Method & Evidence

AimTo develop and validate a vision-based measurement system for real-time quality control in high-pressure die casting to reduce defect rates and improve process stability.
MethodExperimental validation and comparative analysis.
ProcedureA vision-based measurement (VBM) system using a COGNEX IS7600M camera and image processing techniques (Hough Transform, Sobel edge detection) was developed. This system was integrated into a die-casting process following the RAMI 4.0 model. Critical dimensions of automotive clamping forks were measured in real-time. Measurement uncertainty was assessed, and Statistical Process Control (SPC) charts were implemented. A Failure Mode and Effects Analysis (FMEA) was conducted to evaluate cost savings.
