Finishing – Machining analysis
Machining analysis
Parameter Meaning
Minimum finishing transverse
length
FMPL
TURN PLUS checks the front-
most element of the outside
contour to be finished.
The following applies:
Without inside contour:
Always with additional
transverse cut
With inside contour –
FMPL
>=
l1
: Without additional
transverse cut
With inside contour –
FMPL < l1 : With additional
transverse cut
Maximum finishing cut depth
FMST
FMST
defines the permissible
infeed depth for non-machined
undercuts. The finishing cycle
(
G890 ) uses this parameter to
determine whether undercuts
(
form E, F, G
) will be machined
with a contour-finishing opera-
tion.
The following applies:
FMST > ft : With undercut
machining ( ft : undercut
depth)
FMST <= ft : Without
undercut machining
Number of revolutions for
chamfer or rounding
FMUR
The feed rate is reduced such
that at least
FMUR revolutions
can be executed (evaluation:
finishing cycle
G890
).
The following applies to FMPL:
The additional transverse cut is executed from the
outside toward the inside
The
Transverse angle variation PWA has no effect
on the analysis of the transverse elements
