    摘要: In milling operations, periodically sensed vibration signals synchronous with tool revolution enables a determination of whether the tool returns to approximately the same position each revolution. If so, stability is indicated by tightly grouped values of the periodically sensed vibration signal. If the tool does not return to the same position, spread in the value of the periodically sampled vibration signals is produced thereby indicating chatter conditions. Variance values may be calculated and displayed; histograms may be produced and displayed; corrective action, if needed, may be taken in response to the variance values and/or histogram. Nominal (or commanded) spindle speed, while not necessarily exactly synchronous with actual tool rotation, is entirely adequate to trigger samples and achieve clear indication of the presence or absence of chatter.

    摘要: An acoustic pretouch sensor or proximity sensor (110) includes a cavity (104) with a first microphone (106) disposed therein, and optionally a second microphone (108) disposed outside of the cavity. A processing system (110) receives the signals generated by the first microphone and analyzes the spectrum to produce a result representing the resonant frequency of the cavity. The processing system may optionally subtract the second microphone signal spectrum from the first to automatically compensate for changes in ambient noise. The processing system uses the resonant frequency to estimate the distance from the cavity opening to a surface (90). For example, the pretouch sensors may be incorporated into a stand alone device (100), into a robotic end effector (204), or into a device such as a phone (300).

    摘要: A microphone senses the sound generated by a tool cutting a workpiece. The sound is analysed and compared to prior known sounds of good and bad cutting operations by an audio-processing device, and computer-controlled feedback is provided to control the tool and/or workpiece appropriately. The system can improve the quality of its feedback as a result of experience with particular tools and workpieces.
