Emery wheel automatic tool preset and grinding status monitoring principle: material quick release of energy produces the phenomenon of Elastic wave and claims
For acoustic emission (Acoustic Emission is called for short AE).Acoustic emission is a kind of common physical phenomenon, various material acoustic emissions
The frequency range of signal is the widest, from the infrasonic frequencys of several hertz, the ultrasound wave of the audio frequency to several megahertzs of 20 Hz～20kHz.Sound is sent out
The rangeability penetrating signal is the biggest, from microcosmic dislocation motion to the seismic wave of M magnitude.But the acoustic emission letter of many materials
Number intensity is the most weak, and human ear can not directly be heard, needs just can detect by sensitive electronic machine.By instrument detection, note
Record, analyze acoustic emission signal and utilize the technology of acoustic emission signal to be referred to as acoustic emission.
Grinding process is a process the most complicated, and grinding area has at a relatively high deformation rate and fretting wear and phase
Become, impact, the phenomenon such as the impact collapsing broken, cutting fluid of sand grains, these are all strong acoustic emission sources.Emery wheel and workpiece elastic connecting
Touch, emery wheel bonding agent ruptures, emery wheel abrasive particle collapses broken, emery wheel abrasive particle and all can launch with friction of workpiece, surface of the work crackle process etc.
Go out elastic wave.AE signal and workpiece material, grinding condition, the factor such as state of wheel face suffer from close relationship.These
The change of factor will necessarily cause the aspects such as the amplitude of acoustic emission signal, frequency spectrum to change.Utilize this feature, can pass through
The change of detection acoustic emission signal, it is achieved with absorption surface state and the monitoring of grinding status.Emery wheel automatic tool preset and grinding shape
State monitoring system is made up of acoustic emission sensor, grinding machine X-axis and Z axis grating scale and computer data acquisition and treatment system.
