Abstract
A machine tool management system connects an external server and a large number of NC devices controlling the external server and respective machine tools through a network. The system collects several kinds of signal data from the NC device of each machine tool to the external server. In the system, the external server collects an estimated thermal distortion from the NC device and compares the estimated thermal distortion with pre-stored data to determine whether the tool is machining favorably.
Claims3
A machine tool management system, comprising:
- an external server;
- and
- a plurality of numerical controller (NC) devices connected to the external server through a network, the NC devices controlling respective machine tools,
- wherein the external server is configured to collect operating information obtained from the NC device of each machine tool, and comprises:
- storing unit storing a maintenance period model and a refinement algorithm in advance;
- changing unit changing a computational expression of the maintenance period model by the refinement algorithm;
- and
- computing unit obtaining a next maintenance period from the maintenance period model.
