Development and maintenance of cloud-to-machine layer for a leading dental MOS provider: Oqcam
* IoT & gateways architecture for a dental lab
Project delivered 2 automated Capability Sixpack pipelines, capable of clustering the input dataset into smaller subsets and performing capability analysis on each. Input dataset could be acquired either from external input or pulled from Minitab. Capability analysis could be performed and results can be plotted using either a custom pipeline or using Minitab’s functionality. Output can be placed into a dedicated folder structure and visualized in Minitab.
* Resulting Capability Analysis Sixpack – sample from custom CLI pipeline
Project scope was focused on validation of a new Werth TomoScope XS CT for the use in production. This was achieved via a series of step gauge measurements, calibrated with with Zeiss CMM with attached uncertainty estimation. During the execution of the project, an academic investigation on the effect of surface roughness, mesh filtering and outlier removal was done, resulting in a custom software package developed for the purpose of data ingest and visualization, as well as a custom procedure for estimation of the effect of certain factors (based on variability analysis).
* CMM physical filtering, step gauge & CMM measurements, CT measurements.
Fully integrated AI based process monitoring solution, accurately predicting a critical process parameter from the thermal camera and webcam input.
The solution was developed for Additive Manufacturing (AM) process, with the task of predicting printed part warpage. System runs on a single chip computer, and can acquire and process data from 2 sensors, perform complex image processing on the input data before feeding it into a AI model, gather predictions, and finally, render results in a developed GUI (which runs in a local server app).
* Project workflow.
Project developed a custom metrological ML software framework, capable of generating artificial point cloud measurements from confocal microscope data. Project involved manufacture of a custom measurement object, as well as measurement acquisition on Olympus Lext machine. A custom Variational Autoencoder (VAE) model with convolutional (CNN) encoder block was developed to perform reconstruction. Measurand was constructed as an ISO 2-point distance and finally, comparison of measurement results between real and generated data was given.
* Reconstructed confocal microscope step-height measurement.
Generation of Point Cloud measurements using a Stereo Camera. A custom continuous acquisition method and ICP based reconstruction pipeline (with different loss functions) had been developed, enabling full scene and/or measurement object reconstruction. Raw input point clouds, generated via disparity map from the camera, had been continuously accumulated, filtered for outliers, downsampled and finally, overlapped using an ICP algorithms with various loss functions (i.e. Tukey loss).
* Raw stereo camera single frame acquisition – disparity map based point cloud.
Project applied advanced Optical Character Recognition (OCR) ML models to extract critical information from mechanical CAD drawings. A separated image processing pipeline was implemented to extrapolate relevant ROIs as the input for the OCR model and group the drawing into separate components (Infoblock frame, GPS dimensions & tolerances, drawing frame etc.).
* Final output of the OCR pipeline.
Main project target was to develop a ML framework, capable of accurately predicting cutting forces in X and Y direction, from a 2D CNC machining simulation data. Extensive Data Mining system had been established, capable of parsing and merging complex simulation output into a usable dataset. Data was subjected to outlier removal (IQR and Z-score) and BoxCox transformations, before being fed into a custom MLP model. Final results achieved MAE of 0.8195 % when comparing to average load in X direction and 4.0187 % in Y direction.
* Deform 2D CNC simulation + resultant load prediction.
