Machining sequence for milling and finishing
Machining sequence for parting
Machining sequence for rechucking
Main machining Submachining Location Description
Finish-milling Contour analysis: Determining the milling contours.
Sequence – Milling operation:
 Linear and circular slots
 Open contours
 Closed contours (pockets), single surfaces and centric
polygons
Sequence – Location:
 Front (also machines Y front)
 Lateral surface (also machines Y surface)
– then the elements are machined according to the sequence
of geometrical definition
– – Finish-machine all elements at all machining locations
– Face Finish-machine all elements on the front face
– Lateral Finish-machine all elements on the lateral surface
Contour, slot, pocket
(*) – Finish selected element at all machining locations
Contour, slot, pocket
(*) Face Finish selected element on the face
Contour, slot, pocket
(*) Lateral Finish selected element on the lateral face
*: Define the milling operation
Main machining Submachining Location Description
Parting All – The workpiece is cut off
Full-surface machining – The workpiece is cut off and rechucked
Main machining Submachining Location Description
Rechucking Full-surface machining – The workpiece is rechucked.
