Measuring software for industrial usage

Strong and flexible

"We at sigma3D develop modern software for tomorrow's measurement technology in a dynamic team with agile development methods."

Special metrological applications and the programming of simple measuring sequences in interaction with modern 3D measuring systems are our strength. We develop individual and smart software solutions from software-supported form and position tolerance, to the classic steel industry and the automotive industry. This includes the classic desktop application as well as centralized client-server applications with modern web technology! Finding optimal and economical solutions for your individual measuring task is one of our strengths. We would be happy to work with you in an initial workshop to create a measurement concept and carry out an initial requirements analysis.

Contract development

The continuous casting plant supplier SMS Siemag has been relying on sigma3D's measuring competence for the alignment of steel mill components for years. From this cooperation the idea was born to create a user-friendly software for the steel mill personnel at the end customers of SMS Siemag.

The correct alignment of moulds and segments has a great influence on the quality of the slab. Alignment errors of a few tenths of a millimetre can lead to quality defects or malfunctions in critical areas. The measurement objects in this working area are usually very large, unwieldy and difficult to see. The laser tracker is predestined for these high demands on measuring accuracy and volume. It is a universal measuring tool with an extensive range of functions that requires well-founded specialist knowledge to be fully mastered. With the standard software of the laser tracker the measuring tasks of the alignment of moulds and segments are difficult and only accessible to qualified personnel. The measurements are also associated with many conversions of measured values. As an example, only the determination of possible lining plate thicknesses should be mentioned here. These general conditions prompted SMS Siemag to develop its own measurement concept, which - with the laser tracker in focus - covers the following objectives:

  • Increase accuracy and reliability
  • Simplify and shorten the measuring process
  • a continuous computer-aided measuring process
  • universally applicable in the complete plant
  • Time and material savings in the workshop

Conclusion:

Because the alignment work is supported by specially developed software, this task can be performed by the plant operator himself after a short training period. The entire measuring and alignment process is significantly more error-tolerant. In addition, human error possibilities are considerably reduced. With the previous measuring methods, a large number of additional error influences occurred during the alignment of the segments within the segment alignment stands. These can be reduced to a minimum by using the software and the laser tracker.

A specialist for the production of large steel pipes based in Germany produces longitudinally welded, thick-walled steel pipes for pipeline construction. To check these tubes, both tube ends are measured using laser trackers in order to document compliance with the manufacturing tolerances.

Therefore the company sigma3D GmbH developed the software TubeSoft, which is able to control the FARO Laser Tracker ION and Vantage and guides the user through a clearly defined measuring process. The elements to be measured or calculated are defined by a default file. TubeSoft reads the default file and guides the user through the measurement procedure defined in the default file. Finally, TubeSoft creates a result file with all measured values as well as the parameters required by the specification file.

In addition, TubeSoft includes an expert mode that allows numerous settings (such as tracker type, exchange folder, measurement step sequence, etc.) to be password protected.

For a well-known manufacturer of industrial robots, modules for the control of the measuring devices for the measurement of absolute robots were provided. For automatic robot measurement with Laser Tracker, at least three reflectors must be measured using the camera function of the tracker. The approximate position of the reflectors is known from the robot position and the tool to be measured (+- 50mm). The xyz position with respect to the tracker coordinate system is to be returned as the result for each reflector.

For verification, a reflector is dynamically measured during robot movement and compared with the target values.

For this purpose sigma3D GmbH implemented the predefined sensor interface for the Faro Laser Tracker Vantage. The interface is implemented under C# (Framework 3.5). In addition, the implementation is secured with unit tests (MSTest).

The robot cell calibration, the so-called base measurement of industrial robots (e.g. KUKA, FANUC, ABB, ...), is carried out in precision applications using a 3D measuring system. The 6D reference between the robot and the fixture is produced. Standard measurement programs are usually used to determine the 6D parameters. sigma3D has developed its own software module for the efficient measurement of robots, which is used as an add-on to the existing OpenSource software OpenIndy.

In the RobCalc software, both the measurement and the calculation and evaluation process are mapped up to the customer-specific documentation (e.g. according to Audi guidelines for robot measurement).

With the software, robot bases can be determined faster and more accurately than with the available standard methods.

Strong and flexible

We develop individual and smart software solutions from software-supported form and position tolerance, to the classic steel industry and the automotive industry.

This includes classic desktop applications as well as centralized client-server applications with modern web technology.

We combine our unique expertise in mobile measurement technology with agile software development.

Finding optimal and economical solutions for your individual measuring tasks is one of our strengths.

In an initial workshop we would be happy to develop a measurement concept together with you and carry out an initial requirements analysis.

We offer a complete solution from the development of the measurement concept to the automated generation of protocols.

We are also passionate about developing central data management and web standards-based networking.

...are a big and important topic for us.

Keywords such as "fourth industrial revolution" or "industry 4.0" are not just keywords for us.

We take technologies from different areas and create future-oriented solutions for your company that are adapted to your individual requirements.

For our own engineers we develop an open source software for the solution of industrial measurement tasks with a laser tracker.

The software is not designed for a specific task, but rather a general solution for different tasks.

From the measurement of industrial robots to the alignment of machine parts, OpenIndy can be used.

Optimized program parts are developed for certain tasks.

Industrial robots can be measured much more accurately and quickly with OpenIndy.
