Transfer position in Z (LD):
■
0: Transfer position in machine dimension 1
■
1..6: Transfer position in machine dimension 1..6
■
≠ 0..6: Transfer position – Calculation of the proposed value:
see sketch
Working position in Z (LE): Proposed value: Zero-point offset, such as
from machine parameter 1164 for Z axis $1
Finished part length (LF): From the workpiece description
Distance from stop surface (LH): Distance between reference point of
chuck and stop surface of the clamping jaw, calculated from
the second setup
Minimum traverse (I):
■
Without moving to fixed stop: Safety clearance on the
workpiece to be transferred – proposed value: From ”safety
clearance on blank” (machining parameter 2)
■
With traverse to a fixed stop: See machine manual
Maximum traverse (J):
■
No input: Without traverse to fixed stop
■
With input: With traverse to fixed stop – meaning of the
parameters I and J: See machine manual
1, if 2 workpieces (U): No meaning

Process of parting and workpiece transfer:
Select the vertical element for the parting – TURN
PLUS opens the dialog box of the expert program
Check/edit the ”parting” parameter
The parting operation starts afer OK is pressed
Define the chucking data and position for the secon
setup
Check/edit the ”workpiece transfer” parameter
The workpiece transfer starts afer OK is pressed
TURN PLUS entered the calculated parameters als
proposed values. Check, edit or enter the values.
The meaning of the transfer program
depends on the name of the expert
program.

”Parting” (see sketch)
Spindle speed limitation (LA) for the parting process
Maximum diameter of workpiece blank (LB):
Proposed value: from the tool description
Reduced feed rate (K): for the parting operation
■
0: No feed rate reduction
■
>0: (Reduced) feed rate
Starting point in X (O): For the parting operation –
proposed value: from the workpiece
description
Start point in Z (P): For the parting operation –
proposed value: Vertical element from the
”selection”
”Workpiece transfer” (see also ”
6.11 Prepare –
Rechuck”)
Speed or anglular synchronism (LC):
■
0: Angular synchronism without angular
offset
■
>0: Angular synchronism with preset
angular offset
■
<0: Spindle speed synchronism
