Abstract
A numerical controller includes: a spindle load detection unit that detects time-series data on a load on a spindle when a workpiece is machined; a machining time setting unit that sets a machining time taken in machining the workpiece; a spindle load calculation unit that, based on the time-series data, calculates a load on the spindle applied when the workpiece is machined in the machining time set by the machining time setting unit and when a feed rate of the spindle is controlled so that the load on the spindle is a constant load; and a spindle load output unit that outputs data indicating the load on the spindle calculated by the spindle load calculation unit.
Claims9
A numerical controller comprising:
- a spindle load detection unit that detects time-series data on a load on a spindle when a workpiece is machined;
- a machining time setting unit that sets a machining time taken in machining the workpiece;
- a spindle load calculation unit that, based on the time-series data, calculates a load on the spindle applied when the workpiece is machined in the machining time set by the machining time setting unit and when a feed rate of the spindle is controlled so that the load on the spindle is a constant load;
- and
- a spindle load output unit that outputs data indicating the load on the spindle calculated by the spindle load calculation unit.
A computer readable storage medium storing an instruction that causes a computer to perform:
- detecting time-series data on a load on a spindle when a workpiece is machined;
- setting a machining time taken in machining the workpiece;
- based on the time-series data, calculating a load on the spindle applied when the workpiece is machined in the set machining time and when a feed rate of the spindle is controlled so that the load on the spindle is a constant load;
- and
- outputting data indicating the calculated load on the spindle.
