21.7 Swiveling
Name of the swivel data set
Figure 21-4
If several swivel data sets are declared in each NC channel, then a name is assigned to each
swivel data set: $TC_CARR34[n]
No name needs to be specified if the swivel-mounted tool holder is not exchangeable (i.e. one
swivel data set per channel).
The name of the swivel data set may only contain characters that are permissible for NC
programming: A...Z, 0...9 and _ !
If several NC channels have been set up, note the settings in MD28085, Chapter "Technology
cycles for swiveling (Page 558)". If a TO unit is assigned to several NC channels, the channel
display in the dialog corresponds to the TO unit.
Offset vectors I1 to I4 $TC_CARR1[n] ... $TC_CARR20[n]
The vectors always contain three components which represent the reference to the machine
axes (X, Y, Z). The positions in the kinematic chain are measured by the machine
manufacturer; they are always relevant with respect to a swivel head/swivel table (swivel data
record).
Offset vectors I1 to I4 refer to the non-swiveled state of the rotary axes (basic setting: machine
kinematics). However, be aware that the traversing range in the swivel planes may be
restricted. If machine kinematics are to be implemented with just one rotary axis, this must
always be declared as the 1st rotary axis.
