Even mixed machine kinematics
(e.g. 1st rotary axis automatic, 2nd rotary axis manual),
and "incomplete" machine kinematics
(e.g. 1st rotary axis rotates around axis X) are allowed.
If machine kinematics are to be implemented with just
one rotary axis, this must always be declared as the
1st rotary axis.
For the swivel angle display, see display messages
CYCLE800 à 62180/62181
Angular range
$TC_CARR30[n] .. $TC_CARR33[n]
A valid angular range must be assigned to each rotary
axis. This must not be the software end position range of
the particular rotary axis.
With modulo axes, enter a traversing range of between
0 and 360 degrees.
Hirth tooth system
$TC_CARR26[n]... $TC_CARR29[n]
• no
The fields below are concealed.
• yes
à Angular offset of Hirth tooth system at beginning
of gearing.
à Angular grid of Hirth tooth system
à Automatic correction yes/no
The tool might exit the angular grid set for the Hirth
tooth system if the swivel head jams. If this happens,
the swiveled frame will need to be recalculated
(TCOABS) with the current angular values (of the
Hirth tooth system). This functionality is calculated by
the Automatic correction (yes) setting in the swivel
cycle.
Swivel data record change (only relevant for ShopMill/ShopTurn)
• no
• automatic
• manual
Tool change (only relevant for ShopMill/ShopTurn)
• automatic
• manual
"Tool change" display for kinematic type T and M only
