7.3 Tool table<br />
This table stores information about the tools available indicating the type of tool offset associated<br />
with them, their family, etc.<br />
The end of the chapter describes how to edit the table. Each tool has the following data fields:<br />
Offset number associated with the tool.<br />
Every time a tool is selected, the <strong>CNC</strong> will assume its dimensions as they appear in the tool offset<br />
table for the specified tool offset.<br />
Family code.<br />
It will be used when having an automatic tool changer and it will allow replacing the worn out tool<br />
with another one with similar characteristics.<br />
There are two types of families:<br />
Those for normal tools whose codes are between 0 and 199.<br />
Those for special tools (which occupy more than one magazine pocket), whose numbers are<br />
between 200 and 255.<br />
Every time a new tool is selected, the <strong>CNC</strong> checks whether it is worn out ("real life" greater than<br />
"nominal life"). If that is the case, it will not select it, but it will select another one of the same family,<br />
instead.<br />
If while machining a part, the PLC "asks" the <strong>CNC</strong> to reject the current tool (by activating the logic<br />
input "TREJECT"), the <strong>CNC</strong> will display the message "rejected" in the "STATUS" field and it will<br />
replace it with the next tool of the same family that appear in the tool table. This change will take<br />
place the next time that tool is selected.<br />
Nominal tool life.<br />
It indicates the machining time (in minutes) or the number of operations that that tool is calculated<br />
to last.<br />
Real tool life.<br />
It indicates the machining time (in minutes) or the number of operations already carried out by that<br />
tool.<br />
