Feed rate reduction:
Indexable insert drill and twist drill with 180° drilling angle
A feed rate reduction is only effective if the parameter Tap/
Drill. lth A has been defined
Other drills
Beginning of hole: Feed rate reduction as programmed in V
End of hole: Reduction as of hole end point—length of first
cut—safety clearance
Length of first cut = tool tip
Set-up clearance
Further information: "Safety clearance", Page 310
Cycle run:
1 Approach behavior:
Hole without contour definition: Tool is located at the starting
point (safety distance from the bore hole)
Hole with contour definition: Tool moves at rapid traverse to
the starting point
RB not programmed: Moves up to the safety clearance
RB programmed: Moves to the position RB and then to
the safety clearance
2
Spot drilling. Feed rate reduction depending on V
3 Drill hole at feed rate.
4
Through drilling. Feed rate reduction depending on V
5
Retraction at rapid traverse or feed rate, depending on D
6 Retraction position:
RB not programmed: Retraction to the starting point
RB programmed: Retraction to the position RB
