Numerical controller
A numerical controller which controls a machine tool acquires tool information including a shape of a tool, a machining condition in machining, and information related to a machining result of a workpiece after machining. A machine learning device performs machine learning on tendency of the information related to a machining result with respect to the tool information and the machining condition based on the tool information and the machining condition used as input data and based on the information related to a machining result used as teacher data, so as to construct a learning model. The machine learning device determines whether or not a machining result is good by using the learning model based on the tool information and the machining condition before the machine tool machines a workpiece.
1. A numerical controller which controls a machine tool machining workpiece with a tool, the numerical controller configured to:
acquire tool information including a shape of the tool;
acquire a machining condition in the machining of the workpiece; and
acquire information related to a machining result of the workpiece after the machining of the workpiece; and
wherein the numerical controller comprises a machine learning device which performs machine learning on tendency of the information related to a machining result with respect to the tool information and the machining condition based on the tool information and the machining condition used as input data and based on the information related to a machining result used as teacher data, so as to construct a learning model, and wherein
the machine learning device is configured to determine whether or not a machining result is good by using the constructed learning model based on the tool information acquired by the shape data acquisition unit and the machining condition acquired by the machining condition acquisition unit, before the machine tool machines the workpiece.
2. The numerical controller according to claim 1 , wherein the machine learning device constructs a learning model by a multilayer neural network.
