Full-surface machining
You describe the geometry of the blank and finished part, and TURN
PLUS generates the working plan for the complete workpiece.
Preconditions for full-surface machining:
„ In the program head the spindle and the slide for the second setup
are defined (“2nd setup ..” input boxes).
„ In the machining sequence the main machining operation
“Rechucking”“ or “Parting” is entered after the machining of the
front face.
Depending on the main machining and submachining entries defined
in the machining sequence, TURN PLUS activates one of the following
expert programs (machining parameter 21):
„ “Rechucking – Full-surface machining” entry: TURN PLUS activates
the expert program entered in SP-UMKOMPL. The opposing spindle
takes over the workpiece.
„ “Parting – Full-surface machining” entry: TURN PLUS activates the
expert program entered in SP-UMKOMPLA. The workpiece is cut
off and transferred to the opposing spindle (machining of bars).
To influence rear-face machining in the machining sequence: see
“Machining sequence – Fundamentals” on page 535
The NC program generated includes front and back machining
(including the drilling, milling and inside machining), calling the expert
program, and the clamping information of both setups.
