Fast and accurate laser measures a technology

(API) manufacturing 5 dimension or system of 6 dimension laser, all sorts of distinctive performance that show contemporary laser to measure a system to be able to be achieved. The laser that designs by this company surveys a system, it is with the 5 dimension of accurate interferometer or 6 dimension sensor are a foundation, use at measuring CNC machine tool and coordinate to measure the fixed position precision of machine. The laser light beam that interferometer sends enters sensor, divide next divide beam of light for 3. Beam of light of the first cent will return illuminant, in order to undertake linear displacement is measured; Beam of light of the 2nd cent enters two-way sensor, in order to measure level and perpendicular way do not spend an error continuously; Beam of light of the 3rd cent adopts an optical structure, measure deflexion and admire Fu. By compositive differential laser system measures rotational angular displacement. The user can be in a reference axis of the machine tool (like X axis) on install 6 dimension laser, can measure the error of 6 all reference axis at the same time. The Mike Glossinger of API says, "If you are,measure on general accuracy machine tool, criterion Y axis should become 90 ° with X axis. Had located laser, if fixed position is on X axis, insert a 5 prism, let beam of light fold a turn to go up to Y axis, fold as it happens of degree of curvature to be 90 degrees. " laser keeps dormant, only 6 dimension sensor moves to undertake metrical to Y axis. Use what obtain from X and Y axis not to spend data continuously, the patent software that measures measuring implement to go up can decide every reference axis is checking the trend in plane to be calculated its verticality. Every axis on 3 axes machine tool has 6 likely position error: Error of axial shift fixed position; Be in perpendicular the linearity sum of errors on the axial direction of mobile axis 3 angle error (rotational, a simple move or action, deflexion) . In addition, the square that 3 mutual and perpendicular plane make the machine tool spends an error. Be installed through 3 and measure an operation 3 times, the system can decide sum of errors of on the machine tool 17 axes two square spend an error. The rotational sensor with existing API cannot measure the roll of vertical axis. In be installed 5 times and be operated, the system can decide 21 likelihood 20 in the error. Glossinger says, "We can be being made an appointment with 4 ～ undertake complete analysis to a machine tool inside 5 hours. " he believes, by what resemble API 5 or the data that all of 6 hold together collects, offer the opportunity that reachs new precision level for machine tool manufactory. "Final, the business that the business that machine tool manufactory should do in compensation respect should do side of purer than be in only linearity wants much. Be in current, they try to use very good mechanical method to make a system, but those who leave them is fitly cannot amendatory small error. Now, pass certain compensation, we can make the machine tool better (saying exactly is performance/price ratio) . " in more general situation, by Mitutoyo (MIT) Corp.

Manufacturing laser micrometer confirmed the speed of the measurement technique of laser and precision in successive process. These systems aim laser light beam a gyral illuminator. When illuminator rotation, stimulate beam of light to shoot to unit of a photoelectricity. This unit sendout measures size to produce change into direct ratio ground along with the beam of light that reachs its to go up, make the system can be located in the diameter of the workpiece between unit and laser certainly. Commonly used MTI laser micrometer is like Series544, it is the workpiece of 1 ～ 51mm to the diameter, its precision is ± about 0.

0030mm, repeat precision to be ± about 0.

00013mm. The Dale Schauer of MTI says, "A few manufactories use He, Ne canal regards laser as illuminant, but we use diode however, because its service life is longer. Some He, Ne is in charge of its service life to exceed 600h, but use laser diode, occasionally, its life exceeds 7000h unexpectedly. " laser micrometer often tries to use as a component of larger system. Schauer observes, "Having half above laser is to be hidden in the process control part of certain instructor instrument. " current laser micrometer still has buildup function to spend. "Compare with old plant phase, they have more process designing to control ability and faster output capacity. " online when measuring, the cleanness that the user still wants to notice a spare parts is spent and surface roughness. Schauer warning says: "One oily or its ply may amount to the film of water radical cooling fluid very millimeter. In addition, you get even some kind of influence of exterior surface roughness. Certain resolution has 0 only in these device.

5 μ M. In addition, of the spare parts search very crucial. Any minim tilt to will cause wrong reading. The thing that any on the spare parts sticking all may be affected measure an outcome. " he does not agree with laser measure measure than mechanical or Electromechanical type want expensive point of view. "If respecting uses mechanical system to measure the silk between the model that dial silk to flow, must make system of some each roller, and this kind of system is not cheap. To laser system, if the product is round, you may use a X, Y is adjusted. Every send receive unit present price to be 5000 dollars about, and the locomotive cost of indication box is 2500 dollars about. To a process system that does not need to a lot of clamp are adjusted and be safeguarded, you will spend 12500 dollars. " he points out, current, industrial application often uses laser in the industry in distinctive treatment. The product that makes considering these treatment has higher value, so the cost that laser measures a system appears negligible. Say according to Schauer, "In the future, it is especially in high speed treatment, can offer more and more laser products. In receiving the 10 ～ below 20 years, metric industry differs those who become apparent. " low cost laser measures pair of everybody in the industry to remain a target. And Optodyne Inc.

The new MCV that believes it, system of 500 laser calibration is the one condition that to this one party Xiang Mai gives. Its price under 10000 dollars. It can measure guide screw of machine, ball and DRO to undertake in-house linear to CNC machine tool, coordinate corrective. The system includes two component that can aim, stimulate bareheaded namely the component mixes 12.

The viewfinder of 7mm. With Duopule the technology is a foundation, MCV, the 500 laser that contain to be used at the weak opening that blast off and receives first. Laser head and viewfinder all are installed go up in the machine tool, tripod need not be installed in the ground. Offer the traversal speed that gathers 4m/s, the system uses supportive Windows software to undertake counting occupying collect and be analyticed. Dimension is the laser head of 216mm of × of 51mm × 51mm, the characteristic is excel 0.

The stability of 1ppm is checked, precision is 1.

0ppm (1/1000000) , resolution is 0.

03 μ M. In be installed, the technology of laser ball staff that Optodyne company makes, allow an user to fulfil a series of functions: Desired result is linear positional precision; Measure servo to break match; Measure tangent speed; Measure retrorse error; Generate the data that is used at amending a document; Measure tangent speed; Tuning of generation servo controller allows with data from 2.

54mm changes continuously to 76mm radius. The resolution of this system is 0.

0000254mm, can undertake metrical with the speed of 4m/s. Use this laser rod, the X axis coordinate that this main shaft moves is measurable even as general as its big Y to motion, combine X and data of Y axis coordinate, can create the round contrail graph that is measured of main shaft. Besides these equipment, optodyne will be offerred measure 3 axes machine tool to go up all 21 likelihood the system of position error. The president Charles Wang of Optodyne company says, "We call this kind of technology Vector Measue-ment (vector is measured) . Pass installation 4 times, can measure inside the time of 2 ～ 4h give 21 all errors. " he believes, this kind of new system is comprehensive the function of several kinds of instruments. When measuring machine tool error. Wang says, "Groovy method is to use laser interferometer to shoot a machine tool, obtain positional precision. Check dynamic sex next with lever of a ball. What we have now is a laser that can examine all dimension. We can measure all 21 geometry errors. After this, can use same laser undertakes ball lever is measured. An instrument can finish static state and dynamic precision to measure. " by Optical Dimensions Inc.

Manufacturing laser surface surveys a system to detect specially the problem offerred means of settlement of hi-tech, high rate. Name of this kind of system is Lasercheck system, the laser that works with 10Hz undertakes in machining a process automatic surface surface roughness is measured. It explained the limits of shining surface is Ra0 thoroughly.

The president of the company holds general manager J concurrently.

Glenn Valliant says, should measure instrument equipment measurable the specular reflection of a surface and diffuse reflection. "When exterior surface roughness is changed, the distributinging change that comes from the surface is completely OK and affirmatory. Can mix according to specular reflection of diffuse reflection distributing will calculate exterior surface roughness. " the installation price of the Lasercheck system of current independence restrains 25000 dollars, include a laser (the illume angle that adjusts a key) detect with near 40 the specular reflection that comes from the surface and the sensor with smooth diffuse reflection. Valliant says: "Laser puts through time is 30ms about, inside this paragraph of time, instrument record comes from all sorts of bad reflex at its surface. " next special algorithm uses the data that collects for computational surface surface roughness. He explains: "Popularly, appearance scanning length can amount to surface roughness of drawing style surface 4 ～ 5mm, scanning width is decided by the width that measures nib. Contrail of our beam of light grows 6mm of about 5 ～ , wide make an appointment with 1mm. " the surface that Lasercheck measures can be dormant or of motion. He says: "We obtained the process that is close to 607m/min, and this kind of equipment does not need in charge of. " by 3 main softwares setting mode is operated measure an instrument. The spare parts detects fashion states the system is measured by on makings system is ordinal the spare parts of offerred disperse. Roller or conveyer belt detect state a large and successive surface measures an operation. The lab detects use at be being moved by operator hand to go up the spare parts of makings. The user chooses corresponding software mode and the itself that measure an instrument to adjust. Measure the surface with Lasercheck, criterion the surface must clean. Optical Dimensins developed clean method equipment to cooperate to measure the application of the instrument. Valliant says: "We have a lot of craft time to resemble what what do is in on core technology on the spare parts. General we are used compress air and blow custom-builtly except implement fixed. We offer those who be us to measure appropriately the equipment with clean surface indispensible place and accessory. " the change that if resemble the place in grinding working procedure appearing,the data that Lasercheck measuring instrument generates can indicate. This data reflects the change in the emery wheel when emery wheel to load, reflect the effect of nap of the emery wheel in grinding process. But overtime monitoring and the trend in recording a process. Laser triangulation law remains CyberOptics Corp.

The fundamental of production instrument. The Bruce Batten explanation of CyberOptics says: "We go to focusing of laser light beam apparently next reflex of beam of light answers sensor. We collect data on detector. If laser shoots exterior dot to produce change in Z direction, criterion the place that reflex shoots detector also can produce change. Use triangulation law, we can decide two height between the dot are poor accurately. " the contourgraph of Cyberscan Cobra3 dimension of this company can collect the 3 dimension data in height, length, area, bulk, average height and exterior surface roughness. The laser sensor of CyberOptics company is in of 50mm × 50mm is to measure the resolution in the area to come accurately greatly 0.

125 μ M. The sensor of Cobra is secured to be on arm of Y axis shift. Open wide platform to be in Cobra fixed position partly by a 3 dimension target content upper part, and test desk provides X axis campaign. Another product, namely Vantage testing system, can undertake to the area of 152mm × 152mm 3 dimension scan. It can produce picture of height of a landform, resolution comes accurately 0.

125 μ M. Measure limits to be 8000 μ M. Its automatic X, Y workbench, by computer control of the system, to handlers one misses the opportunity of the process designing area of metrical appearance Lv for them. 3 when this company makes or 4 sensor can be united with Vantage or Cobra3 hold together case use. The one big obstacle that laser measures a system to must be overcome is facula dimension. Batten says: "The facula dimension of laser light beam is deciding the size of resolution greatly. We should generate very small imperceptible facula, because can be become,resemble and measure very small feature. If possible sentence, the optics of the good quality that this needs a few lens, but will reduce facula dimension to come the range that exceeds diffractive limit. " he discovers as time elapse, laser system becomes have price competition ability more and more. "The research of laser technology is a popular domain. Like us, people benefits a lot from inside the progress of communication system respect. We use the job now the laser inside limits of 600 ～ 700mm. We like to use range low the laser to 300 ～ 400mm. " Renishaw Inc.

It is the outstanding manufactory that contact surveys a system, its production is used at the hand to move or the coordinate of direct numerical control surveys the laser testing system of machine. By Wolf&The OTP64M optics that Beck makes touchs hairdo to survey head system, allow coordinate to measure the user of machine to be able to add blame contact to detect on its machine tool function. The Denis Zayia of Renishaw says: "We are in Wolf&Beck is measured Renishaw automatic joint was added on the head implement, it still has an OTI6 interface. Accordingly, no matter you are to obtain what kind of contact to measure a head, can mix in PH6M the system on the join on PH10 automatic head. " use coaxial and optical triangulation, this system that measure a head includes laser of a Class2 to arrive in laser facula one arises to spark when focal position in all signal. Because contact of OTP6M imitate standard sparks,measure the output signal of the head, do not need special software to be able to use this laser to measure a head. Zayia explanation says: "Basically need to use contact to spark when some people measure a head to detect major part, but when a pair of spare partses ask to use blame contact to measure, that is a true means. " the value that still still sees laser surveys a system has reduce significantly. "If you notice our Wolf&Beck system, include to measure among them head, interface and all sorts of accessory, its price is 12000 dollars about, should measuring a head is to install the video on machine is measured to measure a head in coordinate. Its price already fell, and still can depreciate further. " in the future, is laser measured can you replace a contact to measure? Zayia notices: "Mechanical is measured will take regnant place, but laser measures equipment to will hold larger share. Cut off measure a head and character, of our majority this kind measures a head to have detached module. Worst circumstance is, you may bend nib. If you make preparation use laser in, and it struck a part in the center, criterion laser can be interrupted. I think of laser fixed costlier. " Erim International Inc.

The perceptive system that special development uses on martial satellite (special integrated alveolus radar) . Their Holo-Vision group developed a kind of laser device that calls Holo Mapper, this device used the knowledge that is a foundation with producing industry to survey a system. The general manager Joseph C of Holo-Vision group.

Marron says, new system can be generated inside a few minutes and record the digital hologram of the spare parts. Holo Mapper job uses laser irradiation at the same time whole spare parts. "We will stimulate beam of light to be divided into beam of light of a target and a referenced beam of light, record next by shoot the hologram that generates to CCD pickup camera. The hologram that uses counting method coding takes the computer that can form picture. Our intelligent characteristic is code or digital signal processing, it allows to we obtain hologram information and be its changeover 3 dimension image. " the pickup camera that Holo-Vision place uses has a 1000 × array of 1000 CCD resembling a department, because this system is likely,1 million 1 data are collected to nod on a spare parts. Use special software, the user can be calculated the 2 dimension of exterior surface roughness, flatness and spare parts are spent. In addition, outside the data that collects on the spare parts can undertake comparative with CAD model, in order to evaluate integrated spare parts precision. The part that measures a model needs 2min about. After measuring, the user can obtain 3 dimension image or outline from inside data instantly almost. Marron explanation says: "To outline, the user presses mouse Zun Jian, hit right key in order to define outline limit. Additional, we also can delimit along circular arc curve, also can undertake digital type plane is changed or record change with digital means to a certain spare parts spare parts. " in Z direction, the system can differentiate piece 0.

5 μ M. Marron says: "We have some of user to want to let us reduce this number, and we also are asking for that direction development. " the spare parts size that current HoloMapper can measure is not more than 178mm of × of 178mm × 178mm. Be in before long in the future, we hope to increase size 305mm of × of 305mm × 305mm. In X and Y direction, when eye shot is 178mm × 178mm, the X of HoloMapper, Y is like element dimension 0.

178mm × 0.

178mm. Marron says: "If someone wants to measure place resembling aperture a kind feature, on CCD array, we get a lot of sample that exceed round diameter. We can undertake child resemble bore diameter in order to decide like element processing a kind feature, precision is good at 0.

178mm. " be worth according to special color scale height, can produce the useful picture that sees with naked eye. Through using 3 dimension glasses, observer can acquire the image since the vertical stroke on screen, can raise visual judgement so. In enter this before new system, the spare parts must be cleaned. The oily film explanation of bequeath of HoloMapper meeting general on the spare parts is high deviation. The spare parts must hold dormant position below systematic laser. Can use insert a spare parts automatically, but Holo-Vision still is operated this kind without the setting. Now, 10 new systems are announced to check in the spot. Morran sees HoloMapper measures engine competition in certain domain and coordinate. "Our user measures the problem that encounters when machine in use coordinate is, accurate part has on larger area when accurate sampling, rate is very slow. And we have however right inside 1 ～ 2min an appearance the capability that gathers 1 million 1 to nod. "Groom the version that uses newest HoloMapper, it is by installation inside crust of a NEMA12, need 4h about " . CNC Milling
