5.4 Tool number (T)
The "T" code identifies the tool to be selected. The tools may be in a
magazine managed by the CNC or in a manual magazine (referred
to as ground tools).
The programming format is T<0-4294967294> and it can be
programmed using parameters and arithmetic expressions. In these
cases, by default, the value calculated is rounded up to an integer. If
the result is negative, the CNC will issue the pertinent error message.
Defintion
To load a tool in the spindle, it must be previously defined. To do that,
the CNC offers a table where the user may define the data for each
tool.
On the other hand, when having a magazine managed by the CNC,
one must define the magazine position occupied by each tool. To do
that, the CNC offers a table where the user may define the position
of each tool.
The table data may be defined:
• Manually from the CNC's front panel (as described in the
Operating Manual).
• Via program, using the associated variables (as described in the
relevant chapter of this manual).
Load a tool in the spindle.
The tool required for machining may be selected by program using the
"T<n>" code where <n> is the number of the tool to be loaded in the
spindle.
The "T" code only selects the tool. After selecting a tool, function M06
must be programmed to load it into the spindle. Loading/unloading is
carried out depending on the subroutine associated with the M06 (if
so defined by the machine manufacturer).
