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.
Claims5
A numerical controller for performing control for changing a first tool mounted on a spindle to a second tool stored in a tool magazine based on a machining program, the numerical controller comprising:
- a command analysis unit for analyzing a command by a block of the machining program;
- a machining time prediction unit for predicting a time required for machining by the command analyzed by the command analysis unit;
- and
- a tool selection unit for selecting a tool which can be changed before a tool change command during tool selection, as the second tool, based on the time required for machining by the command predicted by the machining time prediction unit.
