Title:
NUMERICAL VALUE CONTROL DEVICE AND LEARNING DEVICE
Document Type and Number:
WIPO Patent Application WO/2022/064666
Kind Code:
A1
Abstract:
The present invention is characterized in comprising: a command generation unit (11) that analyzes a processing program (12) and generates a driving command signal, which is a control condition for controlling a motor (4) of a work machine (2); a vibration assessment unit (5) that assesses whether vibration is occurring in the work machine (2); a drive control unit (6) that, when the vibration assessment unit (5) assesses that vibration is occurring, controls the motor (4) during a change segment on the basis of a first change condition; and a learning unit (10) that generates a change condition model such that an actual change time, which is the time during which the motor (4) is controlled on the basis of the first change condition, and the maximum value of the temperature of the motor (4) during the actual change time are inputted thereto, and such that there is estimated a second change condition under which vibration of the work machine (2) can be suppressed while the maximum value of the temperature of the motor (4) is equal to or less than a permissible temperature of the motor (4).
