Tool life management and tool exchange
CNC manages the tool life by which the tool group with the same tool type
number is considered to be one group. The tool with the same tool type
number, whose life is the shortest in the tool management data registered in
CNC, is searched when the tool type number (in T code) is commanded by
the NC program.
The magazine number and the pot number corresponding to the searched
tool
are output to the PMC as T code signal. The tool exchange (next tool) is
prepared on the PMC based on output magazine number and pot number. At
this time, it is also possible to select another tool on the PMC.
CNC counts the life of tool in the spindle position.
If the life of all tools with the tool type number commanded by T code has
been reached, P/S alarm 5317 occurs. When there is a tool in the spindle
position or the wait position, the machine continues to use the present tool
to process.
It is also possible to output not the magazine number and the pot number but
tool type number as T code signal directly by the parameter setting.
The tool life management count type is the same as the tool life management
of the past, and two kinds (the number of times and the cutting time).
The count type is set in the tool information on the tool management data.
Tool type number (T code) : Maximum of 8 digits (1 to 99,999,999)
Maximum of tool life : count 99,999,999 counts
: time 999 hours 59 minutes 59 seconds
( = 3,599,999 seconds )
Time interval of tool life count
(when counting type is specified by time) : 1 second
Tool life count restart M code : specified
Tool life count override : specified
To specify a tool directly without executing tool life management by tool
type number, program in the following format.
M(data value of parameter No.13252) T(magazine number)(pot number) ;
example )
case: the parameter No. 13252 = 333
the magazine number = 2
the pot number = 27
