Step S10, leading the laser pulse generated by the laser to the composite material through a preset combined lens;
it should be noted that, in this embodiment, in order to avoid the problems of wide cutting gap, deformation of cut, burr, non-finishing, slow efficiency, and the need for replacement due to the contact processing method such as cutter wheel or stamping, etc. caused by the conventional mechanical cutting method, in this embodiment, an ultrafast laser with a pulse width less than 10fs is used to perform non-contact processing on a material, and the problems of crack, edge breakage, burr, non-finishing, etc. of the cut can be effectively solved by using the characteristics of narrow pulse width and high peak value of the laser pulse, and the laser cutting gap is small, and the laser focusing spot is about 20 μm, so that the cutting quality is significantly improved.
Specifically, for example, high power laser pulses generated by a laser are ultimately directed through a combination lens toward the composite material to be cut to cut the composite material in accordance with a preset cutting algorithm.
And step S20, carrying out non-contact cutting on the composite material through the laser pulse according to a preset cutting algorithm.
In the present embodiment, the reason why the laser beam can be used as a processing means is mainly due to its optical action. The laser light mainly includes two types of photo-chemical reactions and photo-thermal effects, wherein the laser removal processing (such as cutting and punching) utilizes the photo-thermal effect of the laser. The process of laser processing materials can be divided into the following: the method comprises the following steps of material heat absorption, material heating, material surface melting, vaporization and cooling and solidification. Laser machining is essentially the interaction between the laser and the substance. The interaction of laser and substance means that when a laser beam is projected on the surface (or inside) of the substance, part of energy is reflected, part of energy is absorbed, part of energy is transmitted, light energy is absorbed in the form of vibration excitation of electrons and atoms, so that energy transfer and transmission occur, and the energy transfer and transmission cause various physical, chemical and biological effects and processes.
In particular, for example, the composite material is cut contactlessly by high-power laser pulses emitted by a laser according to a preset cutting algorithm.
Further, the composite material comprises: zirconia and brass, the zirconia being located above the brass.
It should be noted that, in this embodiment, the composite material to be cut may include: zirconia ceramics and brass, wherein the brass is an alloy consisting of copper and zinc, and has high reflectivity and very good thermal conductivity; zirconia ceramic ZrO 2 Has the characteristics of high melting point and boiling point and high hardness. In addition, as shown in fig. 3, in the composite material, the zirconia ceramic was located above the brass. As shown in fig. 4 and 5, the absorption rates of the respective metals are greatly different at different wavelengths, and the thermal conductivity and the expansion coefficient are also greatly different, and since brass has a high absorption rate at a wavelength of 532nm, a 532nm wavelength laser can be used to cut a composite material including zirconia ceramics and brass in this embodiment.
In the embodiment, the high-power laser pulse generated by the laser is finally guided to the composite material to be cut, which comprises zirconia ceramic and brass, through the combined lens, and the composite material is subjected to non-contact cutting through the high-power laser pulse emitted by the laser according to a cutting algorithm preset in the control card.
Compared with the composite material processing method in the prior art, the composite material is subjected to non-contact cutting by adopting the high-power ultrafast laser, the problems of notch deformation, burrs, unsmooth work, ceramic edge breakage and the like caused by the traditional mechanical method/common laser cutting method are effectively solved, accessories such as cutters and the like do not need to be replaced, frequent maintenance and the like are not needed, meanwhile, the laser cutting seam is small, the edge of a product after cutting is flat, no heat influence area exists, and high-efficiency material cutting is realized.
Further, based on the above-described first embodiment of the composite material cutting method of the present invention, a second embodiment of the composite material cutting method of the present invention is proposed.
In this embodiment, in the step S20, the "performing non-contact cutting on the composite material by the laser pulse according to the cutting path in the preset cutting algorithm" may include:
and step 201, performing non-contact cutting on the composite material through the laser pulse according to a cutting path in a preset cutting algorithm.
In this embodiment, the cutting paths are as shown in fig. 6, and in this embodiment, two cutting paths are used to cut the composite material. On the basis, the composite material is cut according to a cutting path in a preset cutting algorithm, so that the cut composite material is consistent with the cutting path. In this example, as shown in fig. 7, the cut composite material was examined by VHX-5000, and as shown in fig. 8 and fig. 9, the cut composite material had no thermal effect, no burr and black cross section, and no broken edge of the ceramic. Therefore, the non-contact cutting for the composite material is realized in the embodiment, and the quality of the cut workpiece is improved.
Further, in step S10, the step of directing the laser pulse generated by the laser to the composite material through the predetermined combined lens may include:
step S101, guiding laser pulses generated by a laser to the composite material through the beam expander, the galvanometer and the field lens, wherein the laser comprises: a green picosecond laser.
It should be noted that, in this embodiment, as shown in fig. 10, the cutting system finally guides the laser pulse generated by the laser to the composite material through the beam expander, the galvanometer, and the field lens, so as to cut the composite material through the high-energy and high-power laser pulse, and in this embodiment, the composite material may be placed above the movable processing platform for cutting.
Specifically, for example, the cutting system is specified in fig. 11, a beam expander is used to change the beam diameter and the divergence angle of the laser pulse, a galvanometer is used to control the deflection of the laser pulse in the X-Y plane, and a field lens is used to focus the laser pulse. In addition, in the embodiment, the laser pulse generated by the green picosecond laser can be used for cutting the composite material, and the parameters such as power, frequency, speed, pulse train and the like are limited, wherein the laser power can be set to 10-25w, the laser frequency can be set to 50-300KHz, the speed can be set to 30-500mm/s, and the pulse train Burst can be set to 1-3. In this embodiment, the parameters of the laser are not specifically limited, and the parameters can be adjusted according to the actual cutting situation.
Further, before the step S20, "performing non-contact cutting on the composite material by the laser pulse according to the preset cutting algorithm", the method further includes:
and step S30, controlling the galvanometer through a control card according to a preset cutting algorithm so as to guide laser pulses to the composite material according to the preset cutting algorithm based on the galvanometer.
The preset cutting algorithm comprising the cutting path is pre-imported into application software, then a cutting instruction is sent to the control card through the application software, and the control card drives the galvanometer optical scanning head, so that the deflection of the laser pulse is controlled on an X-Y plane, and the laser pulse can perform non-contact cutting on the composite material according to the cutting path contained in the preset cutting algorithm.
Further, before the step S10, "directing the laser pulse generated by the laser to the composite material through the predetermined combined lens", the method further includes:
and step S40, supplying power to the laser through a laser power supply, and dissipating heat and cooling the laser through cooling water.
In order to avoid the over-high temperature of the laser during working, the water circulation cooling is needed to be carried out on the laser generator of the laser device, and the service temperature of the laser generator is controlled, so that the laser generator can normally work for a long time, and the normal work of the laser generator is prevented from being influenced by the over-high temperature.
In this embodiment, the laser pulses generated by the laser are sequentially directed to the composite material through the beam expander, the galvanometer, and the field lens. The field lens is correspondingly adjusted according to a cutting path in a preset cutting algorithm, the preset cutting algorithm comprising the cutting path is pre-imported into application software, then a cutting instruction is sent to a control card through the application software, and the control card drives an optical scanning head of a galvanometer so as to control the deflection of laser pulses on an X-Y plane, so that the cut composite material is consistent with the cutting path.
