Value assignments Information
- The dimension can be specified
for the end or center point of a
certain axis, irrespective of
G91.
1 ... 200, integer Acceleration override for an
axis or spindle; specified as a
percentage
- 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
±0.00001 ... Specified in degrees;
359.99999 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
0.00001 ... Specified in degrees; one
359.99999 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
0.001 ... 99 Inserts a chamfer of the
999.999 specified chamfer length
between two contour blocks
0.001 ... 99 Inserts a chamfer of the
999.999 specified leg length between
two contour blocks
0.010 ... 99 One possibility of defining a
999.999 circle when using G2/G3
Negative sign - for
selecting the circle:
greater than
semicircle
