It is a cantilever beam during using cutter zero load (i.e. not in contact with to workpiece), geo-stationary, when point of a knife touches workpiece,
The state of knife bar original stationary cantilever beam is broken, and can produce vibration, by perceiving and detecting a vibration, thus reach perception connecing
Touch and understand the purpose of cutting output.
Concrete technical scheme is：
One piezoelectric ceramic vibration sensor is installed on cutterhead additional, for the vibration of sensitive cutter head.Once cutter head and quilt
Work piece surface contacts, and piezoelectric ceramic vibration sensor sensitive can arrive microvibration, by being amplified this vibration signal, no
Line transmitting, wireless receiving, signals revivification, audio output and vibrational waveform such as show at the operation, reach the perception actual Fine Feed of cutter
The purpose of amount.
Wherein said piezoelectric ceramic vibration sensor vibration signal is converted into voltage sensitive to after the vibration of point of a knife
Signal, then input signal harvester and emitter, signals collecting and emitter are amplified to the voltage signal of vibration, and lead to
Cross wireless transmitter module to launch, after wireless signal receiver receives this signal, its carrier signal can be reduced to vibrate
Signal, selects exports audio signal to deliver to 3.5mm earphone interface for monitoring by selecting switch, or selects vibrational waveform output
To oscillograph, it is directly monitored by vibrational waveform, realize the purpose of detection cutter actual Fine Feed amount by both forms.
It is an advantage of the current invention that：The present invention is touched using the point of a knife of cutter and knife bar can be led to during work piece to vibrate,
Micrometer is realized by the principle detecting this vibration signal.Wherein the vibration signal detecting is converted to voltage by vibrating sensor
Signal, is amplified through signal picker, and is sent by wireless transmitter module；Wireless receiving module is received and is reduced,
Finally by oscillograph export vibrational waveform, or 3.5mm earpiece audio output, to be monitored with this or to monitor point of a knife with processed
The contact situation of workpiece, and then realize the purpose of the actual Fine Feed amount of perception and detection cutter, simply easily realize, Er Qiezhun
Really, it is particularly well-suited to the detection of the cutter of Fine Feed amount (0～2 μm), it is demonstrated experimentally that process distinguishing is good, solve in engineering
The long-term technical problem not solved.Additionally, it is real to realize detection cutter by earphone interface for prison and oscillograph both forms
The perception of border Fine Feed amount, is particularly easy to realize, simple, visual result, creative.
