Abstract
A numerical control device includes: an estimation unit to estimate an accumulation amount of swarf to be produced when a tool mounted on a machine tool cuts a workpiece on the basis of a machining condition in cutting the workpiece by the tool and a value of current to be applied to a motor for moving a shaft of the machine tool when the tool cuts the workpiece. The numerical control device further includes a correction unit to correct the accumulation amount of swarf estimated by the estimation unit on the basis of a machining mode specifying a shape of swarf to be produced when the tool cuts the workpiece.

A numerical control device comprising:
- an estimator to estimate an accumulation amount of swarf to be produced when a tool mounted on a machine tool cuts a workpiece, the estimator estimates the accumulation amount of swarf on the basis of a machining condition in cutting the workpiece by the tool and a value of current to be applied to a motor for moving a shaft of the machine tool when the tool cuts the workpiece;
- and
- a corrector to correct the accumulation amount of swarf estimated by the estimator on the basis of a machining mode specifying a shape of swarf to be produced when the tool cuts the workpiece, wherein
- the machining mode specifies any one of relation between a rotating direction of the motor and the shape of the swarf, relation between a purpose of current flowing in the motor and the shape of the swarf, and relation of the rotating direction of the motor and the purpose of current flowing in the motor with the shape of the swarf, and
- the corrector determines whether the swarf will be continuous or divided into a plurality of chips on the basis of the machining mode, and corrects the accumulation amount of swarf on the basis of a result of the determination.
