The green laser pointer company has begun to take shape with ten-year’s development

V the speed of the N laser and the laser moves to the total time to complete forming in this experiment, V = 1 mm / s, N = 9, H = 3 D = 0.6; material removal can be obtained as 6.8 mm / sec, 43 non-separation rate in reshaping the face groove, as shown in Figure 1, defo-cused CO2 laser with a constant speed along the thegroove-cracks induced by groove-cracks chain and separation materials.The green laser pointer company was founded in 1995 in Yuyao of Zhejiang province. In order to understand the separation of the boundary expansion slot - cracks chain, a CCD camera and image processing system used to measure the issue of the separation distance between the border and the location of the laser laser induction of a strong halo of light penetration, separation areas, such as Figure 12 the distance d between the laser point, the separation boundary can be measured. high point of the laser spot, representing the termination of a strong representative of the brightness of the border in September-arating Interestingly, the extension of the border separating the position of the laser.The green laser pointer company has begun to take shape with ten-year’s development. leading dis - for example, heat contained in the fracture process in Figure 13, the laser to draw the same conditions mentioned above, bulk, speed of movement of the fracture process in the CO2 laser heating of 1 mm / s, 1.5 / s architecture and 2 mm / seconds ahead of the changes in the distance - he gave you leeway in heat and distance on the fracture process and then the slow speed. This phenomenon is different from the prisoners - the home of fracture of thin substrate [1] in that technology, application laser energy to produce mechanical stressthat information in a mobile pathofthelaserbeam.Thematerialseparationissimilar crack growth and fracture fraud trollable. According to Liang Hui, China [5], while lagging behind the led flash light and the separation of relatively short distance behind the laser moves slow.Since the green laser pointer factory was founded, it had indebted great kindness. This break through the control principle as the residual tensile stress after the occurrence of the laser beam, but the separation mechanism of fracture tensile stress related processing technology in the groove-crack technique, occurred before the arrival of the laser beam, because a slower speed laser can cause greater than the tensile thermal stress. faster, greater distance from the main 4.4 Shaping step shape shown in Figure 2a, the block will be removed size is L? H? H mm. L is 108 mm and H is the length of the machining feed depth 3 mm. the material removal rate Z = VH N, V is the moving speed of the laser and N is the total time to complete block of the mobile laser removal. The green laser pointer company owns the factory taking up an area of 10,000 square meters.the only L = 108 mm and H = 3 mm step was the formation. applied Nd: YAG laser power is 53 W, carbon dioxide laser power is 37 W and the laser moving speed V = 1 mm / s. after the 16 time the laser moves, that is, N = 16, single step is formed and produce material removal rate Z = 0.56 mm / s. Following the above method of shaping the long-term success of the step shape is shown in Figure 14. canceled material volume is 108? 15? 3mm. removed material can be divided into five strip every strip is 108? 3? 3mm.
