T1: Indexing axes
16.6 Starting up indexing axes
Example of indexing axis as rotary axis
Tool turret with 8 locations. The tool turret is defined as a continuously rotating rotary axis.
The distances between the 8 turret locations are constant. The first turret location is located
at position 0°:
Figure 16-3
The indexing positions for the tool turret are entered in indexing position table 1.
