Although the utility of itself of nuclear power microscope is small measure,becoming is not treatment, but it and workbench of closed circuit of the type that suppress report are united in wedlock, can overcome when be being used at machining thirdly the limitation of journey limits of the axis and resolution. According to machinist of university of collect Lai accept getting stuck south the United States Cheng fastens accept rice structure and Li Xiaodong of dependability lab chief (transliteration) professor introduction, people thinks normally, the spare parts of measure of preparation accept rice needs to use a kind " bottom-up (Bottom-up) " technique, pass namely add material -- it is an atomic ground adds an atom likely -- will form a part. Dr. Li says, "People tries to abandon traditional ' top-down (Top-down) ' technique, this kind of method is to pass purify material to come device of measure of preparation accept rice and spare parts. " design plant of rice of a kind of accept to prove to use CAD software, use traditional machining technology to machine the feasibility of spare parts of cashier rice measure and form appearance next, dr. Li and the researcher that come from institute of project of Electromechanical of Chinese Harbin Institute of Technology together, press microscope of workbench of nicety of class of rice of accept of electric type closed circuit and an atom force (AFM) is compositive arrive one case. Study according to Harbin Institute of Technology Professor Dong Shen introduces one of group controller, paper authors about machining of accept rice measure, although the utility of itself of nuclear power microscope is small measure,becoming is not treatment, but it and workbench of closed circuit of the type that suppress report are united in wedlock, can overcome when be being used at machining thirdly the limitation of journey limits of the axis and resolution. Professor Dong says, "Because need feedback, because this kind of system calls closed circuit system, it can move accurately from a position with accept rice resolution another position. " he points out, this workbench is made by company of German PI(Physik Instrumente) , nuclear power microscope is the product of company of American Veeco instrument. test and verify the process capability of accurate workbench and this nuclear power microscope, researcher uses machining method to be Ra9 in exterior surface roughness.

Of 8nm burnish aluminous dish of appearance on treatment gave figure of face of a three-dimensional person, its frame dimension is 20µm × 20µm, concave and convex height is 120nm. The installation of point of a knife of single crystal diamond that they are radius of a circular arc 30nm is on the stainless steel cantilever of nuclear power microscope, imitate treatment of conventional numerical control machine tool next, have score to workpiece surface, make its produce plasticity to be out of shape. This system besides can process metallic data, still can machine polymeric with semiconductor material. Does this craft have: of mode of purify of 3 kinds of material? Glue of J of Shang Wen of Yin of ㄈ of be good at ⑿ of J of  let down with a rope dash forward benzene of cough of core of be good at Q of J of Qia of that Xing of envy of travel of Lou abb Shan masts Qin carries J of つ of commonplace of  of  Chen Fan to wring agitate of Lu of situation of  of the  that protect  take along sth to sb of  of  of boundless and indistinct of Yong of crisp plaque  . When undertaking cutting with the feed of 200nm, can machine the groove with a consistent measure, although diamond point of a knife always is not the cutting position of 50nm and 100nm at feed. The form appearance measure that in Z axis direction treatment gives is controallable inside accept rice limits, and the form appearance measure that gives in X axis and treatment of Y axis direction is in 0.

Between 5-100µm. Dr. Li expresses, treatment appearance the surface needs 10 minutes about, and for the treatment method that this has commercial application value to a kind, time is apparent too long. His complement says, this research group is trying to realize large quantities of quantities to machine. For this, can you use: of two kinds of methods? Emperor steals bank of Xi Cang of Piao of  of triangular bream of show off post  of account of soft-shelled turtle egret Guo   goes straight towards commonplace ざ ? of W of post Qu of ひ of commonplace of Qiang of  of regret of Yu ぜ  namely moulage) , use the accept rice inscription rubbing that has large quantities of amounts to machine. This research group returns plan general " top-down " treatment and " bottom-up " treatment (if be in line of rice of accept be growthed by treatment surface deposit) union rises, in order to make full use of the advantage of these two kinds of methods, increase preparation to give the chance of device of active accept rice and accept rice structure further. Dr. Li says, "Come for years, in domain of accept rice preparation, people always says ' we cannot depend on a kind of method only, we need to rise all sorts of method union, ' we are making this kind of idea dreams to come true. ' we are making this kind of idea dreams to come true.. CNC Milling CNC Machining
