2.2.7 Tool management or "Flat D numbers"
Tool management
NCK active tool management works on the basis of the following assumptions:
1. Tools are managed in magazines.
2. Cutting edges are monitored; limits reached cause the tool to be disabled.
3. Idea behind replacement tools: Tools are programmed for selection only the on the basis
of their identifier. NCK then selects the concrete tool according to the strategy.
This means that it only makes sense to employ tool management when specific tools have
been defined and these are to be utilized by the NCK.
Flat D number
Flat D number means that tool management is carried out outside the NCK and there is no
reference made to T numbers.
No mixture of tool management and flat D no.
It does not make sense to mix or distribute the tool management functions over the NCK and
PLC, since the main reason for tool management on the NCK is to save time.
This only works if the tasks that are timecritical are carried out on the NCK. This is not the
case for "Flat D number", however.
Note
Activation of both of the functions "Flat D number structure" and "Tool management" is
monitored. If both are activated at the same time, "Tool management" takes priority.
