摘要： PURPOSE:To detect exactly a breakage of a tool by analyzing an acoustic emission (AE) signal in a frequency area. CONSTITUTION:At the time of a regular cutting work, a power spectrum distribution of an AE signal is concentrated to around a frequency 50kHz, and it is attenuated monotonously in a higher frequency area than said frequency. On the other hand, a power spectrum distribution of the time when a tool is broken has a peak in the vicinity of a frequency 300kHz.

摘要： PURPOSE:To increase the S/N of an AE (acoustic emission) wave by detecting two sensors, and delaying the output of a sensor closer to the AE source by 90 deg. and adding the delayed output to the output of the other sensor. CONSTITUTION:The AE wave generation source 2 is provided on a body 1 to be tested and the two resonance type sensors 3 and 4 are arranged facing the AE wave generation source 2. The distance between those sensors 3 and 4 is l=lambda (1/4+n). In this case, lambda is the wavelength of an acoustic wave and (n) is 0 or a positive integer. The output of the sensor 4 close to the AE wave generation source 2 is inputted to a phase shifter 5 and delayed by 90 deg.. The 90 deg.-delayed output is added to the output of the other sensor 3 by an adder 6 to detect the AE wave. Thus, the output of the sensor close to the AE wave generation source is delayed, so an acoustic wave arriving except in the direc tion of the predetermined source source is canceled to increase the S/N of the AE wave, detecting the output precisely.
摘要翻译：目的：通过检测两个传感器来增加AE（声发射）波的S / N，并将传感器的距离延迟到AE源近90度。并将延迟输出添加到另一个传感器的输出。构成：AE波生成源2设置在待测试的主体1上，并且两个谐振型传感器3和4布置成面向AE波发生源2.这些传感器3和4之间的距离为l =λ（1 / 4 + n）。在这种情况下，λ是声波的波长，（n）为0或正整数。靠近AE波发生源2的传感器4的输出被输入到移相器5并延迟90度。90度延迟的输出通过加法器6相加到另一个传感器3的输出端检测AE波。因此，靠近AE波发生源的传感器的输出被延迟，因此除了在预定的源极的方向之外到达的声波被消除以增加AE波的S / N，从而精确地检测输出。

摘要： 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).
摘要翻译：目的：通过提供虚拟断裂信号发生装置和调整AE传感器的灵敏度，精确地设定灵敏度，而不依赖于工件的形状，材料质量或表面状态。构成：虚拟断裂信号发生器4和AE传感器6以预定间隔例如以10cm的间隔固定到工件1，并且AE传感器的灵敏度被设置为标准灵敏度，例如20dB。随后，将驱动电路5设置为用于驱动虚拟断裂信号发生器4的工具的标准驱动输出。此时测量从AE传感器6获得的输出电平P，并将其与参考输出电平进行比较 P0预先存储在ROM10中，并将两个输出电平的比率计算为dB值，以获得校正值A，该校正值A又被存储在RAM11内的预定区域中。由于两者的输出电平P，P0之间的差仅取决于工件1的表面粗糙度，所以可以通过使用校正值A（dB）来校正工件1固有的表面状态。

摘要： PURPOSE:To provide a self-diagnostic function by outputting a signal indicating a signal which is transmitted continuously all the time is not received if a device which senses the continuously transmitted signal and decides on normality is abnormal. CONSTITUTION:For example, when a drill 4 is abnormal, the waveform of a generated AE (acoustic emission) wave is checked by a tool abnormality detection sensor 1 and an arithmetic part 2 makes a decision. Further, a signal generating circuit 8 is excited by an oscillator 10 as an exciting device to output an AE wave having a different frequency and waveform all that time when the tool is abnormal. A diagnostic device 9 is provided to the arithmetic part 2 and the AE wave generated by the device 8 is received through a machine table 3, sensor 1, and lead wire 11 and outputted when there is not reception. The moment the device 9 judges that no signal is received, that is outputted to the controller 6 of the machine through a signal line 12. Consequently, the abnormality of the device itself is detected.

摘要： PURPOSE:To make it possible to simply and certainly set an adequate comparison reference value regardless of various elements, by multiplying a detection level, at the point of time when the rising change ratio of the AE level during a period directly after the beginning of processing is lowered, by a difinite quantity ratio. CONSTITUTION:Acoustic emission (AE), which is generated in a drill when a hole is opened to a workpiece 3 by a drilling in such a state that an AE sensor 2 is attached to the main body side of a boring machine 1, is detected by said sensor 2. The output of the sensor 2 is amplified to a predetermined level by an amplifier circuit 6 and, thereafter, a band component is taken out by a band pass filter (BPF) 7 to rectify a detector circuit 8. The output of the circuit 8 is succeedingly monitored by CPU11 through an A/D converter 10 and a detection output value, at the point of time when the change ratio of said output is lowered to a definite value or less, is detected and CPU11 feeds out the value, which is obtained by multiplying said detection value by a definite quantity ratio by a D/A converter 14, as the comparison reference value of a comparator circuit 9.

摘要： A system for flaw detection during a continuous welding process uses a transducer to provide a signal burst for each acoustic burst from an article being welded. The signal burst is amplified and filtered to pass frequencies between about 100 and about 550 KHz. The ring-down counter counts signals of the filtered signal burst. The first signal of the filtered signal burst initiates a timing circuit that times out to provide a reset pulse to reset the ring-down counter. If the decimal count exceeds 100 but does not exceed 1000, the ring-down counter operates circuitry to provide a latched signal to an output of a flip-flop to enable a gate before the counter is reset by the reset pulse of the timing circuit. That reset pulse is also provided to the gate to provide at its output a pulse representing one filtered signal burst having more than 100 and no more than 1000 signals during the timing operation. The pulses from the gate are inputs to a pulse counter in the counter mode and a retriggerable monostable multivibrator that, if not retriggered by the next pulse before a predetermined time, resets another flip-flop and resets the pulse counter. If the pulse counter counts a predetermined number of pulses before it is reset, it sets that another flip-flop to provide a signal to an alarm device that turns on a light indicating that there is a weld flaw.

摘要： PURPOSE:To easily foresee break of a tool by detecting elastic waves including supersonic vibration from a torque limiter and detecting a condition before the break by the captioned device which performs in-process detection of an abnormal condition such as damage, break and the like of a cutting tool. CONSTITUTION:When a drill 1 is overloaded during cutting due to plugging of chips or the like and there is a fear of break of the drill 1, a torque limiter 3 repeats joining and disjoining movements and produces elastic waves including a high level of supersonic waves. The elastic waves pass through a tooling 4, bearing 7 and are transmitted to a main shaft head 6, and then detected by a detection part 12. However, a noise of the elastic waves detected by the detection part 12, after being excluded by means of a bypass filter 13, is amplified by means of an amplifier 14 and demodulated by a detector 15. This output is compared with a set value by means of an amplitude selector 16 and in case it exceeds the set value, a signal generator 17 gives an alarm.
