Machining sequence for contour recessing
Machining sequence for recessing
Main machining Submachining Location Execution
Contour recessing Contour analysis: Recess areas (recesses) are determined and
machined according to the “inward copying angle (EKW).”
Sequence: First outside, then inside machining
Machining parameter: 1 Global parameters for finished parts
– – Radial/axial machining – outside and inside
Shaft machining: Axial machining on the outside is performed on
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
Contour-parallel Inside/front Axial machining – inside
 If contour recessing precedes hollowing in the
machining sequence, recess areas are machined by
contour recessing – exception: no suitable tools are
available.
 Recess turning – contour turning are used alternatively.
Main machining Submachining Location Execution
Recessing Contour analysis: Determining the “Recess” form elements:
 Type S (guarding ring – recess type S)
 Type D (sealing ring – recess type D)
 Type A (recess general)
 Type FD (relief turn F) – FD is only machined using “Recessing”
if the “inward copying angle (EKW) <= mtw.”
Sequence: First outside, then inside machining
Machining parameter (with type FD): 1 Global parameters for
finished parts

Type S, D, A, FD (*) Outside Radial machining – outside
Type S, D, A, FD (*) Inside Radial machining – inside
Type A, FD (*) Outside/
front
Axial machining – outside
Type A, FD (*) Inside/front Axial machining – inside
*: Define the recess type
