Form TalysurfIntra


Form Talysurf IntraFor simultaneous measurement of dimension, form and surface roughness. Curvature, inclination,roughness and waviness all affect the way surfaces interact with other surfaces. Form Talysurf Intradetects and evaluates all elements with just a single traverse across the component.Impressive pedigreeThe original Form Talysurfwas developed in 1984 for theprecision bearing industry.As the first instrument ever tomeasure dimension, form andtexture on curved surfaces, itdemonstrated the ability ofTaylor Hobson engineers tolead instead of follow surfacemeasurment industry trends.Since then the basic premisehas been refined, improvedand expanded to suit otherindustries but like many trulygroundbreaking ideas it hasnever been surpassed.Form Talysurf Intra is surface finishmetrology engineered for the wayyou work...wherever you work.It can be used with the Processor Control Module for completelyportable operation or with a PC to function as a dedicated inspectionstation...or both.Best of all, Intra moves easily from clean room to shop floor and backagain. Even casual operators will be able to maintain high throughputwith reliable results.Now, for the first time, you can have surface finish inspection thatcontrols your manufacturing process without disrupting yourmanufacturing schedule.2


Choosing the right productForm TalysurfIntraSimple roughness parameters like Ra can be checked with our Surtronic series instruments. If you needadvanced analysis, higher levels of accuracy or greater flexibility, Form Talysurf Intra is the perfect choice.It combines industry leading specifications with simplicity of operation for unbeatable practicality and value.Analysis fundamentalsThe measurable elements ofa surface are dimension, form,roughness and waviness. Manyhigh specification componentsrequire analysis of all four.Dimension - the functionalshape of a surface as definedby radius, angle, distance, andthe linear relationship betweenfeatures.Form - deviations from theintended shape of a surface(flat, spherical, tapered, etc.);often caused by machine toolinaccuracies.Roughness - a deliberate,controllable element of thecomponent design producedby the action of the cutting toolor machining process.Waviness - an undesireablemachine tool effect resultingfrom vibration, lack of stiffnessor other instabilities in themachining process.Skidless measuring systemMany roughness checkers useskidded pick-ups to guide thestylus over the workpiece, withthe workpiece itself forming thedatum for measurement.Because the skid also acts asa mechanical filter, removingor altering general form andwaviness characteristics, thecollected data is not suitablefor advanced analysis.Intra is the right choiceFor correct data collection thegauge must pass over thecomponent in a straight linesuch that only the stylus tipcomes in contact with thesurface under test.Vertical stylus movement isrelative to the traverse datum,a reference bar that has beenlapped or precision groundto an extremely high flatnessand straightness tolerance.Form Talysurf Intra is skidlessand can be used for waviness,profile and other parameterssuch as Material Ratio withabsolute confidence in themeasurement results.For your industryForm Talysurf Intra offersexceptional productivity fora wide range of industriesand applications.For your budgetFor general purpose or forsolving a specific applicationproblem, Form Talysurf Intracan be configured to performwithin your budget.For your futureUnlike closed end systemsthat will be obsolete whenyour requirements change,Form Talysurf Intra can beexpanded to meet whateverthe future brings.skidless tracing arms provide access to internalfeatures such as ball tracks and ring grooveshigh resolution skidless pick-up is necessaryfor straightness and waviness measurementsmeasureable form features may be spherical,aspherical, concave, convex, internal or external3


Calibration of the systemJust as the three elements of surface texture function as one, each element of a measuring system is designed tocomplement the others. The specification of one component - no matter how outstanding - is meaningless out ofcontext with the system. Form Talysurf Intra optimizes system performance by means of calibration over a ball.The calibration procedureLike most instruments of thistype, the Form Talysurf stylusmoves in an arcuate manner.A method to linearize datameasured in this way waspioneered by Taylor Hobson.With this method a polynomialis applied to the readings fromthe gauge. The coefficients of thepolynomial are determined bymeans of calibration.The accuracy of this calibrationdirectly affects the accuracy ofradius, form and surface texturemeasurement.To obtain these coefficients,Form Talysurf instruments aretypically calibrated throughthe measurement of a highprecision spherical artifact - amethod of calibration patentedby Taylor Hobson.Verify processor functionsForm Talysurf uses powerfulsoftware to combine the datagenerated by vertical movementof the stylus with data collectedfrom the linear scale and readinghead in the horizontal traverseunit. The result is a grid arrayof as many as 120,000 datapoints, each with unique spatialcharacteristics.Compensate correctly forarcuate stylus motion errorPatented algorithms are appliedthat compensate for arcuatestylus motion error. This erroroccurs because data is collectedin X-Z coordinates even thoughthe stylus arm is moving in an arc.DistanceRadiusAngleAutomatic and powerfulCalibration is programmable andessentially automatic. A positioningstage is used to manually locate thecrest of the ball in the 'Y' axis. Crestingin the 'X' axis, positioning of thetraverse to its start location and theactual measurement are all automatic.The result is a true system calibration;all elements that may influence themeasurement have been checked:• Arcuate stylus motion error• Gauge non-linearity• Stylus tip geometry• Instrument stability• Traverse datum and datalogging• Gauge / stylus mechanicalstiffness• Processor functionsCalibration frequencyCalibration is recommended wheneverthe stylus arm is changed. To simplifythis process all stylus arm configurationdimensions are stored for easy recall.Calibration history regarding operator,artifact and date is automaticallystored and artifacts used for calibrationcan be identified and referenced tocertification date.Linearity and wide range assure accurate measurement of dimension, form and texture4


Correlation of resultsForm TalysurfIntraManufacturers who outsource expect their suppliers to deliver parts that meet specification. You know the partsare good but the instrument your customer uses to inspect them says they are bad. Lack of correlation can occureven when the instruments are configured the same way as to filter, cut-off and length of trace.Different suppliers,different resultsIn the case of mating pieces,one supplier makes part A,another makes B. Both saythe roughness is acceptablebut the end user may find thatneither part meets the spec.Some of the lack of correlationbetween different brands ofinstruments or even betweeninstruments of the same brandcan be partially attributed tothree factors:• speed of traverse• condition of the stylus• gauge linearitySpeed of traverseMost roughness checkers aretime based, collecting data fora fixed period of time instead ofa precise, constant distance.Anything that affects speed oftraverse - wear, dirt, slippage,etc. - affects the quantity andspacing of the collected datapoints which in turn affect themeasurement results.Form Talysurf Intra utilizes aglass scale and reading headto assure that data collectionis accurate and consistent.Every measurement on everyinstrument is calculated fromthe exact same quantity ofidentically spaced data points.Stylus conditionWith many surface measuringsystems, the size, shape andcondition of the stylus tip areassumed to be constant in termsof data processing. In practicethe stylus tip may vary due tomanufacturing tolerance, routinewear or physical damage.During calibration with a FormTalysurf, the stylus is traversedover the spherical artifact tomake contact at all points alongthe radius of the conisphere tipin the measurement direction. Bythis method, the user can detecteffects due to stylus damage ordeviations of size and shape.Gauge linearityIntra is calibrated over a ballto check linearity of the entire1mm gauge range. Most othersystems use a step master oran Ra patch that calibratesonly over a very narrow band.The assumption is that if thegauge is linear over that bandit is linear over the full range.Unless your measurements areall taken within the same verticalposition of the gauge range andnever exceed the amplitude ofthe step height master, the datayou collect may be non-linearwhich will cause incorrect results.calibration over a ball checks stylus condition,gauge range, linearity and processor functionsform errors cause assembly problems, inefficientoperation and premature failure of the componentmeasure dimension, form and texture at once witha single traverse over curved or straight surfaces5


µltra softwareWhen Form Talysurf Intra is used with a PC, our industry leading software takescontrol of all mechanical, administrative, analysis and display functions. µltra isnetwork ready for central data storage and output to network printers. Users willbenefit from ease of use as well as advanced analysis techniques.µltra takes full advantage of Intra’s wide gauge range and its ability to measure curved straight and inclined featureswith a single traverse. This powerful software uses exclusion, removal and zoom tools to let you identify and isolatecomponent features for detailed analysis of dimension, form and texture without re-measuring the part.In this example, the zoom tool is used to isolate an arcuate feature. Next, the radius and, significantly, deviation fromtrue radius will be analyzed via removal of the LS Arc. After removal of the LS Arc, conventional filters can be appliedto determine roughness, waviness, material ratio and more than 95 different surface finish parameters.measuring path for raw profiledetail of radius shown in zoom section6
