After laser focusing, luminous energy is converted into heat energy, almost can melt, gasify any material. The hard brittle materials such as such as resistance to heat seal is ceramic, diamond stone, diamond can be processed; Laser facula size Jiao can gather micron order, and output can regulate, and therefore may be used to precise fine processing; Processing used tool is laser beam, is noncontact processing, so not having obvious mechanical force, it does not have tool loss problem. Process velocity is fast, and heat affected area is little, it is easy to realize course of processing automatization; With electron beam process etc. comparatively, laser processing device is fairly simple, it is not required that complicated vacuum extractor; Laser Processing is the hot-working of a kind of instantaneous, local melting, gasification, influence factor is a lot, therefore, precise and tiny man-hour, precision are added, especially repeatable accuracy and surface roughness not easily ensure, repetition test must be carried out, find rational parameter, can be only achieved the splashes such as the metal gas produced in certain processing request processing and Mars, taking away it is noted that ventilate, operator should wear protective glasses.
This laser machining centre operation principle is: utilize high energy laser beam, instant melting or vaporization workpiece respective regions remove material, when laser facula size is certain, the ability regularity of distribution is certain, irradiation time is certain, laser action point is certain with part finished surface distance, and workpiece material one timing, the quantity of material that high energy laser beam unit pulse or unit interval remove also determines that. The principle of selective laser sintering molding in our analogy rapid shaping, during selective laser sintering molding, being by the three-dimensional CAD model of part, hierarchy slicing (is automatically performed by computer) and then successively scans sintering slicing profile with laser, forms final part. On laser machining centre, being cut into slices by the three-dimensional CAD model of part blank and part simultaneously, then deduct part respective slice profile with the respective slice profile of blank, remaining area seeks to the material removed. Then move by certain scan mode in the profile removing material with high energy laser beam, so successively remove material and ultimately form fabricated part.
Experimental example: as shown in Figure 4, it is necessary to the blank of processing part is one block of rectangular raw material. Assuming that round hole axial is z-axis direction, to this part obviously to be perpendicular to the plane in z-axis direction, within the scope of part, arbitrary section profile is the same, then dash area every part is sought to the material removed. When each parameter is certain, as moved laser beam with certain scanning speed, it removes the words that the degree of depth is h (such as 0.05mm) of material, then just can arrange section cad software, highly cut into slices every h.Then control computer and successively scan blank removal material according to slice of data, finally give corresponding part. Certainly this is a prismatic special case, just the same for variable cross-section out process, and simply slice thickness at this time will directly affect Accuracy of finish and the surface quality of part. Cutting into slices in theory more thin, the part processed is more accurate, certainly at this moment to regulate laser parameter accordingly so that the degree of depth and the slice depth of removing material adapt.
Scanning pattern can have various ways according to cross section, and the method for its optimization can use for reference the scanning pattern optimized algorithm of the laser facula in laser sintering and moulding. Scanning pattern is illustrated as shown in Figure 5.
The above is only preferred implementation of the present utility model; it is not limited to this utility model; should be understood that; for those skilled in the art; under the premise without departing from this utility model know-why; can also making some improvement and modification, these improve and modification also should be regarded as protection domain of the present utility model.
