Centric predrilling
Centric predrilling – Tool selection
Tool selection
Parameter
Meaning
1st drilling diameter limit
UBD1
1st predrilling step: if
UBD1
<
DB1max
Tool selection:
UBD1
<=
db1
<=
DB1max
2nd drilling diameter limit
UBD2
2nd predrilling step: If
UBD2
<
DB2max
Tool selection:
UBD2
<=
db2
<=
DB2max
For predrilling, a maximum of three drilling steps is used:
1st predrilling step (limit diameter
UBD1
)
2nd predrilling step (limit diameter
UBD2
)
Finish-drilling step
Finish-drilling is performed with: dimin <=
UBD2
Tool selection:
db
=
dimin
Designations in the figures at right:
db1
,
db2
: Drill diameter
DB1max
: Max. inside diameter for 1st drilling step
DB2max
: Max. inside diameter for 2nd drilling step
dimin
: Min. inside diameter
BBG
(drilling limitation elements): Contour elements intersected
by
UBD1
and
UBD2
UBD1
and
UBD2
have no effect when
Centric
predrilling
has been defined as main machining
operation followed by
Finish-drilling
as
submachining operation in the machining sequence

Programming User's Manual
Prerequisite:
UBD1
>
UBD2
UBD2
must permit subsequent inside machining with
