Description of the invention (3) The heating temperature of the material is reduced by increasing the cutting temperature of the cutting tool 2 and the heating of the cutting tool 2 is softened to adjust the laser parameters to determine: cutting ::: cutting Formula, it will be difficult to take into account both cutting efficiency = cutter, and to study and consider where appropriate. [Inventive content of the surface] The main purpose of the present invention is to provide an emperor Λ 77 with F Jin emperor's body + -5 η field shot auxiliary cutting.重量 化 材 #, the cutting tool feeds Cheshbo, cooling the sprayer, sprays the low-temperature fluid of the cooling sprayer on: 'to cool the high temperature generated by the knife tip, and then make the temperature range' by this' namely The laser beam can be used to make cutting :: Warm heating softens the fork state and at the same time ensure the cutting tool: In addition to effectively improving the cutting efficiency and surface accuracy, it also has the dual benefit of service life. A secondary object of the present invention is to provide a laser assisted cutting. The cutting tool can be provided with a cooling liquid inside the handle of the cutting tool. It is for a moment. ^ /;,! Degree, phase rate , Because of the range requirement, so it is still in the first one ... "M Shi You V, mouth 7 shape follows the king | but the fluid circulates inside the cutting tool to reduce the temperature of the blade tip due to friction heat, and thus make The temperature of the tip is maintained to ensure the rigidity of the cutting tool, to effectively improve the accuracy of the female face, and to simultaneously double the life of the tool ^ [Embodiment] j It is better to make your reviewing committee take the invention one step further. The embodiment and the drawings are detailed as follows: The cutting tool is installed on the laser beam holder to maintain a high rigidity, and an extended knife device is provided. Its path will cut cold and warm and the temperature range efficiency. And the explanation, here are 200520915 V. Description of the invention (4)… Please refer to Figures 3 and 4, as shown in Figures 3 and 4, the cutting tool is installed on the chuck of the machine tool, and the cutting part 8 (such as ceramic) is set 1 On the 0, a laser head 1 1 system is installed on the tool 9 installed on the side Side of the cutting tool 9 and place the laser cutting tool holder 10 on the front of the cutting edge (ie, heating zone E). Adjust the focus to the cutting tool 9 chip sprayer 1 2, which sprays with high pressure ^ The tool holder 1 〇 is equipped with all the chips to prevent the chips from being blocked by the laser beam machine a (such as gas or liquid). One can be sprayed such as refrigerated gas or liquid inert. Please refer to Figures 5 and 6, when the cooling spray of the low-temperature fluid is activated, the chip ejector 12 and the laser 2 are started, and when cutting is started, it is directly in front of the knife edge 'and made there. The material laser beam irradiates the cutting tool 9 directly to the high-temperature softening material 2 ^, material F. Due to the high-temperature cutting at the focal point and the high-speed cutting friction heat during this process, heat will be transmitted to the cutting tool 9 In order to prevent the cutting tool 9 from rising, the cutting tool 9 gradually becomes the cutting tool 9 and the cutting tool 9 is damaged in advance. The present invention is used to cut the high-cut situation. Sprayer i 5 continuously sprays cutting tool two 9 warm fluid of cutting material (Such as frozen gas or liquid j, the position is lowered), to directly cool the cutting edge of cutting tool 9 ^ ^ gas and other low-temperature fluidity is maintained within the appropriate temperature range (not exceeding 1 4 7 ft to warm the cutting edge of the tool The rigidity of 9; In addition, because the cooling sprayer 丄 1 is used to ensure the cutting fluid, when spraying high-temperature low-temperature fluid, it is also ^ spraying low-temperature chips and cooling cutting tools, and the chip sprayer can also be used for spraying at the same time. In addition to cutting, a chip sprayer is installed; please refer to Figure 7, for cutting, which can save 200520915 V. Description of the invention (5) Insert the workpiece 8 ^ The south temperature softening material F in front of the knife edge is directly cut and peeled 5 because The high-temperature softening material F has been instantaneously heated and softened, so that cutting resistance can be greatly reduced, so that the cutting tool 9 can improve cutting speed and cutting accuracy. Please refer to FIG. 8. In addition, in order to avoid the uncertainty of the cooling effect caused by other factors during the cooling process of the cutting tool 9, the present invention can also be equipped with a digital thermometer 1 3 in the handle of the cutting tool 9. Digital thermometer 1 3 is used to monitor the temperature of the tool tip and feedback immediately. The system controller 1 4 will automatically adjust the laser parameters through the system controller 14 if the tool cannot be cooled to a proper temperature with a low-temperature fluid. To change the heating temperature of the material by changing the laser to keep the tip temperature within the proper temperature range ® to ensure the service life of the cutting tool 9 and to help provide a second line of defense for tool cooling; see Figure 9 This is another embodiment of the present invention. The workpiece 8 is installed on the chuck of the machine tool, the cutting tool 9 is installed on the side tool holder 10, and a laser head 11 is installed on the tool. On the base 10, the laser beam is adjusted to focus directly in front of the cutting edge of the cutting tool 9, and a chip ejector 12 is installed on the tool base 10, which sprays fluid at high pressure to remove chips. Prevent chips from being covered by The beam is radiated, and a coolant circulation flow path 16 is provided inside the cutting tool 9, and the coolant circulation flow path 16 is connected to a freezer 19 at its inlet and outlet 17 and 18, respectively; Fig. 10, when the workpiece 8 starts cutting, the chip ejector-1 2 and the laser head 1 1 are activated, so that the laser beam is irradiated directly in front of the knife edge to soften the material 'at the tip of the cutting tool 9 When the temperature in the south of the laser focus and the frictional heat between the cutting tool 9 and the workpiece 8 gradually increase the temperature, that is, 200520915 V. Description of the invention (6) The coolant circulation flow path 16 inside the cutting tool 9 can be used. The cutting tool 9 is indirectly cooled with a low-temperature fluid, so that the temperature of the cutting edge is maintained within a proper temperature range to ensure the rigidity of the cutting tool 9 and thereby effectively extend the service life of the cutting tool 9. Please refer to FIG. 11. In order to avoid the uncertainty of the cooling effect caused by other factors during the cooling process of the cutting tool 9 during the cooling process, a digital thermometer 1 may be additionally installed in the handle of the cutting tool 9. 3, using a digital thermometer 1 3 as an online monitoring tool tip temperature, and immediately feedback to the system controller 14, if the tool can not be cooled to a suitable temperature with a low temperature fluid, the system controller 14 automatically performs laser parameters Control to change the heating temperature of the laser to the material, keep the tip temperature within a suitable temperature range, to ensure the service life of the cutting tool 9, and then provide a second line of defense for tool cooling. To sum up, the present invention is a design with deep practicality and advancement. However, the same products and publications have not been disclosed, so that it meets the requirements for the patent application for invention, and applies according to law.
