Use Cases for Visual Quality Control with UNITY

Milled Surface Inspection

Achieving consistent and accurate control of these surfaces requires overcoming the difficulties of illuminating irregular contours and effectively capturing the fine details that are often affected by reflections, shadows and surface topography. The development of reliable inspection methods for milled surfaces requires innovative techniques that mitigate these complexities and provide comprehensive evaluation without compromising accuracy.

Pressed Metal Inspection

Achieving accurate quality control of these surfaces requires methods to distinguish surface irregularities from the intended structural elements and to assess any deformations. The assessment of pressed metal surfaces is further complicated by their reflective nature, which causes problems in detecting defects due to glare and reflection. The complexity lies in detecting imperfections hidden in the geometry, which requires advanced imaging technologies capable of accurately identifying subtle defects.

Paint & Coating Inspection

The inspection of painted and coated surfaces is complex, as defects must be accurately identified while taking into account differences in the quality, colour and texture of the coating. The inspection process has to cope with issues such as hidden defects within the coating, irregularities in application and environmental influences, which require specialised methods to ensure comprehensive defect detection despite these variables. In addition, reflective properties and different paint and coating textures add another layer of difficulty in accurately identifying defects.

Material Applied to Glass Inspection

The inspection of materials applied to glass requires specialised inspection methods due to their transparency, which makes defects less visible. Problems include irregularities in thickness, embedded foreign particles, air pockets and wavy parts of the material. Manipulation of the colour spectrum through advanced camera technology helps to highlight imperfections that would otherwise be difficult to discern, providing comprehensive defect detection on transparent surfaces.

CNC Turning Inspection

Inspecting CNC turned surfaces requires a specialized approach due to their reflective cylindrical exteriors that create challenging reflections and complicate defect detection. The complex shape of these surfaces requires image capture from multiple angles to accurately cover the entire surface. Advanced camera systems are used to eliminate reflections and shadows, enabling accurate detection of defects, especially when identifying imperfections such as porosity, scuffs, scratches or dents. This innovative technology ensures careful identification of defects and contributes to consistent quality control in production.

Internal Surface Inspection

Inspecting internal surfaces presents unique challenges due to limited space, light constraints and complex part geometry. The deployment of miniaturized boroscopes enables detailed inspection and identification of defects such as irregularities, scratches or hidden imperfections within complex parts. These images create a comprehensive map of the internal surface, facilitating accurate defect detection and increasing the efficiency of quality control processes in manufacturing.
