21.7 Swiveling
Example 6: Setting up a turning machine with B axis
For turning machines with an additional rotary axis B, the tool can be aligned or swiveled on
the X/Z plane. If your machine has a counterspindle, you can, for example, machine with a
tool alternating between the main spindle and counterspindle.
You require the following swivel data sets to use the "Align tool" and "Swivel plane" functions:
● Swivel data set 1 for aligning and swiveling tools on the main spindle and counterspindle
(turning, face Y/C, surface Y/C).
● Swivel data set 2 for machining inclined surfaces when milling on the main spindle (face
B).
● Swivel data set 3 for machining inclined surfaces when milling on the counterspindle (face
B).
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 1.
This is the reason why in the program editor "Swivel tool → align turning or milling tool" is listed
for swivel data set 1.

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.
