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.

directly(for rotary
axis, spindle)
- 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

Position spindle
DEF Definition instruction Defining a local user variable of
the type
BOOL, CHAR, INT, REAL,
