Tools are classified into some groups. For each group, a tool life (time
or frequency of use) is specified. Each time a tool is used, the time for
which the tool is used is accumulated. When the tool life has been
reached, the next tool previously determined in the same group is used.
This function is called the tool life management function.
With 2–path control, tool life management is performed for each tool post
separately. So tool life management data is also set for each tool post.
Tools used sequentially in each group and their tool life are registered in
the CNC as following program format of table 11.2.1(a).
