Abstract

Learning related to a device having a driving unit is performed more easily. An information processing device includes: a storage unit that stores a machining program for operating a motor of a machine tool, a robot, or an industrial machine; and a generation unit that generates a learning program for performing learning based on operating characteristics of the motor by extracting a partial machining program including a characteristic element from the machining program stored in the storage unit.

First claim

What is claimed is:

1 . An information processing device comprising:
a storage unit that stores a machining program for operating a motor of a machine tool, a robot, or an industrial machine; and a generation unit that generates a learning program for performing learning based on operating characteristics of the motor by extracting a partial machining program including a characteristic element from the machining program stored in the storage unit.

2 . The information processing device according to claim 1 , further comprising:
a learning unit that operates the motor on the basis of the learning program generated by the generation unit and performs learning based on the operating characteristics of the motor; and an adjustment unit that adjusts control parameters of the motor on the basis a learning result obtained by the learning unit.

3 . The information processing device according to claim 1 , wherein
as the partial machining program including the characteristic element, the generation unit extracts a machining program including at least one of: a machining program for causing the motor to perform an operation involving reversal of a motor speed, a machining program for causing the motor to perform an operation involving a switching from a stopped state to a moving state and a switching from a moving state to a stopped state, and a machining program for causing the motor to perform an operation involving a change in acceleration without involving reversal of a motor speed.

4 . The information processing device according to claim 1 , wherein
the generation unit extracts a machining program for causing the motor to perform an operation in which a positional deviation exceeds a threshold when the motor is operated as the partial machining program including the characteristic element.

5 . The information processing device according to claim 4 , wherein
the generation unit determines whether the positional deviation exceeds a threshold on the basis of a result obtained when the motor is operated on the basis of the machining program.

6 . The information processing device according to claim 1 , wherein
the generation unit extracts a partial machining program designated by a user who has referred to information indicating a change in positional deviation in a time-series manner or information on a moving trajectory of the operation of the motor as the partial machining program including the characteristic element.

7 . The information processing device according to claim 1 , further comprising:
a display unit that displays the partial machining program extracted by the generation unit.

8 . An information processing method executed by a computer, comprising:
a storage step of storing a machining program for operating a motor of a machine tool, a robot, or an industrial machine; and a determination step of generating a learning program for performing learning based on operating characteristics of the motor by extracting a partial machining program including a characteristic element from the machining program stored in the storage step.
