Machining sequence for drilling
Main machining Submachining Location Description
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
All – All drilling/boring operations at all machining locations
All Centric Centric machining of all drilling/boring operations
All Face All drilling/boring operations on the front face
All Lateral All drilling/boring operations on the lateral surface
