Title: Apparatus for detecting breakage of tool
Inventor: NAKAMURA HIDEAKI
IPC: B23Q17/09
Filed: 1984-11-08
Abstract: PURPOSE:To accurately set sensitivity without depending on the shape, material quality or surface state of a work, by providing a dummy breakage signal generation means and adjusting the sensitivity of an AE sensor. CONSTITUTION:A dummy breakage signal generator 4 and an AE sensor 6 are fixed to a work 1 at a predetermined interval, for example, at an interval of 10cm and the sensitivity of the AE sensor is set to standard sensitivity, for example, 20dB. Subsequently, a drive circuit 5 is set to the standard drive output of a tool to be used to drive the dummy breakage signal generator 4. The output level P obtained from the AE sensor 6 at this time is measured and compared with the reference output level P0 preliminarily stored in ROM10 and the ratio of both output levels is calculated as a dB value to obtain a correction value A which is, in turn, stored in the predetermined region within RAM11. Because the difference between the output levels P, P0 of both of them is dependent only on the surface roughness of the work 1, the surface state inherent to the work 1 can be corrected by using the correction value A(dB).
