Recommended maintenance notification system

Abstract

First and second machine tools machine a workpiece and transmit machine status information each representing the status thereof to a server. A measurement device measures the workpiece machined by the first machine tool and transmits workpiece information representing a status of a defective workpiece to the server. The server includes a machining accuracy defect countermeasure database storing the status of the defective workpiece and a corresponding maintenance content, a machine status database storing the machine status information on the first and second machine tools, and a notification unit that extracts the maintenance content corresponding to the status of the defective workpiece when the status of the workpiece included in the workpiece information and the status of the defective workpiece included in the machining accuracy defect countermeasure database are similar to each other, and that outputs a notification recommending execution of the extracted maintenance content in the second machine tool when the machine status information on the first machine tool and the machine status information on the second machine tool are similar to each other.
