Tool life management function enables uniform quality machining by managing tool life and exchanging tools at proper timing.
This function manages tool life by comparing the time (or the number of cuttings) of each tool which is set before machining
and the cumulative cutting hours (or the cumulative number of cuttings).
When a tool has reached the end of its tool life, the signal is output to notify users.
There are two types of tool life management: I and II. The function which notifies that the tool reaches the end of its tool life is
featured in tool life management I.
Tool life management II features the following functions, in addition to the said notification function:
