Aperture adds the penetrable detection algorithm of labour

Research proved, penetrable detection algorithm can improve the consistency of stiletto, what it explores stiletto place to need pulse when Kong Gang has been hit is actual a number, undertake after that appropriate, the operation that defines oneself by the user. The penetrable exploration method that uses in the laser beam machining that has discussed before exploration method 1, 2 have the following collective place it seems that. Above all, they use special sensor, because this increased cost and complexity to the system. Next, sensor normally by adscititious go up to the smooth road of laser, this installs specialized enough and firm equipment with respect to need, in order to protect the effect that sensor avoids the fragment that suffers laser bore, and shun work or the collision that clamping apparatus brings. Below a few circumstances, sensor limitted the effective job scope of laser system. The technique that this article place discusses (already undertook American patent applies for) used camera to regard as send feeling equipment. Camera is the standard component of a typical laser stiletto system, its installation makes it can be photographed to the area of stiletto picture, its direction and the laser light beam that undertake stiletto are coaxal (see a picture 1) . In addition, this technology was used outside buy the electron that reachs own research and development and mechanical package, will adjust radiant of laser stiletto process is smooth, and process video signal. The signal of camera is arrived to penetrate by feedback in exploration processor, compare signal extent and a value photograph of predefine, this value answers relatively with the case with penetrable alveolus. Arose " penetrable already " after signal, began next step -- put out shutter, continue to move the position of next aperture, perhaps continue to convey to define the additional pulse of a number oneself by the user. SPC data collects software to be able to be used to the pulse number that the record penetrates place needs, and estimate the real time of this parameter go situation. This data is very useful to exploring beam of light to transmit the pollution of package, can explore cranial of focusing lens lens to slide for instance, avoid it to bring adverse effect to the quality of aperture. Penetrate exploring is by CNC stiletto programme controll, command of its use M64 will indicate a system to open shutter or when next course module is carried out again after penetrable exploration command. A typical penetrable exploration order is M64 N2 X15 E3. The meaning of parameter is respectively inside this group: ◆ Nx, x is transmission pulse the least value of several. The system always transmits this numerary pulse, although convey in pulse,explore before already penetrating still also is to undertake transmission. Its acquiesce is worth for 0. ◆ Xm, m is transmission pulse the maximum of several. If be in,had not explored penetrable, treatment stops, the system signs up for a fault. This parameter must is more than 0. ◆ En, n is to be in the pulse that explores penetrable succeed add to transmit several. Its acquiesce is worth for 0, do not have additional pulse namely. In explore after penetrating, the system continues to transmit N additional pulse (unless here pulse already achieved the biggest numeric M before) . Nextpage machines a process to advance and improvement equips, laser controlled a system to include oscillograph card, in order to serve as the component of penetrable exploration equipment. Oscillograph uses the signal of indication camera, the output of comparator, show signal of laser synchronism pulse, these pulse are to be in installation and / in perhaps running a course, will start video to catch. Graph 3 (a) used penetrable detection algorithm (3 pulse) was used after penetrate, with use secure a several pulse photograph to compare, got more consistent exit aperture diameter. (The result of test of shape of a distribution of normalization of exit aperture diameter in B) (a) - in the process that bore diameter is using this technology, the test workpiece that penetrates the dimension that explores pair of aperture sheds successional influence to be able to adopt a standard compatibly will estimate, it included a few area that have 30 opening, be in with 30o bore of surface of Inconel 718 material (see a picture 2) . The bougie that the diameter that aperture enters the mouth is defined to be the biggest diameter also 25% of deepness of can thorough aperture. The diameter that aperture exports can be extended for the bougie of the biggest diameter by the definition inside limits of whole aperture length. Graph 3(a) gave out to use penetrable explore and use the pulse that secures a number (without penetrable explore) the enters Kong He to export aperture diameter that gets below two kinds of case distributings. Of the exit aperture diameter that gives out in graph 3(b) distributinging is the data that comes from graph 3(a) . These curves say to palpability is used and be not used penetrable explore come below two kinds of circumstances of bore, undesirable exit aperture diameter is in 2% less than, using penetrate exploration situation falls, of hole size distributing more narrow. Two kinds of cases that successive air current is being used and did not use penetrable test fell to get additional test version again. Using the test version that penetrable test gets is to be in explore after penetrating, added again 0 get to 3 additional pulse. Two groups of additional test version used the pulse that secures a number (4 mix 5) come to what bore gets. Air current of use Habco AF100T checks workbench to finish what the section that contains 30 alveolus to each has air stream to measure. Graph the 4 standard deviation that summed up air current to measure an outcome. Graph the deviation of air current standard of spile of place of 4 courses laser. Alveolus is be being used and did not use what penetrable test gets below two kinds of case.

Data shows the two air stream that can receive to 3 additional pulse are used after penetrate consistency is best.

Can get from inside data below two conclusion: 1.

After penetrate need joins additional pulse (two go to 3) will receive successive air stream. After should penetrating, if do not use additional pulse, can reduce pair of rear destruction, but this consistency sacrificial alveolus. 2.

Used penetrable explore, transmit again in penetrable succeed add two to 3 pulse, this and use photograph of fixed numerary pulse to compare only, will generate more successive air stream. Conclusion the article introduced a new technology in laser stiletto -- penetrable detection algorithm. The visible light that uses surveillance to come out from stiletto area radiate will realize this technology. Through measuring outcome aperture diameter sheds a specification compatibly, use this technology to be able to get more consistent alveolus.
