Selection of the shortest life tool
with the tool type number
This is the example of the selection procedure of the tool with tool type
number commanded by T code.
N10 T11111111 ;
(1) The shortest life tool is searched from the tool which tool type number
is 11111111. Because the shortest life tool is tool management data
number No.1, CNC searches the magazine number and the pot number
where this tool is stored in.
The following tools are excluded from the search.
• Tool not allocated in the magazine.
• Tool life state is 0 (life is not managed). (notice:1)
• Tool life state is 3 (life is over).
• Tool life state is 4 (tool is damaged).
• Tool which tool information RGS = 0.
• Tool which data is edited on the tool management data screen.
• Tool which life counter larger than the maximum of its tool life.
When there is two or more tools with the same life value, tool is
selected by the following priority.
high spindle position
wait position
low magazine position
(notice:1)
If the parameter SWC (No.13203#6) is set to 1, the tool which the
customizing data which specified by the parameter No.13260 is the
smallest instead of the shortest life tool is searched in the i series modle
B.
(notice:2)
The tool which the tool information SEN (bit 4) is set to 1 is included
in search target, even if the tool life state is "tool is not managed(0)". In
this case, the left life is not checked and the magazine and pot number
of the first find tool is result.
(2) The tool of tool management data number No.1 is stored in magazine
number = 1 and pot number = 30. So, binary value 0001 is output to
PMC address <F0026-F0027>, and the binary value 0030 is output to
PMC address <F0028-F0029>.
(3) The searched tool is moved to the wait position on the machine.
