• Overview

    We are your partner for the design and implementation of sophisticated technical and mathematical software. Our team of mathematicians, physicists, electrical engineers, IT specialists and mechanical engineers is an ideal mixture of specialists which allows us to successfully realize complex projects on a high scientific level within a very short time. Our employees are thoroughly trained, have excellent university degrees as well as an outstanding knowledge of IT.

    We develop basic mathematical procedures for the calibration, correction and operation of the corresponding Carl Zeiss IMT measuring machines. This wide range of tasks comprises the theoretical basics of dimensional metrology and the creation of complex software systems.

    Many new methods for dimensional metrology have been developed in the Carl Zeiss innovation center for metrology. For example, the kinematic analysis and correction as well as the associated software packages for the ScanMax presented by Carl Zeiss in 1995 were developed here.

    We have set unique standards in gear measurement technology. The mathematical modeling of gears and the acquisition of measuring data for a complete theoretical model have also been developed here. In the meantime, the Federal Physical/Technical Institute has included the corresponding algorithms in a reference software. We develop and distribute our INVOLUTE product to all coordinate measuring machine manufacturers. INVOLUTE is based on a new theoretical approach for gear measurement. Additional modules for the evaluation of worms, toothed racks and rotors are available upon request.

    Many renowned coordinate measuring machine manufacturers use our best-fit library certified by the Federal Physical/Technical Institute (PTB). It makes it possible to determine geometric default formula elements as Gauss, zone, circumscribed and inscribed features with high performance even for large data volumes.

  • Bestfit


    Our new patented best-fit method makes it possible to determine form and position errors of free form surfaces. It is even possible to reproduce smaller bending radii by means of special methods for local geometry adaptation. Furthermore, admissible errors of the nominal geometry can be taken into account. Thanks to the elastic model, it is now possible to easily represent a large number of previously unsatisfactorily solved best-fit problems.


    One of these methods is, for example, used for the efficient evaluation of measurement data of turbine blades. In addition, the BladePro software package allows you to determine a large number of blade-specific parameters. BladePro is used for the production as well as for the maintenance of aircraft engines and industrial turbines.

  • Calibration methods

    Development of calibration methods

    We have many years of experience in the development of calibration methods for sensors and complete components. The methods developed by us are used on almost all coordinate measuring machines and sensors of the company Carl Zeiss Industrielle Messtechnik GmbH. The ScanMax is one of the most kinematically demanding machines. The systematic errors are completely corrected on the basis of its physical model. In contrast to traditional methods, a more precise calibration with less effort is possible.

    Furthermore, we have developed specific calibration methods for other measuring machines and machine tools. This includes methods for our roundness measurement and the calibration of measuring systems in machine tools and form testers.

  • Software

    Software development and consulting services

    Apart from our own products, we also develop customer-specific software starting from complete systems to special components and libraries. Our team consists of mechanical engineers, physicists, mathematicians and IT specialists and is in a position to analyze and realize complex and high demands. We will be glad to advise you regarding the following topics:

    • Software architecture
    • Creation of reliable development processes
    • Reasonable use of current technologies

    For 15 years we have been addressing ourselves intensively to software developments with the aim to realize stable and user-friendly software. From the beginning, we have been attaching great importance to development processes which have been firmly represented for a long time now. The quality and usability of the products are the first priority with the aim to permanently offer flexible and expandable architectures. Our best-fit modules can be found in the software of all renowned coordinate measuring machine manufacturers and many of them especially in the products of the company Carl Zeiss Industrial Metrology. Well-known automobile and machine tool manufacturers also belong to our customers.

  • Form measurement

    Form measurement in the machine tool

    • Roundness measurements without measuring machine?
    • No precise bearings?
    • Measurement during the production process?
    • Still precise?


    Our patented method for the measurement of roundness, diameters and coaxiality requires a relatively simple arrangement of sensors. The measuring signals are detected online and evaluated by means of a complex software package. The results are immediately shown in a formplot. Once the calibration of the device has been completed, the diameter can also be determined. And by the way, you can produce the calibration standards yourself as they do not need to be very precise. However, it is important to measure the standard on a measuring machine. These data will then also be calculated in the software.


    It is also possible to determine the shifting of the rotary axis during the rotation of the workpiece. This produces a virtual bearing. An additional sensor immediately measures the runout error.


    The reference-free roundness measurement and diameter measurement on rotating workpices is performed with three or four transducers which probe the workpiece from different angles. The circular form errors as well as the superimposed movement of the rotary axis are evaluated at the same time.
