14.15 Tool Life Management (Machining Center System)

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.

Cumulative cutting hours indicates the length of time the tool was engaged in cutting, while "cumulative number of cuttings"

indicates the number of times the tool was mounted on the spindle. You can specify which method to monitor the tool life by

setting the lowest one-digit number of "Method" on the tool life management screen.

There are three types of tool life management: I, II and III. The function which notifies that the tool reaches the end of its tool

life is featured in tool life management I and III.
