Title:
CHATTER VIBRATION DETERMINATION APPARATUS, MACHINE LEARNING DEVICE AND SYSTEM
Document Type and Number:
Japanese Patent JP2020138265
Kind Code:
A
Abstract:
To provide an apparatus that has a function of determining occurrence of chatter vibration according to the state of cutting and enables adjustment of a machining condition for reducing the chatter vibration as required.SOLUTION: A chatter vibration determination apparatus 1 is provided with a machine learning device configured to observe machining condition data including a feed speed and a spindle rotation speed in cutting as state data representative of the current state of environment, execute processing related to machine learning using a learning model obtained by modeling the relationship of chatter vibration with a machining condition for the cutting, based on the state data, and estimate the occurrence/non-occurrence of chatter vibration and the improvement of the chatter vibration. The chatter vibration determination apparatus outputs the result of the estimation of the occurrence/non-occurrence of the chatter vibration and the improvement of the chatter vibration.SELECTED DRAWING: Figure 2
