It is advisable to use quick puncture instead of ordinary puncture.However, before setting the quick puncture, it is required to adjust the length of the cut line properly (Quick puncture holes have large aperture and rough surface, requiring longer lead-in lines to correct cutting quality).Because of the process needs, the parts are usually reserved in the nesting area.

It is suitable for single trial production and small batch production, which can quickly satisfy the customers’ pursuit of personalized products.In the thick plate processing, laser cutting processing advantages are more obvious. Laser engineers and technicians are often required to calculate a laser’s power density to determine whether a beam would damage an optic or sensor or for other various applications. Just because I want to know the max efficiency for the Laser Drill, I need to use a formula to know the efficiency at it's current altitude. Then, using the procedures specified in Method 204E, one must If RC(w) is the measured RIN at plane C (which includes Poisson RIN), then the laser RIN is given by the ray is called "s" ray. methods and CE formula for each protocol are listed in Table 2-1. Figure 3b shows that the cutting head is not lifted after optimization and setting in the programming software. External-cavity semiconductor lasers have a semiconductor active medium in a larger cavity. Each pulse of light produces only small particles of spray, which is gradually deepened, so it takes a few seconds for the thick plate to perforate.The advantage is that the piercing quality is high and the cutting quality is guaranteed.The disadvantage is that it takes a long time and requires some debugging experience, and the puncture time increases with the thickness of the plate.The material formed a pit in the center after continuous laser irradiation.The disadvantage is big thorn perforation. Liver Efficiency Formula helps support liver function by encouraging healthy mitochondrial energy output in liver cells and by helping to safeguard your liver against oxidative stress by encouraging the production of the body’s two most potent antioxidant compounds: glutathione and super oxide dismutase, or SOD. Both value can be looked up in handbooks. 2.3 Building Enclosure Building enclosure protocols involve using the building that houses the process as the enclosure. The absorption coefficient, α, is related to the extinction coefficient, k, by the following formula: where λ is the wavelength. Note: this box searches only for keywords in the titles of encyclopedia articles. I am interested in how SEchanges at temperatures above room temperature, which I will define here as 25 °C. © RP Photonics Consulting GmbH      All rights reserved worldwide So reflection and absorption of laser The significant difference between LED and LASER lies in the working principle. Electrons are more likely to interact with the structure rather For example, the spacing between the parts or the distance of the outer contour of the plate.Proper reduction of spacing or the use of a shared edge can be used to save the plate.In order to explain how to shorten the laser cutting time and improve the utilization rate of the plate, this blog post summarized 4 methods including adopt shared edge cutting, optimize the sheet material, reduce the cutting head lifting motion, and choose the punching method reasonably.Through practical verification, to utilize the above methods comprehensively can effectively improve work efficiency, reduce waste and improve economic benefits.I’m thankful that you mentioned in your article how it is important to optimize the sheet material present in order to get the cleanest cut possible. A laser works on the principle of stimulated emission and LED works on the principle of Electro-luminance.

Laser processing has the advantages of high machining precision, good surface quality, low processing noise and small vibration of equipment.Laser cutting machine adopts non-contact machining principle.Compared with ordinary multi-station punch processing, no special mold is needed, so its processing scope and conditions are limited.According to the requirements of product design, the complex shape can be cut at will. If the position setting is not good, it will affect the contour, thus affecting the cutting quality.For thick plate cutting, especially large contour cutting, such as carbon steel plate above 4mm with a diameter of more than 10mm. I have drive current versus optical power and temperatur… the fact that it's 0 in the equation seems to indicate one of the two but I'm not sure.New comments cannot be posted and votes cannot be castPress J to jump to the feed. of material.

the angle of incidence and plane of polarization. (figure 2) The distance is the diameter of the laser spot.According to statistics, the actual cutting path can be reduced by 30%, and the material utilization rate is increased by 8% if adopt shared edge cutting.Usually, the machine will lift up to a certain height after cutting an outline, and then move to the cutting position of the next contour for piercing and cutting.The purpose of this is to prevent collides with the cut piece when the cutting head from moving from the current profile to the next cutting profile.However, once the cutting path of the cutting head is optimized, or the contour of micro-connection is used, the lifting motion of the cutting head can be removed to improve the cutting efficiency of the laser cutter.FIG. I have spent much of my summer dealing with issues related to the high temperature characteristics of lasers.
