Inline Metrology: Enhancing Manufacturing Precision in Real Time
In today’s highly competitive manufacturing landscape, maintaining quality while maximizing productivity is paramount. Inline metrology has emerged as a critical technology that enables real-time measurement and inspection directly on the production line. By integrating measurement systems into manufacturing processes, inline metrology ensures tighter control, faster feedback, and reduced defects.
What is Inline Metrology?
Inline metrology refers to the use of measurement technologies embedded within a manufacturing process to continuously monitor dimensions, surface quality, and other critical parameters of products as they are being produced. Unlike traditional offline inspection, inline metrology eliminates the need to remove samples for measurement, enabling immediate corrective actions and minimizing waste.
Key Technologies Used in Inline Metrology
