Description
Technical field
The present invention relates to ultrasonic cavitation detection and signal analysis technologies in ultrasonic compound process, more particularly to one kind is for surpassing
The on-Line Monitor Device of sound ELID internal grinding cavitation effects.
Background technology
The hard brittle materials such as engineering ceramics, optical glass have high temperature resistant, resistant to chemical etching, high temperature creep-resisting, low thermal expansion
The features such as coefficient, becomes the hot spot of the application fields such as military project, space flight, precision instrument, machine tool industry concern, but due to the material
The big work in-process of difficult processing characteristics, such as brittleness is easy to generate multiclass damage, is restricted to be allowed to apply.To solve this
A little problems, in recent years many researchers the efficient ultraprecise processing method of this kind of hard brittle material is studied, it is such as hard crisp
The pre-stressed machining method of material, ELID Ultra-precision Turnings method, magnetic polishing technology, Ultrasonic machining technology etc..In these processing sides
In method, ELID ultraprecise processing methods and Ultrasonic machining technology belong to the superfine processing method of current comparative maturity：ELID superfinishings
Close processing method enables grinding wheel to obtain restoring on line, and grinding efficiency is significantly increased, but on the whole, and efficiency is in the application still
It is relatively low；Ultrasonic machining can effectively improve grinding surface quality, increase substantially grinding efficiency, but grinding wheel can not achieve online
Finishing.Therefore, ultrasonic vibration and ELID processing methods is mutually compound, in conjunction with the advantage of both processing methods, form a kind of needle
Seem particularly necessary to the minute surface High Efficient Machining Technology of hard brittle material.
In this novel ultrasonic ELID Combined Machining Technologies, the processing mechanism of common ELID grindings has occurred significantly
Variation, most obvious one is exactly that this new processing technology that is added to of ultrasonication brings cavitation effect.Cavitation effect
The noise and vibration of generation will generate a series of influence to this new Combined Machining Technology, such as on the one hand it can be limited in
The sound and vibration intensity propagated in liquid, on the other hand it, which also will produce the speed of a series of physical-chemical process, significantly affects,
Therefore the cavitation effect in research ultrasound ELID composite grindings has the science essence for disclosing this new Combined Machining Technology
There is important meaning.
It is measured generally for cavitation effect, is by a series of physics, chemical method, subharmonic such as physically
Method, the release of chemical iodine and electric method, and with the development of science and technology, occur using high-speed photography and 3D hologram skill
Art visually discloses the method with research ultrasonic cavitation process.Electrical method is so that water is become electrolyte by cavitation effect,
Conductivity increases, by the variation for detecting conductivity, you can the case where studying cavitation effect；Iodine release is to utilize ultrasonic cavitation
In the process, the KI oxidations in KI solution generate iodine, and a small amount of CCl4 is added, iodine is made largely to be precipitated, and make iodine again after starch is added
It blue is showed, then is titrated with sodium thiosulfate, solution restores to gradually become again colourless, passes through and detects sodium thiosulfate
Amount is assured that the amount of precipitation of iodine, and then obtains cavitation intensity；High speed video process records X-Y scheme in real time using high speed camera
Picture, this method can not only measure Air Bubble Size such as radius, can also obtain the true form of bubble, but the cost of this method
It is higher；Sonoluminescence imaging is to will produce high pressure and temperature within the moment caved in, bubble using cavitation bubble, to
Launch a kind of dim light, when the conditions such as frequency, the temperature of the sound intensity, liquid of ultrasound change, Sonoluminescence intensity will
Significant change occurs, by observing the variation and distribution of light-emitting zone in liquid, analyzes the variation feelings of liquid hollow effect
Condition.
All there is certain limitation in reaction process, measurement accuracy, measurement cost, real-time detection etc. in these methods
Property.Such as electrical method, iodine release needs carry out complicated physical chemistry transformation, and experimentation is complicated, and result is not yet
It is enough accurate, it can only reflect Cavitation Characteristics indirectly；Although high speed video process is intuitive, general device is more expensive, it is desirable that experiment
Condition is higher；The obtained data discrete degree of sonoluminescence imaging method is larger, simultaneously because Wen Sheng in cavitation processes, atomization with
And the reasons such as loss of luminol, make flashing, the time for exposure is longer, it is difficult to do fine analysis from imaging.
