Production Control

Optical inline measurement technology for 100 percent production control

For production control, Fraunhofer IPM develops optical systems and imaging methods which can be used to analyze surfaces and 3D structures in production and to control processes. The systems measure fast and accurately so that small defects or impurities can be detected, even at high production speeds. This means that 100 percent production control in real-time is possible against the backdrop of the fourth industrial revolution.

A wide range of methods is used, including digital holography, infrared reflection spectroscopy and fluorescence methods, combined with fast, low-level image and data processing. The systems are used in applications such as forming technology in the automotive industry and for quality control in medical products.

Our 2D and 3D inline measuring systems supply high precision measurements in real-time and under hardest production conditions, for example for controlling sensitive production processes. This is achieved by a combination of optical measuring techniques with extremely fast data processing.  Our turnkey systems for surface analysis use fluorescence measurement techniques as well as infrared reflection spectroscopy and laser-induced breakdown spectroscopy. In systems engineering Fraunhofer IPM relies on its long-standing experience in optical units, image recording and image processing.

We offer the following services relating to all aspects of production inspection

  • Prototyping and development of customized complete solutions
  • Commissioning and maintenance of the inline systems on-site
  • Technology transfer and training
  • Consultancy for and assessment of technology
  • Feasibility studies and suitability tests
  • Contract measurements and measurements at customers' premises
  • Workshops

Focus topics

 

Data evaluation

Part of high-performance measurement technology is an equally efficient data evaluation. We support you in developing strategies for handling multiple data streams − and generate maximum benefit from your measurement data.

 

 

Systems expertise

We develop optical measurement and inspection systems for reliable use in production. In this, we combine our comprehensive know-how in optical technology with an eye for the specific conditions on site. Our numerous references from very different industries speak for our success.

 

Collaborating robotic systems

To perfect the interaction between state-of-the-art sensor technology and handling, Fraunhofer IPM is developing innovative approaches and products. This includes the establishment of modern, standardized interfaces, such as OPC-UA.

 

Industry 4.0

Connecting the real and the virtual worlds creates new opportunities while leading to completely new demands on modern production. We meet these increased demands with the advantages offered by optical measurement technology. Our new measurement and test procedures enable flexible, inline-capable, 100 percent-reliable production control.

 

App development

There are many options for either performing optical measurement and test procedures on a smartphone, or for combining both.

Fraunhofer IPM develops applications for mobile end devices on request.

HILaM research project / 23.4.2024

Controlled laser drilling of microvias

In the production of printed circuit boards (PCBs), micrometer-diameter vias – known as microvias – are drilled through multilayer PCBs. Lasers can drill through these structures with high throughput and micrometer precision. A measurement technique based on laser-induced breakdown spectroscopy (LIBS) is set to check the quality of the holes inline and control the process.

 

Press release Hannover Fair / 11.3.2024

Inline quality control during cold forming of precision parts

An optical inspection system inspects the geometrical dimensional accuracy and surface quality of cold-formed components during production for the first time – to within a few hundredths of a millimeter. This technology allows components with low manufacturing tolerances to be produced by forming rather than energy-intensive machining.

Quantum magnetometers detect smallest material defects at an early stage

As part of the QMag project, two teams at Fraunhofer IPM have successfully developed and employed optically pumpled magnetometers, OPM, for materials testing and for flow metering.
