22.6 Swiveling
Example 7: Configuring a milling machine with B axis for turning.
You can configure a milling machine with a B axis (rotation around Y) so that turning is
possible.
The following example refers to a milling machine with a rotary axis around Y (B), a rotary
axis around Z (C) and a main spindle (SP) in the tool direction Z (G17).
You require the following swivel data sets to use the "Align tool" and "Swivel plane"
functions:
● Swivel data set 1 for "Swiveling in the plane" when milling.
Mixed kinematics: Rotary axis 1: B-axis, rotary axis 2: C axis
● Swivel data set 2 for the "Swivel tool - align tool" when turning
Swivel head: Rotary axis 1: B-axis, rotary axis 2: Spindle SP
When milling, the SP spindle is the master spindle. Rotary axis C is declared as the master
spindle in rotational operation, e.g. SETMS(2).
When commissioning the "B-axis kinematics turning technology" in parameter
$TC_CARR37[n], the TEN THOUSANDS position must be set to 2 or 3 in swivel data set 2.
This is the reason why in the program editor "Swivel tool → align turning or milling tool" is
listed for swivel data set 2.

Description of Functions, Basic Functions; Tool Offset (W1), Parameter CUTMOD:
● The CUTMOD NC function is activated when data set 2 is called in the NC program
(CYCLE800 align turning tool). This means that the cutting edge position or the tool
reference point is updated corresponding to the tool orientation:
● When calling a swivel data set for rotational operation in the NC program (CYCLE800
align tool), the CUTMOD NC function is activated. The cutting edge position, tool angle,
cut direction and tool reference point are thus calculated in accordance with the current
tool orientation following the "Align tool" function.
22.6.5

Manufacturer cycle CUST_800.SPF

Function
During swiveling, all axis positions are approached using the CUST_800.SPF cycle. The call
is exclusively made from the swivel cycle CYCLE800 or from the cycles
E_TCARR (ShopMill) or F_TCARR (ShopTurn).
