MACHINING ABNORMALITY DETECTING METHOD AND DEVICE, AND MACHINING CONTROLLER

摘要

PROBLEM TO BE SOLVED: To previously prevent the generation of abnormality in the machining by an NC machine or the like. ;SOLUTION: This machining abnormality detecting device for a work 2 machined by bringing the work 2 into contact with a machining tool 3 and relatively moving them, comprises a vibration amplitude detecting means 8 for detecting at least one of amplitude by vibration of the machining tool 3 during the machining, and that of the work 2 under machining, and the judging means 9, 10 for judging whether the machining condition is normal or not on the basis of at least one vibration detected by the vibration amplitude detecting means 8.;COPYRIGHT: (C)2000,JPO
