4.10 Extended stock removal cycle – CYCLE950 (SW 5.3 and higher)
Function
With the extended stock removal cycle CYCLE950 you
can machine a contour programmed with paraxial or
parallel-contour stock removal. Any blank can be
defined and is considered during stock removal. The
finished part contour must be continuous and may
contain any number of relief cut elements. You can
specify a blank as a contour or by means of axial
values.
Contours can be machined in the longitudinal and
facing directions with this cycle. You can freely select a
technology (roughing, finishing, complete machining,
machining and infeed directions). It is possible to
update a blank.
For roughing, the programmed infeed depth is observed
precisely; the last two roughing steps are divided
equally. Roughing is performed to the programmed final
machining allowance.
Finishing is performed in the same direction as
roughing.
The tool radius compensation is automatically selected
and deselected by the cycle.
