This operator workflow, in difference to the basic component cleanliness workflow, uses a predefined Intellesis object classification model for the particle type differentiation. Depending on your specimen, retraining of the object classification model might be necessary to adapt the particle type differentiation to your needs.

The training of object classification models requires licensing of the AI Toolkit.

Step 1: Technical Cleanliness Standard Selection

Provides a default standard for TCA that shall be used for the analysis: VDA 19.1 Extended Analysis - Free Analysis. Other standards are available.

  1. Select the relevant standards, see Technical Cleanliness Standard Selection Tool.

Step 2: Input Form

In the Form Selection tool, an input form is provided. The specimen form is part of a loop. This step is iterated with Continue until the last loop iteration is reached. The specimen number increases automatically by 1 with each iteration. Exit Loop activates the next step.

  1. To choose the corresponding customer, in the Customer/Supplier field, click in the table to add the selected customer data.
  2. The form is displayed in the report.

Step 3: Load File

Loads images from the file system.

  1. Load one or more image files to the gallery.
  1. The image will be loaded to the Image view. The number of loaded images determine the number of workflow iterations of the following steps. Each iteration finishes with the report step before the next iteration starts.

Step 4 Particle Segmentation

Extracts objects from the background by applying the pre-defined relative threshold range.

Use the pre-defined settings for the image segmentation.

Step 5: TCA Standard-Specific Settings

Configures specific parameter for the standard based calculation.

  1. Select a membrane filter type you want to use for particle analysis. You have the following options:
    - Mesh Membrane Filter (component cleanliness)
    - Foamed Membrane Filter (component and oil cleanliness)
    - Others (oil cleanliness)
    Default: Foamed Membrane Filter.
  2. Add values to the desired normalization parameter, if required.
  3. Select how many of the largest particles per type you want to add to the report. The coordinates of all pre-selected particles will be added to the Position list with EDF.
  4. If the Equivalent Spherical Method (Components) tool is part of your workflow, check if you need to adapt the Reference Area.

See TCA Standard-Specific Calculation Workbench

Step 6 Size Distribution (Live)

Shows the absolute and normalized results of the particle size classification and approval status (if defined in standard template).

  1. Inspect for the selected standards the results per particle type and overall statistics.
  2. Change, if required, the particle type and exclude artifacts. Use the filter functions and approval display for rapid particle inspection.
  3. Conduct particle revision using the Edit view and retrieve particles in live mode.

See Size Distribution View.

Step 7: Position List with EDF

Performs automated EDF image acquisition on selected particles.

In general no further action is required.

Step 8: TCA Report

The TCA report is displayed for each specimen. You can adapt the report. To do so, configure the following settings:

  1. In the Template Selection tool, the default report template is selected.
  2. In the Chart Selection tool, select a particle counting result (absolute or normalized), one or more chart types, and one or more particle types. Select System Properties to have the system properties displayed in the report.
  3. In the Gallery Setting tool, set the image count per row.
  4. Click Apply to save your settings.
  5. The adapted report is generated.

After performing the workflow, you have the following options:

  • Save and Close
  • Save and Repeat
  • Close Without Saving
  • Repeat Without Saving
