The following tool call is programmed in the NC program:
N10 T=1
The call is processed as follows:
1. Magazine location 1 is considered and the tool identifier determined.
2. The tool management recognizes that this tool is blocked and therefore cannot be used.
3. A tool search for T="drill" is initiated in accordance with the search method set:
"Find the active tool; or else, select the one with the next highest duplo number."
4. The following usable tool is then found:
"Drill", duplo no. 3 (at magazine location 4)
This completes the tool selection process and the tool change is initiated.
Note
If the "Select the first available tool from the group" search method is employed, the
sequence must first be defined within the tool group being loaded. In this case group T10
is loaded, as T15 is blocked.
When the strategy "Take the first tool with "active" status from the group" is applied, T1 is
loaded.
