4.10 Extended stock removal cycle – CYCLE950 (SW 5.3 and higher)
Programming example 3
The same part as in sample program 1 should now be
machined in two steps.
In the first machining step (N45), roughing is carried out
using a tool with tool point position 9 and a large radius
with deep infeed depth and no blank specified. The
result to be generated is an updated blank with the
name blank3.MPF.
The type of machining for this step is:
only roughing,
longitudinal,
outside,
with rounding,
relief cuts are not be machined.
In the second machining step (N70), the residual
material on this blank is machined with a different tool
and then finished.
The type of machining for this step is:
complete machining (roughing and finishing)
longitudinal,
outside,
with rounding (so that there are no
residual corners),
relief cuts are to be machined.
