With conventional treatment methodological photograph is compared, craft of turning of diamond of this kind of µ-LAM can shorten handling time about 50 ％ . In addition, this craft can make workpiece material recrystallization in machining a process, make workpiece anneal bate, prevent the damage of likelihood happening thereby. According to the United States director of university production research center Dr. John Patten introduces Ximixiegen, the treatment of hard fragile data is quite difficult. The turning of tool of single crystal diamond that uses a convention, grinding and abrade hard fragile data (be like carborundum, pottery and porcelain and glass) when, put in a lot of a Gordian knots, include work easy broken with generation crackle, cutting tool wears away cycle time of difference of precision of appearance of serious, treatment, treatment is long etc. Accordingly, application replaces craft newly imperative. For the µ-LAM that Ximixiegen the university develops tiny laser assists treatment craft to commercialize, postdoctoral senior deputy researcher Dr. Deepak Ravindra established Patten and this school together a tiny laser assists processing technique company. With conventional treatment methodological photograph is compared, the craft of µ-LAM diamond turning of this company can shorten handling time about 50 ％ . In addition, this craft can make workpiece material recrystallization in machining a process, make workpiece anneal bate, prevent the damage of likelihood happening thereby. Patten explanation says, µ-LAM turning craft passes focusing the laser that fiber-optic laser gives out successive pulse bundle, generation 1, the high temperature of 000 ℃ above and the high pressure that come from cutting tool of single crystal diamond to exceed 100GPa, can bate workpiece material, increase its tenacity, reduce its brittleness, make its become not easy disintegrate. With use other type cutting tool and the other laser with treatment not tall precision assists treatment craft to differ, µ-LAM craft lets stimulate beam of light to pass through transparent diamond cutting tool, and won't make its heat warm up, because be exposed when diamond cutting tool,be when air is medium, high temperature may bring about his to function drops or produce splitting decomposition. Patten points out, this craft will stimulate beam of light direct focusing has the front of point of a knife at diamond knife cut bits to form a division. Can take away heat in metal cutting of about 90 ％ cut bits to cool naturally in air normally. Also can use cooling fluid to undertake enforcing cooling to cutting bits and workpiece surface, but cooling fluid can not make laser / the thermal drop that workpiece interface is in is small. Patten says, this company already can machine ply to amount to the material layer of 50µm, but thicker without necessary cutting material. "If lathe property is enough good, adjust all link good position, OK the workpiece material with cutting thick 1mm. I do not know how much the treatment upper limit of this craft is after all. " Patten expresses, although use the spare parts of µ-LAM craft turning to go up to still have knife mark, but mark of this kind of knife already was achieved " accept rice class " . "We are OK turning gives lens side. If do not seek a part,reach dust level (0. 1nm) the surface is bright and clean degree, this craft can be competent. " this company is devoting oneself to µ-LAM system commercialize application, strive for an accessory that makes its regard diamond as lathe to undertake selling. American national science foundation also offerred bonus of 150 thousand dollar for this company, serve as what plan the first stage to SBIR to aid financially, commercialize in order to help this technology implementation. Patten estimation, to a typical hardware manufacturer, this technology can be saved every year for its 150 thousand - 500 thousand dollar. He says, "We will are opposite according to this technology the value of the user fixes a price to its. " have a test to this technology to be beyond the lab, this company is in near Pittsburgh on the lathe of diamond of Precitech 700 series of a factory installed system of a µ-LAM. Patten says, "The test makes clear as a result, its behave those who exceeded us to anticipate. Its behave those who exceeded us to anticipate.. CNC Milling
