The tool name (ID), which consists of up to 28 characters of any type, is
used to uniquely identify each tool used. It is displayed within the control-
ler system, both on the user interface as well as on the SOT (Station Op-
erator Terminal).
Any tools which are used must be uniquely named so that they can be
clearly identified. Tools which can replace one another (spare tools) are
listed under a single tool name (ID). An additional tool index number (see
section below) is then used to differentiate such tools.
The extended tool name (ID) allows each operation-specific tool identifi-
cation system to be retained on the controller level.
The storage datum does not appear directly in the tool list since the tool
list only includes the spindles in addition to the tool storage system
(storage = 0). The spindles are indicated by an Sx (x = 1..4) placed in
front of the location number in the tool list.
The location datum defines the tool storage location in the tool storage
system; and, with spindles, it defines the spindle on which the tool is lo-
cated. All tool storage locations as well as all spindles which are present
can be configured with data using the tool list.
CAUTION
After a tool list has been loaded into the controller, it is
important to make certain that the tools actually located in
the magazine match those in the tool list. If a tool maga-
zine is incorrectly loaded, the workpiece and the machine
itself may be damaged.
Within an NC-program, it is possible to access a tool or a location by us-
ing the T word, which is comprised of the initial address letter T and a tool
number (up to 7 digits) or a location number (up to 3 digits). A pro-
grammed tool number causes the tool management system to determine
the current location of the tool based on the tool number contained in the
active tool list.
NOTE
Effective Version 4.14, the data element of the tool num-
ber is contained in the setup list and in the tool list. If
automatic tool checking is set, the tool numbers in the
setup list take precedence and overwrite any assign-
ments which may be present in the tool list.
The tool index number is used:
•
to uniquely identify spare tools (tools which have the same tool name
(ID) and the same T-number )
•
and to specify the order in which spare tool will be used in machining
work.
Spare tools are used based on their tool index number; spare tools which
have a low index number are given preference over tools which have a
higher index number if they are not completely worn or locked.
Spare tools are addressed from the NC-program using the same T-num-
ber.
The controller does not change to a new spare tool until the same T-
number is called again and the previously used tool (i.e. a tool having the
same tool number and name (ID) and the next lower index number) is
worn or locked.
The Correction Type establishes the number of corrections used on a tool
and their orientation (see Fig. 5-5).
