Abstract
A numerical controller performs control for changing a tool mounted on a spindle to another tool stored in a tool magazine based on a machining program. The numerical controller analyzes a command by a block of the machining program, predicts a time required for machining by the analyzed command, and selects a tool changeable before a tool change command, during tool selection, based on the predicted time.
