Machine vision systems in the metal industry

Metalworking (turning, milling, drilling machines)

Modern CNC machines require precise setup and continuous tool monitoring. Machine vision systems automate critical machining operations: from part alignment to tool wear monitoring. Cameras and controllers integrate with CNC equipment, ensuring fast non-contact setup and real-time monitoring. This improves machining accuracy and reduces risks caused by human error.

Capabilities
  • Automatic workpiece alignment — cameras determine position and orientation, transmitting coordinates to CNC in seconds, eliminating manual measurements and setup errors;

  • Tool wear monitoring — optical inspection detects cracks, chipping, and excessive wear; the system notifies the operator or stops the machine if critical;

  • Integrated quality control — in-line inspection of dimensions, geometry, and surface condition without additional manual steps;

  • Positioning and loading — guiding robotic arms for precise workpiece placement in chucks and fixtures.

Implementation Example

Synetra Iris for CNC turning machines.

What the system does
  • Verifies dimensions: length, diameter, chamfers, grooves;

  • Detects surface defects: scratches, chips, scoring;

  • Confirms correct machining operations (threads, grooves, etc.);

  • Commands the robot to sort parts (pass, recheck, scrap);

  • Saves photos and measurement logs to MES.

Result
  • 100% elimination of manual control;

  • No missed machining operations;

  • Geometry stability improved by 35%;

  • Labor savings — minus 3 operators per shift;

  • Complaints on geometry reduced to <0.6%.

Casting, forging, welding, and heat treatment

Heavy manufacturing processes involve high temperatures, vibrations, and extreme conditions. Machine vision provides non-destructive quality control and supports automation under such challenges.

Capabilities
  • Defectoscopy of castings and forgings — AI-driven detection of cracks, pores, cavities, and surface defects invisible to the human eye;

  • Weld seam inspection — checking geometry, continuity, and length; detecting undercuts, porosity, cracks, and missing welds;

  • Real-time weld monitoring — laser and video sensors track seam position, automatically correcting robot trajectory;

  • Thermal process monitoring — IR cameras track heating/cooling during forging, welding, and heat treatment for consistency.

Implementation Example

Synetra Iris for casting and welding quality inspection.

What the system does
  • Inspects castings or welded joints from multiple sides;

  • Detects cavities, cracks, undercuts, porosity, slag;

  • Compares shape and size to CAD/3D models;

  • Verifies weld seam quality and continuity;

  • Classifies defects and sends data to MES/QC.

Result
  • Up to 97% defect detection without human operators;

  • Hidden defect rate reduced by 60%;

  • 100% elimination of human error during inspection;

  • Stable heat treatment control;

  • Internal rework after welding reduced to <0.8%.

Geometry, dimensions, roughness, form, and assembly control

Machine vision replaces manual inspections with precise, automated, 100% part verification.

Capabilities
  • Dimensional inspection — measurement of diameters, radii, angles, distances with micron-level accuracy;

  • Form and tolerance control — comparison against CAD models or references, detecting warping, bending, ovality;

  • Surface quality and roughness — non-contact inspection for scratches, dents, grooves, and micro-defects;

  • Assembly verification — ensuring all components are present and correctly positioned, preventing mix-ups and incomplete assemblies.

Implementation Example

Synetra Iris at an automated assembly line.

What the system does
  • Measures holes, chamfers, protrusions, and critical distances;

  • Checks form: straightness, parallelism, perpendicularity;

  • Detects missing or misaligned parts;

  • Performs optical roughness inspection.

Result
  • Dimensional accuracy up to ±0.01 mm;

  • Assembly defects reduced by 85%;

  • 100% detection of missing elements;

  • Inspection time per unit reduced 4x;

  • Repeatability of quality increased by 40%.

Automated tracking, marking, and traceability

Traceability is essential in metallurgy and mechanical engineering. Machine vision ensures accurate marking, product identification, and digital history recording.

Capabilities
  • Optical Character Recognition (OCR) — recognition of alphanumeric codes and serial numbers, even with low contrast or contamination;

  • Barcode and DataMatrix scanning — high-speed reading of 1D/2D codes, even multiple items in motion;

  • Movement and history tracking — digital passport for each part through all production stages;

  • Verification and aggregation — compliance check between item and packaging codes, preventing shipment errors;

  • Automated reporting and statistics — seamless integration with MES/ERP for production analytics.

Implementation Example

Synetra Iris at a packaging and logistics area.

What the system does
  • Reads laser engravings, DataMatrix, QR, and serial numbers;

  • Validates readability and correctness;

  • Matches marking with part specifications;

  • Scans packages automatically without manual effort.

Result
  • 100% elimination of marking errors;

  • Inventory registration speed increased 6x;

  • Full real-time product traceability;

  • Sorting and duplication errors reduced by 80%.
