Value assignments Information
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
Only specified The call of the machining cycles
values 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.
- 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
