Digital Surf introduces Advanced Contour software

The Mountains Surface Analysis Business Unit of Digital Surf has released a software module for controlling the dimensions of profiles measured on component surfaces.
Advanced Contour, which is part of the Mountains surface analysis software suite, will be shown at the Control International Trade Fair for Quality Assurance at the Stuttgart Exhibition Centre (Hall 3, Stand 3518) on 5-8 May.
With an icon-based user interface, a full set of metrological functions, a graphical display of form deviations, automatic quality report generation and the ability to export results to quality management systems, it is said to ensure that contour analysis is accurate and as straightforward and fast as possible.
Running under Windows XP and Vista, the software is designed for integration into form measurement instruments, including those working on the nanometre scale and for use in any research or production facility.
Profiles are segmented into geometrical elements whose dimensions are evaluated automatically.
An automatic matching process superimposes the nominal form on the measured profile, making it possible to display form deviations graphically and calculate form deviation parameters.
Measurement data can also be compared with a nominal form in DXF format output by a computer-aided design (CAD) system.
The quality report is built automatically in the background as the user works.
It includes a full table of results, listing the values of dimensions and parameters, their tolerance limits and their pass/fail status.
The full analysis history is stored and can be converted to a text file to assure full metrological traceability.
A comparison of measured profile with nominal form shows magnified form deviations (green for within tolerance, red for outside tolerance).
Out-of-tolerance points on the profile are shown in red, facilitating the location and quantification of faults on the nominal form.
Profiles with large dimensional tolerances can be analysed using special tools based on construction lines, allowing the definition of intersection points.
This makes it possible to reposition elements correctly despite large dimensional or positional variations.
Other features include the analysis of 'gothic arches' for characterising raceways.
Advanced Contour documents can be used as templates for controlling series of measurements.
After a template has been applied to generate a document, this document can be modified at any time and all numerical values affected by a modification are recalculated automatically.
Digital Surf is a surface metrology solutions provider.
