Description
Technical field
The present invention relates to a kind of grinding wheel dressing methods, and laser reconditioning forming grinding wheel is detected more particularly to a kind of view-based access control model
Device and its dressing method.
Background technology
It is set as the difficult-to-machine materials device such as engineering ceramics, optical glass and hard alloy is widely used in all kinds of keys
Standby, the grinding of various Complex Surface Parts gradually increases, while various Complex Surface Parts are by ultra band shaping sand again
Wheel carries out grinding.Ultra band shaping grinding wheel refers to cubic boron nitride, diamond forming grinding wheel, as shown in Figure 1.It has very
Good grinding characteristic, such as:The hardness etc. that antiwear property is strong, thermal conductivity is good, high, but have just because of ultra band shaping grinding wheel
There is the above characteristic that its finishing processing is caused to become extremely difficult.Therefore, in order to make ultra band shaping grinding wheel in Grinding Process
Correct geometrical precision and certain abrasive grain can be kept sharp, it is necessary to periodically be modified to ultra band shaping grinding wheel.
Since forming grinding wheel type is various, used dressing method also differs widely, presently the most universal at molding sand
The method that dressing method still uses manual amendment is taken turns, but this method dressing efficiency is low, and it is difficult to ensure that after finishing
Contour accuracy.Although there are many new finishing processing methods, such as：Turning dressing method, grinding dressing method, idler wheel finishing
Method, electric spark shaving method, on-line purification method etc., but still there is also many disadvantages, such as：Grinding performance is poor, grinding wheel shape
Shape precision is low, dressing efficiency is low, the cost is relatively high, processing environment requires height, and can not accomplish to detect forming grinding wheel in real time
Whether finishing is up to standard, and dressing accuracy is low, is not suitable for the efficiently high-accuracy finishing of forming grinding wheel.
Meanwhile forming grinding wheel contour detecting technology mainly by super depth of field 3-D scanning microscope or directly to workpiece into
Effect after grinding is observed in row grinding, the disadvantage is that：The former is more demanding to use environment, usually requires that in dustless ring
Border carries out, therefore also needs to grinding wheel after grinding machine dismounting, could be observed, using cumbersome, and the equipment price
Costliness, working service cost are higher.Although the latter is low compared with the former use cost, operation implements relatively easy, real
Border situation, which is forming grinding wheel profile modifications, can reach required precision in first time finishing, therefore is also needed to grinding wheel
It removes, redresses from grinding machine, be then installed in the effect of workpiece after carrying out the observation grinding of grinding again on grinding machine
Fruit, although this method operation is upper relatively easy, workload is huge when being embodied, it has not been convenient to and factory efficiently produces and processes,
Have an effect on manufacturing schedule simultaneously.
Currently, with vision detection technology progress, object to be detected is set to image in camera by optical component
On photosensitive element, it may be implemented, to image digitazation, then image to be handled and detected by computer, can accomplish non-
Accurate measurement is contacted, the interference caused by subjective factors artificially detected is excluded, production effect can be further increased by integrated automatic equipment
Rate.It is modified simultaneously by the way that the contactless online forming grinding wheel of forming grinding wheel may be implemented in conjunction with laser reconditioning, passes through CCD camera
Acquire forming grinding wheel edge contour information, using computer control algorithm to the feature contour information of forming grinding wheel be identified with
Then extraction carries out similarity with the forming grinding wheel edge contour feature of standard and compares, detect to be trimmed to lacking for abrasive wheel
Region is fallen into, computer makes the three-dimensional mobile station edge for loading laser ablation head by planning that the output phase answers NC control instructions automatically
It specific track to be moved, the defect area of forming grinding wheel, which is carried out laser ablation, using the high energy laser beam after focusing goes
It removes, to make forming grinding wheel reach defined geometry, realizes the finishing of forming grinding wheel.
With the development of Computer Control Technology, it is combined with both laser precision machinings by vision detection technology, it can
To realize high efficiency, high-precision, full-automatic forming grinding wheel in machine dressing process, and forming grinding wheel laser trimming techniques are not yet
It is limited only to super hard abrasive and precise treatment direction is developed, but intelligent direction development of gradually marching toward.
