• A little 'magic' in the world's most modern press shop (Jan 20, 2024)

  For efficient production, all processes and components must be precisely coordinated. Time optimization is an essential factor. The scanning spray from AESUB proves that even the smallest adjustments can make a big difference. In the Smart Press Shop, a joint venture between Porsche and Schuler, AESUB saves valuable time every day.

  Smart Press Shop GmbH & Co. KG (SPS) was founded in 2019 as a greenfield project by Porsche AG and the Schuler Group. The aim of the joint venture is, among other things, to significantly increase the level of automation and digitization in the production of press parts through efficient and flexible manufacturing methods. 

  
  Since 2021, the production of press parts has been running in what is currently regarded as the world's most modern press shop capable of producing high-quality car body parts for all car manufacturers. Thanks to the high level of automation, even small batches are produced economically. 

  Production in the digital age
  All process steps from goods receipt to forming in the press line to delivery to the customer are recorded digitally. SPS can use the evaluated production data specifically to optimize the manufacturing processes. This includes reliable production monitoring and intelligent production control.

  Digital twins for all pressed parts
  The quality of the pressed parts is validated in the measuring center. For this purpose, the manufactured pressed parts are measured optically by means of 3D scanning and the digital twins are compared with the original CAD data. Here, it is important to act in a goal-oriented manner and to constantly discover and integrate new potential for improvement. This includes, among other things, the improvement and optimization of the 3D scanning process by sublimating scanning sprays.

  Process optimization in the measuring room - scanning spray for faster measuring processes
  Optimum scanning conditions are required in order to perfectly capture and digitize the pressed parts. As long as the surfaces of the pressed metal parts are shiny, it is hardly possible to capture the entire surface, as the scanner light is reflected by the surface. To prevent reflections, the components are first matted with a scanning spray. The Smart Press Shop uses the AESUB scanning spray. When applied, the spray creates an extremely thin white layer of temporary coating and thus optimal condition for 3D scanning.

  Better measuring results without additional effort
  A major advantage of the AESUB scanning spray is that it evaporates completely and that the component therefore does not have to be cleaned after scanning. This also significantly simplifies handling in the SPS measuring room. This is because the parts can be sprayed directly in the measuring cell. There is no risk of damaging sensitive equipment. Additional extraction systems are also not required, as the sublimating AESUB scanning sprays do not contain any pigments. "Spraying is integrated into normal handling processes without any noticeable time expenditure. It takes only a few seconds," explains Anja Zyla, team leader in the metrology department at SPS.
  The part is placed, sprayed and scanned. If the part corresponds to the specified CAD data, it can be returned to the production process or delivered to the customer directly after measurement - without being cleaned. This means less logistics, less transport, faster process flows. A time saving that is clearly noticeable at SPS.
   If conventional, non-sublimating sprays were used, the part would have to be cleaned or disposed of at great expense. " The time saved by using AESUB at SPS is enormous," says Anja Zyla. The entire measurement process becomes more reliable thanks to the meaningful results, and handling is easier. With AESUB, more parts are measured in less time. "Time is money and, in the end, it is machine hours that we can compensate with AESUB. Without any extra effort, we have a better measurement result," adds Anja Zyla, "AESUB is our little magic in the Smart Press Shop."

• Scanning chrome parts of a Ford Super Duty Truck (Jan 20, 2024)

  - Measure reflective car parts more quickly and effectively
  - Scanningspray temporarily dulls shiny surfaces
  

  Bumpers, radiator grilles or rims – in car construction, many components of high-quality bodywork are chrome-plated or coated with other shiny surfaces.  Though they gleam with quality, they are a challenge to optical quality controls. Because shiny parts can be hard to digitise.

  Even modern optical scanners reach their limit where shiny surfaces are concerned. Because the light beam from the sensor is not reflected diffusely, but in focus. This means the scanner cannot measure the surface. To achieve unambiguously usable measurement results, the surfaces must be pre-treated before scanning. To this end, the shiny parts are sprayed with a matting agent. The process is rapid and uncomplicated. Within a few seconds  a mirror-like part becomes matt and can be digitised without a problem.
  
  The actual spray process lasts just a few seconds
  While the spray process itself is quick, pre-treatment and post-treatment have taken their time up to now.  With standard sprays, the process has to take place outside the measurement area, as the mist of spray deposits on the surrounding area and could contaminate the sensitive measurement devices.  This means the object for measurement need to be transported back and forth between measurement area and spraying site.

  Even more laborious, however, is the subsequent removal of the spray coating from the components. Depending on the component size, shape and material quality, cleaning can take several hours. Often, full removal – for parts with deep structures or sensitive surfaces – is impossible, meaning the parts can no longer be used.

  Volatile scanning sprays facilitate and accelerate the pre- and post-treatment
  With the new volatile scanning sprays from AESUB, components can be directly sprayed on the measurement machine, meaning no time is lost to extra transport. The greatest time saving is in the sublimation, i.e. the independent evaporation of the spray coating. After a few hours, the matt layer is completely gone. This protects the high-quality measurement device and saves time spent in cleaning the objects. The evaporation time depends on the AESUB spray variant and can be between an hour and up to 24 hours.

  Scanning chrome parts of a Ford Super Duty Truck
  Recording chrome parts with a white-light scanner is a difficult measurement task, explains Curtis Blanchette from Rapid 3D Ltd, Calgary (Canada). The shiny surfaces make digitising the component geometry more difficult. The measurement provider Rapid 3D uses scanning sprays from AESUB to accelerate and optimise digitisation processes. For the measurement, the chrome radiator grille is dulled using an AESUB Scanningspray. Normally for this process, Curtis Blanchette states, the spray AESUB blue is used. As the part in question here is the radiator grille of a Ford Super Duty Truck, however, with a large surface area, the AESUB green spray in a container with a portable spray pistol was used. The spray process lasted approx. one minute. After one more minute the spray was dry, meaning the chrome parts were covered by an even, matt layer. Measurement points for digital recording were placed on the touch-dry surface. Now it was no problem digitising the radiator grille. After six hours, the applied layer had fully sublimed. The parts had returned to their original gloss and the measurement points could be easily removed.

  The evaporating AESUB scanning sprays contain no titanium dioxide and no further pigments. In contrast to pigment-containing sprays, the coating of AESUB sprays is touch-dry, making handling of the matt components much easier. The layer does not wipe off, meaning no undesired structures arise when it is touched.

• Automated spraying: Faster measurement of shiny objects (Jan 20, 2024)

  Automated matting of shiny and transparent parts
  Automation is progressing at breath-taking speed. Costs have to be lowered and capacities increased. In automobile manufacture in particular, this trend is clearly visible. And in optical measurement technology, too, processes are increasingly being automated. In spatially defined scanning boxes, 3D scanners mounted on robot arms rapidly and accurately digitalise the components in an extremely short space of time. However, automated measurement meets its limits when it is difficult or impossible to measure the dimensions of the components owing to their shape, size or material characteristics. These include transparent, reflective and uneven surfaces which hinder the entire optical measuring process and – if it is possible at all – often lead to distorted measurement results.

  Problematic: scanning of transparent and reflective surfaces
  With transparent surfaces, the light of the scanner shines through the surface which means that the surface structure cannot be captured.
  Similarly, with reflective surfaces, the scanner is also not able to scan the surfaces. Here, the ray of light is reflected not in a diffuse, but focused manner.

  A further problem comes from components with pronounced uneven areas. The walls of recesses cause reflections and lead to incorrect representations.

  Matting of the surfaces
  Transparent and reflective surfaces can be matted using scanning sprays. Using a newly developed spray, the AESUB scanning spray, a matt, white and homogeneous coating is generated in just a few seconds. As a result, the component’s surface become impervious to light and no longer reflects, which means that the objects can be scanned. Because the AESUB spray automatically sublimates, cleaning of the components after the scanning process – something which is time-consuming and/or costly – is no longer necessary.
  
  Automated spraying
  Using spray robots, the measurement of problematic surfaces is automated further: the matting is directly integrated into the automated digitalisation process. To do this, the component is arranged in the measuring cell and/or scanning box for the measuring process. Via a spraying mechanism, the

  AESUB green scanning spray is fed into the robot arm.  The robot arm travels along the path programmed for the digitalisation and, in the process, evenly sprays the component to be measured with the AESUB scanning spray. Depending on the component size, the entire spraying process lasts approx.  20 - 60 seconds. A white, homogeneous layer approx. 10 µm thick is generated, onto which reference points can also be applied without a problem. Subsequently, the digitalisation begins with a second robot arm on which the scanner is mounted and which travels along the same contours as the spray robot previously.
  
  Automatically sublimating spray, no contamination of the measuring environment, no cleaning

  The AESUB spray is free from pigments – such as harmful titanium dioxide – which are frequently used in conventional scanning sprays. Pigment-containing sprays inevitably cause contamination of the measuring environment. They put the user at risk and damage the component and also the sensitive measuring equipment. Because the AESUB spray evaporates automatically, no cleaning of the component or measuring environment is required. Unlike the pigment-containing sprays, the coating applied with AESUB sprays is touch-dry, which hugely simplifies the handling of the sprayed component.
