Overview of machining sequences
Machining sequence for centric predrilling
Machining sequence for roughing without hollowing
Special machining has no significance for the AWG.
Main machining Submachining Location Description
Centric predrilling Contour analysis: Determining the drilling steps
Machining parameter: 3 – Centric predrilling
– – Predrilling of 1st step
Predrilling of 2nd step
Finish-drilling
Predrilling – Predrilling of 1st step
Predrilling of 2nd step
Finish-drilling – Finish-drilling
Main machining Submachining Location Execution
Roughing (without hollowing) Contour analysis: Dividing the contour into areas for longitudinal/
transverse outside machining and longitudinal/transverse inside
machining according to the transverse/longitudinal ratio.
Sequence: First outside, then inside machining
Machining parameter: 4 – Roughing
– – Transverse machining, longitudinal machining – outside and inside
Longitudinal – Longitudinal machining – outside and inside
Longitudinal Outside Longitudinal machining – outside
Longitudinal Inside Longitudinal machining – inside
Transverse – Transverse machining
Contour-parallel – Contour-parallel machining – outside and inside
Contour-parallel Outside Contour-parallel machining – outside
Contour-parallel Inside Contour-parallel machining – inside
