Document Type and Number:
WIPO Patent Application WO/2019/186620
Kind Code:
A1
Abstract:
This abnormality sign detection device, for detecting signs of abnormality in a tool used in machining is provided with: a data collection unit which collects vibration data about a tool during machining; a model construction unit which sets the vibration data collected by the data collection unit during a prescribed period at the beginning of machining as data in a normal region, and constructs a determination model in a one-class support vector machine; and a sign detection unit which detects whether or not there are signs of an abnormality in the tool by using the determination model constructed by the model construction unit to determine whether or not the vibration data is contained in the normal region.
