Abstract
Provided is a tool life estimating device that enables estimation of a life of a tool used in a machine tool according to changes in machining conditions. The tool life estimating device includes a state observation unit that acquires machining information indicative of a status of the machining in a state where the life of the tool remains sufficiently, wherein the machining information is acquired from log data recorded while the machine tool is operated, and creates input data based on the machining information that has been acquired; a learning unit that constructs a learning model in which clusters of the machining information are created by unsupervised learning using the input data that has been created by the state observation unit; and a learning model storage unit that stores the learning model.
Claims3
A tool life estimating device for estimating a life of a tool used by a machine tool for machining a workpiece, the device comprising:
- a state observation unit configured to acquire machining information indicative of a status of the machining in a state where the life of the tool remains sufficiently, the machining information being acquired from log data recorded while the machine tool is operated, and configured to create input data based on the machining information that has been acquired;
- a learning unit configured to construct a learning model in which clusters of the machining information are created, the learning model being constructed by unsupervised learning using the input data created by the state observation unit;
- and
- a learning model storage unit configured to store the learning model.
