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.
Definition
To select a tool, 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).
Select a tool
The tool required for machining may be selected by program using the "T<n>" code where
<n> is the tool number.
• On a lathe, the "T" code selects the tool in the tool holder.
• On a milling machine, 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).
