Machining sequence for drilling
Main machining Submachining Location Execution
Drilling Contour analysis: Determining the “Hole” form elements.
Sequence – Drilling operations/drilling combinations:
„ Centering / Centering and countersinking
„ Drilling
„ Countersinking / Drilling and countersinking
„ Reaming / Drilling with reaming
„ Tapping / Drilling with thread
Sequence – Location:
„ Centric
„ Front (also machines Y front)
„ Lateral surface (also machines Y surface)
– then the elements are machined according to the sequence of
geometrical definition
– – Machining all bore holes on all machining locations
Centering, drilling,
countersinking,
reaming, tapping
(*) – Execution of the selected drilling operation on all machining
locations
Centering, drilling,
countersinking,
reaming, tapping
(*) Location Machining a bore hole on the selected machining location
*: Define the drilling cycle
Drilling combinations:
„ Define the drilling combinations as machining attributes
(see “Machining attributes – Drilling combinations” on
page 475).
„ Select the appropriate drilling operation as
submachining operation (see above).
