7.3.4 Tool monitoring.
The PLC marks related to tool monitoring are the following. There is one group of marks for
each channel.
The following table shows the mnemonics for each mark (M) in each channel or magazine.
The PLC marks related to tool monitoring are:
CUTTINGON
When a tool is assigned a maximum life span (monitoring), the CNC checks this mark in order
to know whether the tool is machining (=1) or not (=0).
It is usually considered to be machining when the following conditions are met:
• The spindle is turning (M3 or M4) or when the tool is threadcutting and the 0% of feedrate
is not selected.
• The automatic operating mode is selected, there is a block in execution and the G00
function is not active.
• The execution is not interrupted.
TREJECT
If the PLC sets this mark high (=1), the CNC interprets that the tool must be rejected.
TWORNOUT
The CNC sets this mark high (=1) to "tell" the PLC that the tool has been rejected because
it is worn out (real life > maximum life span).
