The tool name, which consists of up to 28 characters of any type, is used
to uniquely identify each tool used. It is displayed within the controller
system, both on the user interface as well as on the SOT (Station Opera-
tor Terminal).
Any tools which are used must be uniquely named so that they can be
clearly identified. Tools which can replace on another (spare tools) are
listed under a single tool name. An additional tool index number is then
used to differentiate them.
The extended tool name allows each operation-specific tool identification
system to be retained on the controller level.
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 and name con-
tained in the setup list and based on the tool name and location number
contained in the active tool list. A tool can be accessed from the NC-pro-
gram based on the correlation between the tool number (as used in the
NC-program) and the tool (operation-specific tool ID) that is assigned in
the setup list.
The Correction Type establishes the number of corrections used on a tool
and their orientations (see also Fig. 5-3).
Correction Type 1
(Drilling Tool)
Correction Type 2
(Milling Tool)
Correction Type 3
(Turning Tool)
Correction Type 4
(Angle Attachment
Tool)
An Correction Type 1 tool
has only 1 length correc-
tion (L3), and this correc-
tion is always perpen-
dicular to the given ma-
chining plane.
An Correction Type 2 tool
has—in addition to the
length correction (L3),
which is always perpen-
dicular to the machining
plane—a radius correction
(R), which lies within the
machining plane.
This type of tool has 2
length corrections (L1, L2)
and a radius correction
(R), which lies within the
machining plane.
Tools of this type have a
length correction (L1, L2,
L3) in all three main axes
(X, Y, Z) and a radius cor-
rection (R) in the current
machining plane. The
length L3 Is always per-
pendicular to the active
machining plane; while
lengths L1 and L2 always
form the active machining
plane.
The correction type of the corresponding tool in the storage must corre-
spond to the type specified in the setup list so that it can be used for the
intended machining operation.
If the letter N is entered as the correction type, the user interface will dis-
play the data for L1, L2, L3 and R in the following edge data correspond-
ing to the settings in the system parameters. When the tool check is per-
formed, only those geometry limits which are required for the Correction
Type are taken from the setup list to check tool geometry.
