发明名称 METHOD OF SENSING FAILURES AT THE TIP OF CUTTING TOOL
摘要 PURPOSE:To sense failure or wear of the edge of a cutting tool by providing acoustic emission sensor at that side of rotating work nearer to the chuck. CONSTITUTION:When a work to be processed 2 is grasped by a chuck 5 with its nails 4 to be machined by a tip 3, this tip 3 may have a failure, and at this time an acoustic emission signal (AE signal) is produced, that is sensed by a sensor of the AE sensor transmission set 1 furnished at the side of work nearer to the chuck 5, and the signal obtained is transmitted by a transmitter amplified by an amplifier. The signal transmitted is received by a receiver 6 situated away form the cutting tool to be amplified by an amplifier 7, and is transmitted to an alarm 9 through a signal output amplifier 8. There an alarm is given about wear or failure of the tip 3.
