Machining sequence for roughing with hollowing
Main machining Submachining Location Execution
(Roughing) Hollowing Contour analysis: Using the “inward copying angle (EKW),” you
can determine recess areas (undefined recesses). The machining
operation is performed with one or two tools.
Sequence: First outside, then inside machining
Machining parameter: 1 – Global parameters for finished parts
– – Longitudinal machining, transverse machining – outside and inside
Longitudinal Outside Longitudinal machining – outside
Longitudinal Inside Longitudinal machining – inside
Transverse Outside Transverse machining – outside, front and back
Transverse Inside Transverse machining – inside
Transverse Outside/
front Transverse machining – outside/front
Transverse Outside/
back Transverse machining – outside/back
Neutral tool – Longitudinal machining, transverse machining – outside and inside
Neutral tool Outside Longitudinal machining – outside
Neutral tool Inside Longitudinal machining – inside
Neutral tool Outside/
front Transverse machining – outside, front and back
Neutral tool Inside/front Transverse machining – inside
If hollowing precedes recess-turning/contour-recessing in
the machining sequence, recess areas are hollowed –
exception: no suitable tools are available.
