Form Talysurf Series 2 For simultaneous measurement of dimension, form and surface texture

Designed to measure all elements of surface geometry with the greatest possible accuracy inthe shortest possible time.

Curvature, inclination, roughness and waviness all affect the way surfaces interact with othersurfaces. Form Talysurf detects and evaluates all elements with just a single traverse acrossthe component.

Impressive pedigree

The original Form Talysurf wasdeveloped in 1984 specifically forthe precision bearing industry.

As the first instrument ever tomeasure dimension, form andtexture on curved surfaces, itshowcased the unique ability ofTaylor Hobson engineers to leadrather than follow industry trends.

Over the years the basic premisehas been refined, improved andexpanded to suit other industries,but like many truly groundbreakingideas it has never been surpassed.

0.8nm / PGI Plus

Taylor Hobson has shattered the range to resolution barrier with an

unprecedented ratio

12,480,000:1

Designed specifically for the highest level of manufacturing precision, the new PGI Plus

provides 10mm of range with 0.8nm resolution.

What is form?

Form is deviation away fromthe intended nominal shapeof the surface, ignoring variations due to roughnessand waviness.

All objects have measurabledeviations from the intendedshape that can be caused byvarious factors:

• Clamping during machiningthat is too firm or not firm enough

• Inaccuracies of the slides or guide-ways in the machine tool

• Inadequate or improper stress relief of the component

• Sagging of the component under its own weight

• Thermal effects produced during machining

Deviations from intendedshape will affect performanceand useful life of a component.

What is waviness?

Waviness is typically an undesiredmachine tool effect that is almostalways present in manufacturedsurfaces.

Waviness, usually periodic inappearance, is distinguishedfrom roughness by exhibitinglarger horizontal wavelength.

To the extent that waviness is acharacteristic produced by animperfect machine it can beminimized by attention to thefollowing:

• Vibration caused by lack of stiffness or a balance problem

• Deflection of the tool path caused by asymmetric forces

Waviness is especially criticalon surfaces designed to function in contact with othersurfaces.

The measurement of surfacesThe three elements of a surface - dimension, form and texture - are inseparable in the function of a component.Therefore measuring one element without regard to the others can result in misleading or incorrect analysis.

Dimension (nominal shape)Form deviationWavinessRoughness

Measure all three at once

Form Talysurf instrumentsmeasure dimension, form,and texture simultaneously.This ensures that eachelement is evaluated as itshould be - in relation to theother elements and how theyfunction together.

What is dimension?

Dimensions (radius, distanceand angle) are used to definethe functional shape of a surface.

Many objects have obviousshape such as bearing balls orspherical lenses while otherobjects are designed to bewithout shape such as flatsealing surfaces.

The shape of surface featuresand the linear relationshipbetween features can beassessed and compared usingpowerful analysis tools:

• Least squares arc (radius)

• Least squares or minimumzone line (angle)

• True X and Z co-ordinate positions

The elements of a surface are inseparable in the function of a component (not drawn to scale)

Significance of a straight line

Imperative to the measurementof form is the integrity of the reference to which themeasured surface is compared.Form Talysurf traverse unitsare designed and manufacturedto exacting standards.

Either a 50mm (1.97in) or120mm (4.72in) traverselength can be provided.

Both have a precisionstraightness datum and horizontal data logging vialinear scale and reading head.

The datum bar is made of tool steel subjected to a proprietary heat treatment to ensure optimum stability

Datum bar and carriage use lowfriction bearings machined inplace for flatness and squareness

Exceptionally low systemnoise enables maximum useof gauge resolution

A non-influencing belt drive isused to minimize cyclic errors

Data logging to 0.25µm (10µin)assures high resolution andrepeatability

The Form Talysurf traverse unitserves as an absolutely accuratereference for reproduction ofthe measured surface.

component performance will be affected by form, waviness and roughness

deviations in form may cause excessive noiseor premature failure of the component

What is roughness?

Roughness is produced bythe action of the cutting toolor machining process usuallyresulting in process marks.

Function of a component - sliding, sealing, rotating, etc. - dictates what amount ofroughness is necessary forcorrect performance.

Cosmetic appearance or secondary operations such aspainting and plating can alsobe important in choosing aroughness specification.

Cutting tool geometery alongwith machine tool settingssuch as feed rate, depth ofcut and speed influenceroughness as follows:

• Amplitude - vertical distancebetween peaks and valleys

• Spacing - horizontal distance between peaks and valleys

• Slope - sharpness of individual peaks and valleys

Roughness is a deliberate, controllable element of component design and isalways superimposed on thewaviness element.

Calibration of the systemJust as the three elements of a surface function as one, each component of a measuring instrument is designed tocomplement the others. The specification of one component - no matter how outstanding - is meaningless out of contextwith the system. Form Talysurf optimizes system performance by means of calibration over a spherical artifact.

The calibration procedure

Like 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 ofthe polynomial are determinedby means of calibration.

The accuracy of this calibrationdirectly affects the accuracyof radius, form and surfacetexture measurement.

To obtain these coefficients,Form Talysurf instrumentsare typically calibratedthrough the measurementof a high precision sphericalartifact - a method of calibrationpatented by Taylor Hobson.

Checking the stylus tip

With many surface measuringsystems, the size, shape andcondition of the stylus tip areassumed to be constant interms of data processing.

In practice the stylus tip mayvary due to manufacturingtolerance, routine wear orphysical damage.

With Form Talysurf the stylus istraversed over the sphericalartifact making contact at allpoints along the radius ofthe tip in the measurementdirection.

By measuring over a sphericalcalibration artifact, the usercan detect effects due to stylusdamage and deviations of sizeand shape.

Checking the gauge range

All Taylor Hobson gauges havean exceptional ratio between themaximum vertical displacement(range) and the minimum verticalstep (resolution).

65,536:1 is the range to resolutionratio for the Inductive gaugewhich has 1mm (0.04in) rangeand is calibrated over a 12.5mm(0.49in) radius.

780,000:1 is the ratio for thePhase Grating Interferometer(PGI) gauge which has 10mm(0.4in) range and is calibratedover an 80mm (3.15in) radius.

12,480,000:1 is the ratio for thePGI Plus gauge which has 10mm(0.4in) range with 0.8nm (0.03µin)resolution and is calibrated overan 80mm (3.15in) radius.

The combination of range, highresolution and calibration over a spherical artifact assures flexibility and accuracy for manycommon as well as special measuring situations:

Inclination and straightness canbe evaluated over longer distances

Multiple steps on a componentcan be measured at once

Leveling of components prior tomeasurement is often unnecessary

Curved or contoured surfaces can be easily measured

Checking the gauge linearity

The more linear a system is the more likely that stylusmovement at the bottom of the range is reproduced exactlythe same as movement at thetop of the range and anywherein between.

Step height artifacts are widelyused for calibration of systemsnot intended for form analysis.In this simple process a narrowband in the middle of the gaugerange is checked and calibrated.

With Form Talysurf the entiregauge range is tested as thestylus is traversed over thespherical artifact. This assureslinearity of the entire measuringrange regardless of the tiltingdirection of the componentbeing measured.

Processor functions

Form Talysurf uses powerfulsoftware to combine data generated by vertical movementof the stylus with data collectedfrom the linear scale andreading head in the horizontaltraverse unit. The result is a grid array of as many as120,000 data points, each withunique spatial characteristics.

Arcuate stylus motion error

Patented 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.

Automatic and powerful

Calibration is programmableand essentially automatic.A positioning stage is used tomanually locate the crest of the ball in the 'Y' axis. Crestingin the 'X' axis, movement of thetraverse to its start position andthe actual measurement are all automatic.

The result is a true systemcalibration - all elements havebeen checked:

• Arcuate stylus motion error

• Gauge non-linearity

• Stylus tip geometry

• Instrument stability

• Traverse datum and data logging

• Gauge / stylus mechanical stiffness

• Processor functions

measure dimension, form and texture at once witha single traverse over curved surfaces

calibration over a ball checks gauge range, linearity,stylus condition and processor functions

measureable form features may be spherical,aspherical, concave, convex, internal or external

µltra Softwareµltra was developed first of all to function in accordance with the highest standards of metrology. That it turned out also to be clever, comprehensive and easy-to-use reflects the Taylor Hobson expertise at putting metrology to work in support of manufacturing.

Total system control

µltra takes charge of all functions to eliminate hardware / software conflictstypically created by third partyor after market softwarepackages. Mechanical performance is optimizedby use of patented software routines and proprietarycalibration techniques.

• Mechanical functions -positioning and speed of all axis movements

• Administrative functions -user preferences, data storage and retrieval

• Analysis functions -application of filters and constants, calculation of results

• Display functions - screen graphics, customized templates, print commands

Compatibility

µltra was designed to be fullycompatible with older TaylorHobson data file formats,thus enabling re-analysisand comparison of old data. It also has a programmablefacility for the simple export ofresults to standard packagessuch as SPC and ExcelTM.

Compliance with international standards

Whatever the parameter andwherever in the world it happensto be measured it is guaranteedto be correct. µltra alsoadheres to industrial metrologydisciplines as practiced byleading manufacturers aroundthe globe.

• Calibration routines areeasily integrated intocorporate ISO 9001procedures

• Artifacts used for calibrationcan be identified andreferenced to certification date

• Calibration history regarding operator, artifact and dateis automatically stored

• Calibration is recommendedwhenever the stylus arm is changed. To simplify this process all stylus armconfiguration dimensions are stored for easy recall

Industrial strength interface

Although written withfamiliar Windows conventions,µltra has the look and feel of a machine tool interface.Commands are direct, purposeful and driven byintuitive logic. Perhaps forthe first time in metrology the computer is a bridgeinstead of a barrier betweenoperator and instrument.

µltra powers Talycontour dimensional contour measuring systems

µltra powers Talyrond roundness and cylindricity measuring systems

µltra simplifies training and eliminates the need for dedicated, single system operators


13

Multi-instrument architecture

µltra takes full advantage ofclient/server technology andis designed to drive all TaylorHobson hardware devicesincluding Form TalysurfSeries instruments andTalyrond roundness systems.

• Operators familiar with µltra can easily operate multiple instruments

• No need for dedicated, single instrument operators

• Transfer of knowledge is simplified when operatorsare promoted or transferred

• Network ready for central data storage and output to network printers

Comprehensive analysis

µltra includes as standardeverything important to themeasurement of surface finish. All the basic roughnessand waviness parametersare here along with advancedanalysis tools that are eitherstandard or optional dependingon system configuration.

• Contour analysis

• Dual profile

• Aspheric form

• Feature exclusion tool

• Feature zoom tool

• Form analysis

• Point to point distance

• Radius measurement

• Angle measurement

Automation for consistencyand safety

Saving time is just one benefitof automation. Horizontal,vertical and tilting movementsare programmable to provideconsistent start positioning.Minimizing operator interventionalso minimizes damagecaused by mishandling.

• Automatic start positioning -location of the stylus on thecomponent is repeatable and correct

• Automatic measuring runs -every step is performed in the right sequence inthe right location

• Automatic analysis routines -filters, evaluation methodsand parameters arealways identical

automation safely positions the stylus withhorizontal, vertical and tilting movements

start and stop positions are programmable toprevent damage to the stylus

multiple locations on a component can bemeasured within an automatic routine

µltra Surface Finish software - at work on a typical componentTo illustrate the effectiveness with which µltra can analyze all elements ofsurface texture simultaneously, a manufactured component with curved,straight and inclined features will be measured with a single traverse.

In figure 1. the elements markedin pink have been excluded. An LSLine form fit analysis is applied tothe remaining sections to determinetotal profile deviation (Pt).

In figure 2. the "curtains" areclosed on all but one arcuatesection of the profile which consists of approximately 15,000horizontal data points.

The result is initially displayed as a raw profile consisting of approximately 100,000 horizontal data points. µltra provides two tools for isolating features of the component for detailed analysis. The exclusion method is used when multiple sections are considered and the zoom method is used for individual profile elements.

Dimension, Form, Roughness and Waviness AnalysisAlthough µltra can be provided without Form Analysis this powerful featureis recommended whenever a component has curved or inclined features orotherwise deviates from a straight line. The true functional shape of elements can be examined by means of geometric references such as:

• Least Squares Arc • Least Squares Line • Minimum Zone Line

In figure 3. errors of form along the radius are shown clearly. A perfect sphere would appear as a straight line and the Pt valuewould approach zero.

In figure 4. the roughness alongthe radius is displayed at highmagnification. Typical roughness parameters have been calculatedusing conventional filters.

Figure 3.

Figure 4.

zoom section of radius

detail of radius shown in zoom section

Both radius and, significantly, deviation from true radius can be analyzed at once via removal of the LS Arc.After removal of the LS Arc, conventional filters can be applied to determine roughness, waviness, material ratio and other surface finish parameters. µltra provides more than 95 different parameters.

16

Inclination and alignmentA significant advantage of wide gauge range is in staging of the component to be measured. With either the inductive gauge (1mm range) or the PGI gauge (10mm range), simply position the component so that all features to be measured are within the gauging range.

As the stylus moves up and down, the integrity of the data is assured because linearity overthe entire range has been considered in the calibration process. µltra software handles themanipulation and analysis of the data quickly and easily.

In figure 5. waviness parameterson the horizontal surface have beencalculated using conventional filters.The inclined surface may also beassessed independently.

In figure 6. roughness parameterson the inclined surface have beencalculated using conventional filters.The horizontal surface may also beassessed independently.

Figure 5.

Figure 6.

zoom section of inclined surface

detail of inclined surface shown in zoom section

In this example the zoom method has been used to isolate the inclined feature of the component. In addition, thefeature has been aligned to horizontal and can now be used as a reference datum for point-to-point distancemeasurements and determination of surface tilt, intercept and pitch.

Form AnalysisSoftware(standard with PGI systemsoptional with inductive)

Form Analysis Software Code 112/2845-01

Form error: calculated with reference to a best fit concaveor convex circular arc orstraight line, including allsurface roughness detail.Alternatively with reference to a minimum zone (which isthe minimum separationbetween two parallel linescontaining the data set).

Radius: using a least squaresbest fit, the radius of concaveor convex circular arcs can be automatically calculatedfrom selected data. The optionto exclude unwanted surfacefeatures such as edges isalso available. Alternatively,the absolute radius can beset to analyse the actualdeviation from a design master.Other calculated parametersinclude the center co-ordinateand pitch.

Angle (slope): using a straightline or minimum zone algorithm,surface tilt can be determinedand removed prior to parameteranalysis. Other calculated valuesinclude intercept and pitch.

Dimension: the linear relationshipof surface features can beassessed and compared, due to the ability to calculate trueX and Z co-ordinate positions.

The above quoted technical data is for measurementstaken in a metrology laboratory controlled environment:20ºC ± 1ºC (68ºF ± 1.8ºF), draft free, and isolatedfrom low frequency floor borne vibration.

Quoted uncertainties are at 95% confidence inaccordance with recommendations in the ISO Guide to the expression of uncertainty inmeasurement (GUM: 1993)

NOTE:Taylor Hobson pursues a policy of continualimprovement due to technical developments. We therefore reserve the right to deviate from catalog specifications.
