Address Significance
ACP Absolute
coordinate;
approach position
in the positive
direction
(for rotary axis,
spindle)
ACN Absolute
coordinate;
approach position
in the negative
direction
(for rotary axis,
spindle)
ANG Angle for the
specification of a
straight line for the
contour definition
AR Aperture angle for
circular
interpolation
CALL Indirect cycle call
CHF Chamfer;
general use
CHR Chamfer;
in the contour
definition
CR Radius for circular
interpolation
CYCLE... Machining cycle

1.1 Fundamentals of programming
Information
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
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
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
Specified in degrees; one
possibility of defining the circle
when using G2/G3
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
Inserts a chamfer of the
specified chamfer length
between two contour blocks
Inserts a chamfer of the
specified leg length between two
contour blocks
One possibility of defining a
circle when using G2/G3
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.
