Using high-powered scanning system to reproduce the actual figure of workpiece to scan is the data that collects a large number of places automatically decide with essence of life justice the method of workpiece appearance. Undertaking collect and be analyticed to many dimension data is implementation the way with production process most effective control. Pass the analysis to gathering information, but circumstance of demonstrate out of tolerance can undertake adjustment the treatment quality with improving work accordingly. Collecting enough dimension information accurately to fall in order to finish effective process control in a lot of circumstances is a challenge, more such to appearance of complex curved surface. Today, measure machine the dimensional appearance that can measure workpiece automatically, through using these information and measure machine CAD system to connect, can fill fission examine whole production process. This kind is measured machine call scanning to measure machine. Scanning is to collect bit more data automatically to decide with essence of life justice the effective method of workpiece appearance. Pass advanced metric software, be like Brown&The measurement of Sharpe mainstream software PC-DMIS, but the action that utmost ground play scans, through its distinctive direct interface provided the direct link with main CAD system, the deviation that because the format is changed,avoid and arises and lack fidelity, have perfect data analysis and report function. To develop its effectiveness adequately in actual process control, introduce the basic knowledge about scanning technology everybody first. The measurement of the speed tradition that successive scanning accelerated data to collect machine match stock to touch hairdo to measure a head, the method that uses concentrated dot scanning records the data that workpiece surface nods. Below the case that orders scanning thick and fast, measure machine raise from workpiece surface measure a head, make its move gently ahead, collecting when be being nodded the next time, reduce measure. This kind of process that selects a site thick and fast is slower and cannot measure appearance effectively. Imitate measures a head to undertake successive scanning, can move along workpiece surface, send serial check the number to occupy systematic computer, avoided to nod a dot to explore the time loss that have campaign and causes, can solve afore-mentioned problems effectively. Whether to already decide according to the geometrical appearance of workpiece, measure machine the successive scanning method that uses two kinds of different types. Open loop scanning is the method that uses high speed to measure workpiece of theoretic foregone or definite already figure, its geometry quantity is by a few curves and curved surface place is formed, allow to explore surface of workpiece of bring into contact with. The motion of the machine is measuring engine work to detect by the record the place of data of work name geometry of the program is definite, pass successive scanning, the record leaves the error of actual curved surface and nominal data. Casing kind workpiece and geometrical feature, be like aperture, plane and cylinder, scanning can be finished in a few seconds, repeatability and precision are tall, describe its geometry figure thoroughly, produce the description of pair of dimension, position and appearance. Those who get bit more data to be able to assure tall repeatability get dimension, appearance and positional information. Generally speaking, the dot of generation is more, the repeatability of the result is better. Closed circuit scanning is the scanning technology of high accuracy, be opposite sealed, when the measurement of circumgyrate body work very useful, can have a pattern effectively: Include complex, special Xiaohe / or the digitlization of the aleatoric workpiece of three-dimensional curved surface, the ideal that if blade, gear, cam and rotor are,undertakes closed circuit scans chooses. Imitate scanning measures the change that the head explores workpiece to go up in curved surface direction, undertake adjustment accordingly in order to maintain the contact with workpiece surface in order to finish whole measure a process. The main factor imitate that measuring a head is accurate scanning measures a head to be able to regard small-sized, accurate auxiliary sex as 3 coordinate measure machine, its reading can serve as measure the complement of machine. In scanning process, measuring staff contacts workpiece surface from beginning to end, measured engine control system to make sure with constant exploration force undertakes touching measuring. This force undertakes deflexion of 3 axes space, sensor of high resolution electron records next displacement. The sensor that dimension data measures a head from grating and imitate ceaselessly is read to take and send software to undertake an analysis. The character when workpiece surface is incommensurate at direct contact is measured, blame contact data is collected measure a head to be able to solve this one problem (the) that be like a graph. This kind of optics measures a head to become an illuminant and electron be together like detector conformity, use normally trigonometric have the job. Illuminant gives out a bundle of accurate laser or infrared beam of light, when this smooth rapid fire arrives when workpiece surface, form the picture of the dot. Focusing of diffusing beam of light becomes photoelectricity to arrange. Any the image position that curved surface deviation reflects into the dot on array changes. A few blame contact the conformity that measure a head to have structural sex light source, form smooth plane. When this smooth plane and workpiece intersect, surface of outline of radial edge workpiece is formed. This light identifies through image sensor, change into amount to word to change image. The measurement of the distance also can undertake, be based on the appearance of surface of this light workpiece and position. Structured smooth sensor can use the XYZ coordinate with trigonometric computation many along the line at the same time. Blame contact measures head photograph to measure a scanning speed to imitate faster, but measuring workpiece feature respect to have limit. The confine of respect of workpiece feature mensurability makes the new fixed position that often needs to undertake measuring a head, reduced systematic work efficiency so. Blame contact is measured can measure a head to coordinate the work with imitate scanning, expanded thereby measure the applied domain of machine, finish include horological spare parts, plastic with pinion inside the measurement of petty and intricate work. Measure of machine overall the design is to obtain the key that high speed scans continuously to measure of machine overall the design is to obtain the key that successive scanning manipulates high speed. Need of amiable float system gets used to its machinery noumenon and control system, drive each other and develop the biggest effectiveness. For example, mechanical noumenon needs to offer the tigidity that tall repeatability needs. Controlling a system also is a crucial place, the collection that because control the system is associated mechanical noumenon, scanning,measures system of head, drive and data and computer are analysed. The change of curved surface appearance needs to identify as soon as possible, can dog accurately thereby scanning method. Control the speed that the system reacts and precision, even if the least change, decided to measure the efficiency of machine. In the meantime, need uses fast, collateral data to transmit, measure an analysis in order to assure won't lag. A lot of elements can decide a scanning is measured measure speed actually of machine, include the acceleration, oldest rate, exploration speed, exploration method (open loop or closed circuit) , and the computational ability that measures machine software. Because need much data to the measurement of appearance, in a lot of other measurement a few special scanning functions in software are not had. If filters the function allows scanning software to be able to undertake discriminating from inside the slight change of finishing face figure, be like the coarse part of blade. Filter still can reduce the change that oscillatory place causes at the same time. Another special function is the correction of the radius that measure a head, also call parallel curve calibration. In scanning application, data needs to use parallel curve function to use measuring staff radius to have transition, what obtain workpiece curved surface thereby is true express. In analysing a process, use parallel curve function to eliminate the difference between scanning dot and nominal dot, calculate thereby go out to nod the deviation between with name. Measure a result to need to be revealed the workpiece problem that identifies a likelihood in order to help easily, discover the problem is in and appropriate action is taken in the process. "In making " and " in the design " the result is compared can with all sorts of graphs the format undertakes indication, can understand quickly thereby and help the mistake that explores the place in making a process to cause. Deviation undertakes scale with chromatic code, have nominal deviation to take on scanning curved surface at the same time. (If pursue) the process designing of the spare parts and editor must be interactive, make full use of the advantage of CAD graph. Advanced scanning software package allows quantity of three-dimensional work geometry to express to be able to guide in measuring an order, extract the arithmetical vector of nominal value and curved surface automatically from CAD model. Be mixed by the area of scanning workpiece surface through clicking outline, the system can finish the scanning of pair of area and outline automatically, have a report to collect data. Most advanced scanning software includes to have packages of a series of special application software, can simplify and optimize the measurement of quantities of all sorts of intricate work geometry and analysis. If to detect wing is mixed,rotor of compressor of turbine lamina, helix, cam, straight tine is mixed the special module of inclined tine. Promote considerably as what measure efficiency, make scanning is measured machine can finish metric applying not only, still can undertake the process is controlled manufacturing at the same time. This one new system, other precision and repeatability and high speed data collect class of will metric room to be united in wedlock together with better environmental suitability. Three-dimensional scanning head is secured to be on the Z axis of the machine, but comfortable the measuring staff that matchs all sorts of differring, finish the measurement of all sorts of intricate geometry features and appearance thereby, and the new calibration that does not need to undertake measuring a head. Automatic measuring staff changes the library allows fast measuring staff to change, increased operation flexibility of the system. Scanning measures the application of machine successive scanning is measured machine is usable in a lot of circumstances, they are usable will measure, digitlize and detect all sorts of base industry with finishing product, mechanical component and various form product, included car, aerospace, project and field of agricultural and mechanical, machine tool, national defence, home appliance, computer and electron, medical treatment equipment and semiconductor. Converse project, one kind uses model the method of executive give somebody a new lease on life, hang on scanning is measured machine collect sample exterior dot. Measure what machine software place has to facilitate use converse project function, but direct from appearance CAD/CAM data generates directly in scanning data file. The data that measures the watch noodle that machine place collects can guide directly CAD workstation, the digitlization that produces figure of spare parts geometry thereby expresses. Successive scanning technology provided a kind of brand-new means for manufacturer, dimension data is used to raise production flow and whole to pledged new breakthrough is obtained on volume level in seek.
