Main machining Submachining Location Execution
Recess turning Contour analysis:
■ Without previous rough-machining: The complete
contour, including recess areas (undefined recesses), is
machined.
■ With previous rough-machining: Recess areas
(undefined recesses) are determined from the ”inward
copying angle EKW” and machined.
Sequence: External machining precedes internal
machining.
Machining parameters: Global finished-part parameters
(1)
– – Radial/axial machining – outside and inside
Contour-parallel Outside Radial machining – outside
Contour-parallel Inside Radial machining – inside
Contour-parallel Outside/front Axial machining – outside
Contour-parallel Inside/front Axial machining – inside
■ If recess turning precedes hollowing in the
machining sequence, recess areas are
machined by recess turning. – exception: no
suitable tools are available.
■ Recess turning – contour turning are used
alternatively.
Contour recessing (contour cutting) Contour analysis: Recess areas (recesses) are
determined from the ”inward copying angle EKW” and
machined.
Sequence: External machining precedes internal
machining.
Machining parameters: Global finished-part parameters
(1)
– – Radial/axial machining – outside and inside
Shaft machining: Axial machining on the outside is
executed on the front and back.
Contour-parallel Outside Radial machining – outside
Shaft machining: front and back
Contour-parallel Inside Radial machining – inside
Contour-parallel Outside/front Axial machining – outside
