Operational administration system enabling reduction in expense burden on user, and permitting manufacturer to comprehend accurately and timely operational status of machine tools on user end. Operational administration system () includes, interconnected via Internet (): manufacturer-end administration device (); operational data storage/transmission devices () connected to numerical controllers for NC machine tools (); and user-end terminal device (). The operational data storage/transmission devices () gather from the numerical controllers data pertaining to the operational status of the NC machine tools (), store the data and, when specified transmission conditions are met, send the stored operational status data to administration device () in an e-mail data format. With the received operational status data, administration device () updates operational status data it stores, and sends to terminal device (), in response to a request therefrom, machine-tool operational status data identified by user ID information appropriately input through terminal device ().

Operation management system

The invention relates to a maintenance system for machine tool. In the maintenance, system , a user management apparatus connected to a numerical control section of a machine tool , and a manufacturer management apparatus disposed on a side of a manufacturer are connected to each other via Internet . The user management apparatus collects data relating to an operating condition of each driving mechanism of the machine tool , and accumulates the data. When a predetermined transmission condition is satisfied, the user management apparatus transmits the accumulated operating condition data to the manufacturer management apparatus in the form of an electronic mail. The manufacturer management apparatus evaluates the consumption degree of each driving mechanism based on the received operating condition data, and outputs an alarm when the consumption degree exceeds a reference value.
