Management system, management device, spindle failure detection method using management device, and non-transitory computer readable medium encoded with computer program

Abstract

A management system including a network, plural manufacturing cells connected to the network, and a management device that is connected to the network and manages the plurality of manufacturing cells, in which the manufacturing cell includes: a machine tool; and a control device that controls the machine tool, analyzes a vibration state of a spindle positioning shaft of the machine tool, and sends an analysis result via the network; in which the management device includes: a communication unit that receives the analysis result sent by the control device; and a detection unit that compares the analysis results thus received, and compares vibration states of the machine tool of each of the manufacturing cells, so as to detect spindle failure of any of the machine tools; and in which the communication unit, in a case of the detection unit detecting the spindle failure, sends a failure signal via the network.
