10.3.3 Spare Tool Selection System
One of the following two can be selected by using a parameter for the spare tool selection system of
the spare tool selection command in tool life management II:
(1) Selection in tool registration order (When BASE SPEC parameter #1105 T-Sel2 is set to 0.)
Spare tool is selected among the used tools of a single group in the registration number order. If
used tools do not exist, spare tool is selected among unused tools in the registration number
order. If none of used and unused tools exist, spare tool is selected among normal life tools and
abnormal tools (the former is assigned higher priority) in the registration number order.
(2) Life equality selection (When BASE SPEC parameter #1105 T-Sel2 is set to 1.)
Tool whose remaining life is the longest is selected among the used and unused tools of a single
group. If more than one tool has the same remaining life, it is selected in the registration number
order. If none of used and unused tools exist, spare tool is selected among normal life tools and
abnormal tools (the former is assigned higher priority) in the registration number order.
