Note
This function is not available with version T/M value.
Indexing axes in machine tools
In certain applications, the axis is only required to approach specific grid points (e.g. location
numbers). It is necessary to approach the defined grid points, the indexing positions, both in
AUTOMATIC and set-up mode.
The relevant axes are called "indexing axes". The positions defined on the indexing axes are
known as "coded positions" or "indexing positions".
Applications
Indexing axes are used predominantly in connection with specific types of tool magazines
such as tool turrets, tool chain magazines or tool cartridge magazines. The coded positions
refer to the individual locations of the tools in the magazines. During a tool change, the
magazine is positioned at the location containing the tool to be loaded.
Display indexing
The following data can be queried via system variables:
● The number of the current indexing position:
– When the "exact stop fine" window of the indexing position is reached
– When half the distance to the next indexing position is crossed
● The programmed indexing position
