Entering tool data in the table

You can define and store up to 9999 tools and their tool data in a tool
table. Also see the Editing Functions later in this Chapter. In order to
be able to assign various compensation data to a tool (indexing tool
number), insert a line and extend the tool number by a dot and a
number from 1 to 9 (e.g. T 5.2).

You must use tool tables if

you wish to use indexed tools such as stepped drills with more than
one length compensation value

your machine tool has an automatic tool changer

you want to rough-mill the contour with Cycle G122, (see "User's
Manual for Cycle Programming, ROUGH-OUT")

you want to work with Cycles 251 to 254 (see "User's Manual for
Cycle Programming," Cycles 251 to 254)

Tool table: Standard tool data

If you create or manage further tool tables, the file name
has to start with a letter.

You can select either list view or form view for tables via
the "Screen layout" key.
