CAD Comparison on the Cloud

HPC-Competence Center

Arctur prides itself in not being just another HPC infrastructure provider, but rather one which always provides personal support even to users which are not so knowledgeable of HPC, so ensuring that every HPC project achieves or even surpasses user expectations. Their motto is “More than just HPC.” As an SME, they understand the issues that other SMEs face when dealing with HPC.

How HPC makes the difference

With the help of HPC, the processing time of quality checks at Stellba is being reduced to less than 20 minutes.

This success story is an outcome of CloudFlow project*.

Checking the quality and accuracy of a manufactured part against the ‘as-designed’ status of the corresponding ‘nominal’ CAD model is a common process in industry. For this purpose, the machined part is scanned with a 3D acquisition device, e.g. a laser scanner, which results in several point clouds typically consisting of millions of measured, discrete 3D points. To determine where deviations between the CAD model and the point cloud exist, the two data sets need to be aligned and matched in a process called registration and distances between the closest points of both models need to be calculated.

With the help of HPC, the processing time of quality checks at Stellba is being reduced to less than 20 minutes saving more than seven person-hours of work. The ICT supported manual process containing error prone steps is being replaced by a validated software application that bridges domain barriers and enhances the achieved quality of the inspection. The operator at Stellba can now focus on the quality of the measurement and the produced parts while leaving most of the data processing to the new software application. In this particular case, shortening the elapsed time for point comparison quality checks increases Stellba’s capacity for taking on new projects.
