Form Talysurf Series 2 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 in the shortest possible time. Curvature, inclination, roughness and waviness all affect the way surfaces interact with other surfaces. Form Talysurf detects and evaluates all elements with just a single traverse across the component.
Impressive pedigree The original Form Talysurf was developed in 1984 specifically for the precision bearing industry. As the first instrument ever to measure dimension, form and texture on curved surfaces, it showcased the unique ability of Taylor Hobson engineers to lead rather than follow industry trends. Over the years the basic premise has been refined, improved and expanded to suit other industries, but like many truly groundbreaking ideas 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. 3
The measurement of surfaces The 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. Measure all three at once
What is form?
What is waviness?
Form Talysurf instruments measure dimension, form, and texture simultaneously. This ensures that each element is evaluated as it should be - in relation to the other elements and how they function together.
Form is deviation away from the intended nominal shape of the surface, ignoring variations due to roughness and waviness.
Waviness is typically an undesired machine tool effect that is almost always present in manufactured surfaces.
What is dimension?
All objects have measurable deviations from the intended shape that can be caused by various factors:
Dimensions (radius, distance and angle) are used to define the functional shape of a surface.
• Clamping during machining that is too firm or not firm enough
Many objects have obvious shape such as bearing balls or spherical lenses while other objects are designed to be without shape such as flat sealing surfaces.
• Inaccuracies of the slides or guide-ways in the machine tool
The shape of surface features and the linear relationship between features can be assessed and compared using powerful analysis tools: • Least squares arc (radius) • Least squares or minimum zone line (angle)
• Inadequate or improper stress relief of the component • Sagging of the component under its own weight • Thermal effects produced during machining Deviations from intended shape will affect performance and useful life of a component.
Waviness, usually periodic in appearance, is distinguished from roughness by exhibiting larger horizontal wavelength. To the extent that waviness is a characteristic produced by an imperfect machine it can be minimized by attention to the following: • Vibration caused by lack of stiffness or a balance problem • Deflection of the tool path caused by asymmetric forces Waviness is especially critical on surfaces designed to function in contact with other surfaces.
• True X and Z co-ordinate positions

What is roughness?
Significance of a straight line
Roughness is produced by the action of the cutting tool or machining process usually resulting in process marks.
Imperative to the measurement of form is the integrity of the reference to which the measured surface is compared. Form Talysurf traverse units are designed and manufactured to exacting standards.
Function of a component sliding, sealing, rotating, etc. - dictates what amount of roughness is necessary for correct performance. Cosmetic appearance or secondary operations such as painting and plating can also be important in choosing a roughness specification. Cutting tool geometery along with machine tool settings such as feed rate, depth of cut and speed influence roughness as follows:
Either a 50mm (1.97in) or 120mm (4.72in) traverse length can be provided. Both have a precision straightness datum and horizontal data logging via linear scale and reading head. ◗ The datum bar is made of tool steel subjected to a proprietary heat treatment to ensure optimum stability
• Amplitude - vertical distance between peaks and valleys
◗ Datum bar and carriage use low friction bearings machined in place for flatness and squareness
• Spacing - horizontal distance between peaks and valleys
◗ Exceptionally low system noise enables maximum use of gauge resolution
• Slope - sharpness of individual peaks and valleys
◗ A non-influencing belt drive is used to minimize cyclic errors
Roughness is a deliberate, controllable element of component design and is always superimposed on the waviness element.
component performance will be affected by form, waviness and roughness
◗ Data logging to 0.25µm (10µin) assures high resolution and repeatability The Form Talysurf traverse unit serves as an absolutely accurate reference for reproduction of the measured surface. deviations in form may cause excessive noise or premature failure of the component

Calibration of the system Just as the three elements of a surface function as one, each component of a measuring instrument is designed to complement the others. The specification of one component - no matter how outstanding - is meaningless out of context with the system. Form Talysurf optimizes system performance by means of calibration over a spherical artifact. The calibration procedure
Checking the stylus tip
Checking the gauge range
Like most instruments of this type, the Form Talysurf stylus moves in an arcuate manner. A method to linearize data measured in this way was pioneered by Taylor Hobson.
With many surface measuring systems, the size, shape and condition of the stylus tip are assumed to be constant in terms of data processing.
All Taylor Hobson gauges have an exceptional ratio between the maximum vertical displacement (range) and the minimum vertical step (resolution).
In practice the stylus tip may vary due to manufacturing tolerance, routine wear or physical damage.
65,536:1 is the range to resolution ratio for the Inductive gauge which has 1mm (0.04in) range and is calibrated over a 12.5mm (0.49in) radius.
With this method a polynomial is applied to the readings from the gauge. The coefficients of the polynomial are determined by means of calibration. The accuracy of this calibration directly affects the accuracy of radius, form and surface texture measurement. To obtain these coefficients, Form Talysurf instruments are typically calibrated through the measurement of a high precision spherical artifact - a method of calibration patented by Taylor Hobson.
With Form Talysurf the stylus is traversed over the spherical artifact making contact at all points along the radius of the tip in the measurement direction.
780,000:1 is the ratio for the Phase Grating Interferometer (PGI) gauge which has 10mm (0.4in) range and is calibrated over an 80mm (3.15in) radius.
By measuring over a spherical calibration artifact, the user can detect effects due to stylus damage and deviations of size and shape.
12,480,000:1 is the ratio for the PGI Plus gauge which has 10mm (0.4in) range with 0.8nm (0.03µin) resolution and is calibrated over an 80mm (3.15in) radius.
Distance
The combination of range, high resolution and calibration over a spherical artifact assures flexibility and accuracy for many common as well as special measuring situations: ◗ Inclination and straightness can be evaluated over longer distances
Radius
Angle
◗ Multiple steps on a component can be measured at once ◗ Leveling of components prior to measurement is often unnecessary ◗ Curved or contoured surfaces can be easily measured
Linearity and wide range assure accurate measurement of dimension, form and texture

Form Talysurf Series 2
Checking the gauge linearity
Arcuate stylus motion error
The more linear a system is the more likely that stylus movement at the bottom of the range is reproduced exactly the same as movement at the top of the range and anywhere in between.
Patented algorithms are applied that compensate for arcuate stylus motion error. This error occurs because data is collected in X-Z coordinates even though the stylus arm is moving in an arc.
Step height artifacts are widely used for calibration of systems not intended for form analysis. In this simple process a narrow band in the middle of the gauge range is checked and calibrated.
Automatic and powerful
With Form Talysurf the entire gauge range is tested as the stylus is traversed over the spherical artifact. This assures linearity of the entire measuring range regardless of the tilting direction of the component being measured. Processor functions Form Talysurf uses powerful software to combine data generated by vertical movement of the stylus with data collected from the linear scale and reading head in the horizontal traverse unit. The result is a grid array of as many as 120,000 data points, each with unique spatial characteristics.
Calibration is programmable and essentially automatic. A positioning stage is used to manually locate the crest of the ball in the 'Y' axis. Cresting in the 'X' axis, movement of the traverse to its start position and the actual measurement are all automatic.
calibration over a ball checks gauge range, linearity, stylus condition and processor functions
The result is a true system calibration - all elements have been checked: • Arcuate stylus motion error • Gauge non-linearity • Stylus tip geometry • Instrument stability • Traverse datum and data logging
measure dimension, form and texture at once with a single traverse over curved surfaces
• Gauge / stylus mechanical stiffness • Processor functions

µltra Software µltra 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 conflicts typically created by third party or after market software packages. Mechanical performance is optimized by use of patented software routines and proprietary calibration techniques.
Compliance with international standards Whatever the parameter and wherever in the world it happens to be measured it is guaranteed to be correct. µltra also adheres to industrial metrology disciplines as practiced by leading manufacturers around the globe.
• Mechanical functions positioning and speed of all axis movements
• Calibration routines are easily integrated into corporate ISO 9001 procedures
• Administrative functions user preferences, data storage and retrieval
• Artifacts used for calibration can be identified and referenced to certification date
• Analysis functions application of filters and constants, calculation of results
• Calibration history regarding operator, artifact and date is automatically stored
• Display functions screen graphics, customized templates, print commands Compatibility µltra was designed to be fully compatible with older Taylor Hobson data file formats, thus enabling re-analysis and comparison of old data. It also has a programmable facility for the simple export of results to standard packages such as SPC and ExcelTM.
µltra powers Talycontour dimensional contour measuring systems
• Calibration is recommended whenever the stylus arm is changed. To simplify this process all stylus arm configuration dimensions are stored for easy recall Industrial strength interface
µltra powers Talyrond roundness and cylindricity measuring systems
Although written with familiar Windows conventions, µltra has the look and feel of a machine tool interface. Commands are direct, purposeful and driven by intuitive logic. Perhaps for the first time in metrology the computer is a bridge instead of a barrier between operator and instrument. µltra simplifies training and eliminates the need for dedicated, single system operators
12
Form Talysurf Series 2 Multi-instrument architecture
Automation for consistency and safety
µltra takes full advantage of client/server technology and is designed to drive all Taylor Hobson hardware devices including Form Talysurf Series instruments and Talyrond roundness systems.
Saving time is just one benefit of automation. Horizontal, vertical and tilting movements are programmable to provide consistent start positioning. Minimizing operator intervention also minimizes damage caused by mishandling.
• Operators familiar with µltra can easily operate multiple instruments • No need for dedicated, single instrument operators • Transfer of knowledge is simplified when operators are promoted or transferred • Network ready for central data storage and output to network printers
• Automatic start positioning location of the stylus on the component is repeatable and correct • Automatic measuring runs every step is performed in the right sequence in the right location • Automatic analysis routines filters, evaluation methods and parameters are always identical
Comprehensive analysis µltra includes as standard everything important to the measurement of surface finish. All the basic roughness and waviness parameters are here along with advanced analysis tools that are either standard or optional depending on system configuration.
automation safely positions the stylus with horizontal, vertical and tilting movements
• Contour analysis • Dual profile • Aspheric form • Feature exclusion tool • Feature zoom tool • Form analysis • Point to point distance • Radius measurement • Angle measurement start and stop positions are programmable to prevent damage to the stylus
multiple locations on a component can be measured within an automatic routine

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

In figure 1. the elements marked in pink have been excluded. An LS Line form fit analysis is applied to the remaining sections to determine total profile deviation (Pt).
In figure 2. the "curtains" are closed on all but one arcuate section of the profile which consists of approximately 15,000 horizontal data points.

Form Talysurf Series 2 Dimension, Form, Roughness and Waviness Analysis Although µltra can be provided without Form Analysis this powerful feature is recommended whenever a component has curved or inclined features or otherwise 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
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.

In figure 3. errors of form along the radius are shown clearly. A perfect sphere would appear as a straight line and the Pt value would approach zero.
In figure 4. the roughness along the radius is displayed at high magnification. Typical roughness parameters have been calculated using conventional filters.
Figure 3.
Figure 4.
15
Inclination and alignment A 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 over the entire range has been considered in the calibration process. µltra software handles the manipulation and analysis of the data quickly and easily. In this example the zoom method has been used to isolate the inclined feature of the component. In addition, the feature has been aligned to horizontal and can now be used as a reference datum for point-to-point distance measurements and determination of surface tilt, intercept and pitch.

In figure 5. waviness parameters on the horizontal surface have been calculated using conventional filters. The inclined surface may also be assessed independently.
In figure 6. roughness parameters on the inclined surface have been calculated using conventional filters. The horizontal surface may also be assessed independently.
