=...
N12 X... Z... ANG=...
AR Aperture angle for
circular
interpolation
0.00001 ... 359.99999 Specified in degrees; one
possibility of defining the circle
when using G2/G3
See G2, G3
CALL Indirect cycle call - Special form of the cycle call; no
parameter transfer; the name of
the cycle is stored in a variable;
only intended for cycle-internal
use
N10 CALL VARNAME ;
variable name
CHF Chamfer;
general use
0.001 ... 99 999.999 Inserts a chamfer of the
specified chamfer length
between two contour blocks
N10 X... Z.... CHF=...
N11 X... Z...
CHR Chamfer;
in the contour
definition
0.001 ... 99 999.999 Inserts a chamfer of the
specified leg length between two
contour blocks
N10 X... Z.... CHR=...
N11 X... Z...
CR Radius for circular
interpolation
0.010 ... 99 999.999
Negative sign - for
selecting the circle:
greater than semicircle
One possibility of defining a
circle when using G2/G3
See G2, G3
CYCLE... Machining cycle Only specified values The call of the machining cycles
requires a separate block; the
appropriate transfer parameters
must be loaded with values.
Special cycle calls are also
possible with an additional
MCALL or CALL.
