Chatter vibration detection device, chatter vibration detection method, chatter vibration detection program, and chatter vibration suppression device

摘要

PROBLEM TO BE SOLVED: To detect chatter vibration with high accuracy. A chatter vibration detection device (100) is a device that determines the presence or absence of chatter vibration based on sensor data (D0) output from a sensor (204) that detects the vibration of a cutting tool (201) of a processing device. That is, the first storage unit (101) that stores the labeled sensor data (101a) and the first storage unit (101) that extracts one or more first feature amounts from the labeled sensor data as learning data (L2). From the sensor data and the second extraction process of extracting the determination target data (D2) including one or more second feature quantities from the sensor data, and the learning data. A chatter vibration learning unit (104) that generates a learning model (105a), and a chatter vibration determination unit (106) that determines whether or not the determination target data is data that indicates chatter vibration.
