Parting (Cutting-off)
The workpiece is parted with the expert program that is entered in
machining parameter 21 – ”UP 100098.” Expert programs are
provided by the machine tool builder. That is why there may be
deviations in the parameters described below. Use the expert pro-
gram or the machine manual to inform yourself of the meaning of the
parameters and the process of the expert program.
TURN PLUS determines the parameters as far as possible and enters
them as default values. Check, edit or enter the values.
Parameters
Bar diameter (LA):
Starting point in Z (LB): TURN PLUS uses the position that you defined
when selecting the machining range.
Chamfer/rounding (LC):
■
< 0: Width of chamfer
■
> 0: Radius of rounding
Feed-rate reduction from X (LD): Feed rate is reduced for the last path
(the reduced feed rate is defined in the expert program).
Diameter of finished part (LE): for determining the position of the
chamfer/rounding
Inside diameter (LF): The expert program moves past this position in
order to ensure a proper parting operation.
■
= 0: for a solid bar
■
> 0: for a tube
Safety clearance (LH): to starting position X
Cutting width (I): is usually not evaluated
Select the machining range:
Vertical element, at which part is to be
parted – and the chamfer/rounding.

”Parting” parameters
Parting and tool transfer
TURN PLUS activates an expert program (from machining
parameter 21) for parting and for workpiece transfer. Which expert
program is used depends on the entry ”1st setup of spindle .. – 2nd
setup of spindle ..” in the program header:
■
Same spindle (manual rechucking): Enter ”UP-ABHAND”
■
Different spindles (transfer of workpiece to the opposing spindle):
Enter ”UP-UMKOMPLA”
Expert programs are provided by the machine tool builder. That is why
there may be deviations in the parameters described below. Use the
expert program or the machine manual to inform yourself of the
meaning of the parameters and the process of the expert program.
