XL系統(tǒng)組件

XL-80 system diagramThe basis of the new system is a compact laser head (XL-80) and an independent environmental compensator system (XC-80). A tripod and stage may also be required depending upon the application.  

Together with measurement optics and software they form a highly accurate measurement and analysis system that can be stored and transported in one of the optional custom designed storage/transport cases.

 

XL-80 laser unit

XL-80 Laser unitThe XL-80 laser produces an extremely stable laser beam, with a wavelength that is traceable back to national and international standards.

  • Laser frequency stability  ±0.05 ppm over 1 year and ±0.02 ppm over 1 hour is achieved by dynamic thermal control of the laser tube length to within a few nanometres.
  • Linear measurement accuracy  ±0.5 ppm over the whole environmental range ie, from 0 ºC - 40 ºC (32 ºF - 104 ºF) and 650 mbar - 1150 mbar. Readings can be taken at up to 50 kHz, with a maximum linear measurement speed of 4 m/s and a linear resolution of 1 nm; even at maximum speed.
  • Integrated USB means there is no requirement for a separate laser-to-PC interface.
  • LED status lights indicate the laser status and signal strength, providing a convenient alternative to the software’s “on-screen" indicators.
  • Switchable between standard (40 m) and long (80 m) range modes.
  • Analogue I/O port allows for analogue signal output and a trigger signal input.
  • Warm-up time is less than 6 minutes.
  • External, switch mode power supply ensures 90 V - 264 V flexibility in input voltage.

All of the above features make the XL-80 quick and easy to use.

Class II laser safety labelIn accordance with (IEC) EN60825-1, Renishaw XL-80 lasers are Class 2 lasers and safety goggles are not required. Always refer to the system manual for safety details before operating the system for the first time.

 

XC-80 compensator and sensors

XC-80 CompensatorThe XC-80 compensator is a crucial factor in your XL system’s linear measurement accuracy. Featuring “intelligent sensors" that process the readings at source, the compensator very accurately measures air temperature, air pressure and relative humidity. Changes in these conditions can effect the wavelength of the laser light and the measurement readings taken.

The XC-80 uses the sensor readings to modify the nominal value of the laser wavelength to give a true value, which is then used in calculations to virtually eliminate any measurement errors resulting from these variations.

If you are interested in accuracy you NEED effective wavelength compensation.

Key features of XC-80 include:

  • Uniform compensation - The design of the XC-80 and sensors ensures uniform and extremely accurate readings over the full range of environmental operating conditions.
  • Frequent sensor updates - This can be done automatically every seven seconds, as indicated by LED status lights on the XC-80 unit.
  • Integrated USB - The inetgral USB connection means there is no separate PC interface and no separate power supply (the USB supplies the XC-80 and sensors' power).
  • Lightweight -  The XC-80 weighs 550 g, and together with the XL-80, weighs just over 3 kg (including connecting cables, XL power supply and sensors).
  • Intelligent air and material temperature sensors - The integral microprocessors analyse and process the sensor's output before sending digital temperature values to the XC-80 compensator. This offers more secure measurements and is a key reason why the XC-80 is so compact and also ensures sensors are fully interchangeable without comprimising accuracy.
  • Up to three material temperature sensors can also be attached to the XC-80 compensator to allow linear measurements to be normalised to a standard material temperature of 20 °C.
  • Versatile sensor cables - The standard 5 m long sensor cables are detachable for easy replacement and can be screwed together for extended lengths on longer machines.

Note: Environmental compensation is NOT required for angular or straightness measurements when using a Renishaw system as these are calculated from differences in two beam paths close together, where the environmental factors self cancel. As rotary axis, flatness and squareness measurements are also based on these measurements they also do not require environmental compensation.

 

Tripod and stage

Unless you are using a dedicated measurement rig, then you are likely to need a mounting stage (and in most cases a tripod) to adjust the laser’s position relative to the desired measurement axis.

  • XL-80 on stageThe XL mounting stage allows for precise angular rotation and translation of the XL-80.  It is designed to be left attached to the laser unit for easy storage and quick set-up.
  • A "quick fit/release" mechanism enables rapid and secure fixing to a tripod.  For those applications where tripod mounting is not convenient, e.g. for mounting directly on a machine tool table, the stage and laser can also be mounted on to most standard magnetic bases, using an optional adapter with M8 thread.
  • The new Universal tripod has been extensively tested to provide a stable, adjustable base in a compact, lightweight unit.

性能和測(cè)試

Laser calibration benchAll of Renishaw's experience in metrology and laser interferometry is to be found in each and every measurement system that it produces. Our aim is to deliver the specified accuracy, with full traceability and confidence that the laser system will continuously deliver that accuracy day-after-day where it counts, in the workplace.

All lasers and ballbars are calibrated at the Renishaw factory against reference systems with traceability to national standards.

 

System performance

XL-80, XC-80 and sensors

Performance specifications are verified to international procedures against a documented system error budget, with system accuracy quoted to 95% confidence level (k = 2), which is valid across the full environmental operating range.

Without reliable and accurate wavelength compensation, errors of 20 ppm - 30 ppm would be common. Great effort has been taken to ensure Renishaw’s XC-80 compensation system and sensors are accurate across the entire operating range of the system. It is this that maintains ±0.5 ppm linear measurement accuracy from 0 ºC - 40 ºC (32 ºF - 104 ºF) and over the full air pressure range.

XL-80所用的測(cè)量光學(xué)鏡組

Optic familyRenishaw measurement optics enable you to measure linear, pitch, yaw, horizontal and vertical straightness along any axis. Additional optic kits are available to enable measurement of surface flatness and squareness of axis.

The same optics can be used with XL-80 or ML10 systems, ensuring consistency of measurement set-ups and procedures. All measurements are interferometric and therefore use the traceable international standard wavelength of laser light, allowing you to have total confidence in the results.

For rotary axis calibration, please see RX10 rotary axis calibration section and for other optical accessories to assist in set-up and measurement, please see the optics accessories section.

 

Features and benefits

Linear optics kitInterchangeable - The unique design of linear, angular and straightness optics enables easy interchange for different measurements, without having to re-align the laser.

Convenient - Moving optics have no cables to drag or snag, for best accuracy and convenience.

Low mass aluminium optics - The optics are manufactured in aluminium, therefore the optics' low mass is especially relevant if measuring pitch errors on horizontal arm CMMs and for dynamic measurements.

Quick acclimatisation - Some competitor systems use stainless steel optic housings. These are much heavier than Renishaw's aluminium optics and have a lower thermal conductivity, therefore taking longer to acclimatise to the shop environment.

英國(guó)雷尼紹新型XL-80激光干涉儀


英國(guó)雷尼紹新型XL-80激光干涉儀詳細(xì)介紹:

    在超精密的測(cè)量和校準(zhǔn)方面,激光干涉儀已經(jīng)扮演多年極重要的角色。但是近年來隨著自動(dòng)化運(yùn)動(dòng)系統(tǒng)性能大幅提高,面對(duì)半導(dǎo)體和傳統(tǒng)金屬加工業(yè)的需求,現(xiàn)有激光系統(tǒng)的性能已無法滿足一些客戶的要求。
     Renishaw的新型XL-80激光干涉儀能夠滿足和超越實(shí)際工業(yè)規(guī)范水平,提供4m/s的測(cè)量速度和50kHz記錄速率。即使在的數(shù)據(jù)記錄速率下,系統(tǒng)準(zhǔn)確性可達(dá)到±0.5ppm(線性模式)和1納米的分辨率,這些改進(jìn)意味著工程師仍能使用可溯源性激光干涉的優(yōu)勢(shì),幫助解決現(xiàn)代化機(jī)器設(shè)計(jì)問題。
     系統(tǒng)精度比原有的對(duì)應(yīng)產(chǎn)品ML10激光系統(tǒng)有所提升,在整個(gè)日常溫度、氣壓和濕度不同工作環(huán)境下,均可達(dá)到±0.5ppm的精度。環(huán)境讀數(shù)使用XC-80智能傳感系統(tǒng)進(jìn)行讀取,每7秒更新一次激光讀數(shù)補(bǔ)償值。還有一點(diǎn)很重要,與Renishaw的ML10系統(tǒng)一樣,所有測(cè)量值均采用穩(wěn)定的氦氖激光源的波長(zhǎng)為基準(zhǔn),保證能夠溯源至的長(zhǎng)度標(biāo)準(zhǔn)。
     此新系統(tǒng)可以與現(xiàn)有的ML10系統(tǒng)光學(xué)鏡組*兼容,使目前數(shù)千ML10用戶能夠升級(jí)到新系統(tǒng),并同時(shí)保留其在光學(xué)鏡組、程序和人員培訓(xùn)上的原有投資。
     我們還提供已更新的Renishaw軟件版本(LaserXL?及QuickViewXL?),能夠以用戶熟悉的、易于使用的格式提供數(shù)據(jù)。LaserXL?能夠執(zhí)行循序漸進(jìn)式的測(cè)量,以方便對(duì)大多數(shù)機(jī)床按標(biāo)準(zhǔn)進(jìn)行檢驗(yàn),QuickViewXL?軟件能夠在屏幕上實(shí)時(shí)地顯示激光讀數(shù)。
     您只要看一眼Renishaw的新型XL-80激光裝置和XC-80補(bǔ)償器,就會(huì)注意到它們比原有的ML10和EC10小了許多?,F(xiàn)在,二者總重僅3公斤多一點(diǎn)(包括連接電纜、電源和傳感器),比原來減輕了70%。當(dāng)然,隨著激光頭和補(bǔ)償器尺寸減小,其他系統(tǒng)組件,例如三腳架和云臺(tái)也相應(yīng)地減小以便相配,因此整個(gè)系統(tǒng)(除了三腳架)的裝運(yùn)箱減小了許多?,F(xiàn)在,最小的“腳輪箱"只有原來箱子的一半大一點(diǎn)點(diǎn),卻可以攜帶整個(gè)線性和角度測(cè)量系統(tǒng),并有放置RenishawQC10球桿儀組件的位置。這個(gè)高度便攜的“檢查和修正"系統(tǒng)總重不到15公斤,同類產(chǎn)品無以匹敵。
     為了與系統(tǒng)的其他組件的便攜性相匹配,我們?cè)O(shè)計(jì)了新型三腳架和裝運(yùn)箱,僅重6.2公斤。
     激光頭和云臺(tái)體積很小,能夠方便地固定在標(biāo)準(zhǔn)磁性座上,可以在不方便使用三腳架固定的應(yīng)用條件下使用。XL-80激光測(cè)量系統(tǒng)的光束高度和光學(xué)鏡組尺寸與ML10系統(tǒng)一樣,因此也可以直接放在花崗巖工作臺(tái)(不使用三腳架云臺(tái))上,進(jìn)行坐標(biāo)測(cè)量機(jī)的校準(zhǔn)。
    Renishaw已將激光的預(yù)熱時(shí)間縮短至大約僅6分鐘。預(yù)熱速度較同類系統(tǒng)快,因此用戶等待時(shí)間減少了,用于測(cè)量工作的幾率增加了,這對(duì)于機(jī)器校準(zhǔn)服務(wù)商和那些需要在一個(gè)地點(diǎn)執(zhí)行多項(xiàng)測(cè)量的用戶而言非常重要。
     現(xiàn)在,信號(hào)增益的開啟和關(guān)閉是一項(xiàng)標(biāo)準(zhǔn)功能,使其具有80米線性測(cè)量距離的能力。若短距離應(yīng)用時(shí),則可以提高信號(hào)強(qiáng)度。激光信號(hào)通過USB連線直接輸出到電腦上(無需單獨(dú)的接口),輔助功能端口可提供模擬信號(hào)及工廠按需設(shè)定的數(shù)字信號(hào)輸出。
      XL-80激光頭的配置集原ML10G/Q/X多種任選功能于一體,功能更完善。
     XL-80系統(tǒng)具有長(zhǎng)達(dá)3年標(biāo)準(zhǔn)的全面保修,并可以以優(yōu)惠的價(jià)格選購(gòu)延長(zhǎng)保修時(shí)間為5年。對(duì)于使用ML10的老用戶和使用其他廠商制造的同類系統(tǒng)的新客戶,我們均提供一些特別優(yōu)惠政策。
