To high speed Che Xi and imperceptible treatment develop

Platoon and energy-saving tidal current are reduced in CO2 in, LED (glow diode) illume application gets be drivinged quickly. the mould treatment that in reaching LED lens process to making LED, uses, need undertakes is based on the imperceptible treatment of cutting. In the internal diameter cutting of component of bearing of hard disk fluid, and the imperceptible liquid of medical treatment domain sheds the imperceptible treatment such as treatment in exercise, cutting and accept rice embossing, laser beam machining reachs discharge treatment to wait for the position with be had coequal and significant. On the technology, already can realize Nm at present (accept rice) the treatment precision of level. This is the technology in respect of mill of high speed car accumulates the positive result that gets on the foundation. The high accuracy of 　 of mill of high speed car at imperceptible treatment changes applicable and the requirement such as high production efficiency can rotate with the high speed of above of 100 thousand Rpm trail establishs milling cutter to undertake cutting. Will explain its principle below. Want to raise treatment precision, must make cutting tool is cut very shallowly. If do not add other measure, be about to pay handling time to follow price of treatment length prolate. Accordingly, rotate through high speed below the condition that keeps fixed in every blade approach undertake high speed feed, can make the cutting cubage of unit time gets addition. And, high speed cutting returns hopeful to come true to be decreased considerably thin cut bits, drop the good point of cutting obstruction. Such, machine what place of the cutting tool in the process arises to curve obstruction to also can decrease, the trail cutting tool that makes tigidity low thereby also can achieve favorable treatment result. Return what hopeful restrains cutting tool to wear away additionally. From the point of these circumstances, how to come true effectively be based on high speed to rotate, low volume cuts the high speed cutting that reachs high speed feed, very important to small treatment. Already had experimental result a case of a physically strong patient running a high fever or suffering from such disorders as stasis of blood at present this one principle. In freeboard fast crankshaft of turbine of small-sized air bearing (ABSF-1600: NAKANISHI is made) on use exceed hard coating radius to establish milling cutter, in approach and cutting length same condition falls, have planar treatment with 140 thousand Rpm with 100 thousand Rpm respectively, the with standard set rotate speed rotate speed deviation that the attempt determined to machine bear to bring about. Handle via undee signal next, the average cutting obstruction when reaching rotate speed is reduced and analytic result. Data shows, 140 thousand Rpm and photograph of 100 thousand Rpm are compared, cutting obstruction was reduced 9.

6 ％ . That is to say, high speed rotates make cutting bear tends apparently reduce, beneficial effect had in the treatment that uses trail cutting tool. The cutting tool of mill of high speed car of fine treatment of comfortable Yu Wei has not been designed, existing device and system realize afore-mentioned operation very hard. Must want pair of cutting tool, machine tool and control means to undertake respectively brand-new design. Look above all from cutting tool, want to achieve second micron level exceed accurate cutting precision, cutting tool wear limit must be controlled it is under several μ M (the face that retreat a knife wears away rub bad news width) . In this on one hand, the research achievement of mill of high speed car provided available data. For instance, when contrary milling cutter undertakes small way is designed, to raise cutting tool tigidity, must want utmost ground to ensure sectional area. Accordingly, the groove between cutting edge is more shallow, horn is worth to lose before (the pitch face of cutting edge compares right angle more undertake pitch to feed direction a side) cutting edge appearance is more advantageous. The cutting edge of negative worth angle of its point of a knife with obtuse angle (be more than 90 ° ) common, make sufficient cutting process capability is had when mill of high speed car. In the small way design that establishs milling cutter, cutting tool material also is having very main effect. The cutting treatment of imperceptible appearance is very difficult have precision work again after cutting, had better be to use department of point of a knife invariant " nondestructive cutting tool " the one-time finish machining that finish. Use the data such as the CBN agglomeration system that exceeds hard alloy to have wear-resisting caustic sex more than coating and diamond agglomeration body normally at this moment. Use what the graph shows 1 times still is use when exceeding hard alloy, bead diameter is those who count 100 Nm class to exceed exceed particle child alloy. Graph 1 exceed particle of He Chaochao of small particle alloy child alloy but these cutting tool material because hardness is tall and undertake cutting tool shapes hard. Find out high accuracy and efficient cutting tool shapes the method will be henceforth the task that faces. To this, also can consider to pass abrade undertake cutting tool shapes, graph 2 be grind shaping diameter through grinding the square of 30 μ M establishs milling cutter, ensure for utmost ground sectional area, used will columnar expurgation the cutting edge appearance of one part. Graph 2 exceed accurate and imperceptible cutting to establish milling cutter with radius of CBN agglomeration body (30 μ M) (day takes a tool) Nextpage 　 pursues 3 medium cutting tool are a planar cutting with establish milling cutter, can come true have evenness of second micron class to spend the treatment face with fineness degree. The control of treatment face fineness degree that will be cut to cut material is imagined to arrive under 1 μ M not only when development, and still considered in precision and efficiency respect cutting treatment wants to compare abrade treatment more advantageous. Graph 4 in the product estimation that the diameter is 10 μ M is the town with the at present smallest size carry out establishs milling cutter. Graph 3 exceed accurate and planar cutting to establish milling cutter with radius of CB agglomeration body (day takes a tool) graph the city carry out with 4 the smallest size establishs milling cutter (day takes a tool) axial shift is controlled to be in imperceptible treatment directly below the case that having interpolation, original machine tool controls a method to already can't satisfy requirement. The existing CNC program that creates by CAM according to three-dimensional model data already reached the limit. Use at cutting to give the cutting tool contrail that appoints appearance, it is into small line segment according to cent up to is like data to output mostly at present, because this increases the word that machines precision to be able to increase data bulk, often want to spend a large number of time when outputting the CNC program that creates by CAM. And, numerical control device also needs time to unscramble CNC program. Such with respect to block up will come true through developing the character of machining center adequately more high speed, more the cutting of high accuracy works. Among them, when using CNC program to undertake the cutting of nicety and small figure is machined exceeding especially, still need to use more tiny small line segment and linear interpolation data, can appear in precision and efficiency respect more problem. Accordingly, a kind not by NC code and the system that dictates to shift of athletic controller take-off directly (weigh DirectMotion below) was developed (sanded Dick Sodick is announced) . Can be in so treatment precision and treatment efficiency improve in exceeding accurate and imperceptible cutting. Graph of the 5 processes that revealed DirectMotion to give out cutting to dictate and ordinary control means different. DirectMotion can be in CNC control system inside buy CAM function, because this requires an input only,CAD data can carry out optimal cutting. Graph what 5 common CNC control means and direct way is different (sanded Dick) after the example that 　 uses this to control a system to undertake cutting will be in, undertake introductory, already confirmed time of cutting precision, cutting all compares original CNC to control means to have at present nevertheless rise considerably. Direct card is close, with 　 of linear and motor drive besides, be in even machine tool (machining center) on take the way to deal with a situation, carry feed rate when processing imperceptible form for instance, will be opposite when cutting of point of a knife bump control to arrive the smallest be restricted, etc. Current, the experimental model that Japanese manage turns institute and sanded Dick to be developed jointly is undertaking trying (graph 6) . This experiment type can undertake small way establishs milling cutter cutting, main shaft adopts air turbine drive, rotate speed can be achieved minutely 200 thousand turn, brace up place precision and heat to be out of shape control is in 0.

Less than of 3 μ M. To raise point of a knife brace up place precision, used the main shaft that is based on shrinkage fitting to block close way directly. The acceleration character respect of system of linear and motor drive, it is inside XY plane 1.

5G, z axis is 1G, can realize nimble feed operation. Graph 6 exceed accurate and imperceptible cutting to use model of machining center trial-produce (manage chemistry institute and sanded Dick) Nextpage 　 after Shadikeli has cutting test with this experiment type, exceed imperceptible and accurate machining center at was being rolled out in December 2005 according to experimental result (graph 7) . Use minutely the 120 thousand low heat that turn is out of shape motor of linear of main shaft, complete axis, two axes are opposite drive feed orgnaization, and the new design such as device of direct control CNC, compare with original machining center photograph, what can obtain 10 times above is efficient. And, those who return hopeful implementation to have precision of thickness of appearance of stage of odd accept rice and appearance precision is new-style exceed cutting of accurate high speed. Graph 7 exceed accurate and imperceptible appearance to use machining center economic model (sanded Dick) 　 the further support that will go up to be machined imperceptibly to exceeding as the technology henceforth, the tiny cutting tool that uses the flesh likely still to be less than soon undertakes cutting, will inspect very hard through eye at the appointed time will affirm cutting in the begining be close to a movement. The operation of the machine tool is a center with order injunction, want inevitably to use the method such as imitate, sensor to come to those who prevent cutting tool bump. Need not abrade can realize technology of lens face above to develop achievement to had gotten reflecting in exceeding imperceptible nicety to machine example. Because matter to the most most advanced new product development directly, open example is accordingly very few, if the graph is shown 8 times,do not pass, in respect of tall hardness steel, had appeared to establish milling cutter to be opposite with agglomeration body the example that 20 μ M and the corner R appearance of 13 μ M have cutting. The cutting of tiny R appearance, its key depends on wanting those who control knife horn share to wear away, this one appearance is before accepted come true hard through cutting. The corner ministry of M of μ of graph 8 R13, R22 μ M is machined (day enters tool and sanded Dick) 　 pursues 9 it is tens of ～ Channami the planar cutting example of class. When this technology is cut with exceeding nicety to be cut imperceptibly, ensure material is planar precision be developed for the purpose and become. Its meaning shows in Yukeshi need not finish machining can the precision that cutting gives the appearance such as optical lens.
