10.3 TOOL LIFE MANAGEMENT FUNCTION
General
Tools are grouped and the tool life (use count or use time) is
predetermined for each group. Each time a tool belonging to a group is
used, its life value is incremented. Once the predetermined tool life
value is reached, a new tool is automatically selected according to the
predefined tool order in the group. This allows continuous machining
as well as tool life management.
The tool life management data, including tool group numbers, tool life
values, and tool compensation codes, is stored in the CNC.
