A CNC-based vision metrology system offers numerous advantages in precision measurement and quality control. One of the primary benefits is the high precision and accuracy these systems provide, as CNC control ensures consistent, repeatable measurements with sub-micron accuracy, minimizing human error. The system is automated and programmable, reducing dependency on operator skill and allowing for batch processing. The use of non-contact measurement, through cameras makes it ideal for fragile or flexible parts, preserving the integrity of the components being inspected.
These systems are also much faster than traditional methods, capturing numerous data points quickly and providing real-time feedback, which is particularly beneficial in high-throughput production environments. Additionally, CNC-based vision metrology enables 3D measurement capabilities, thanks to multi-axis control, which allows the system to measure complex parts from different angles. Advanced software integration provides robust data analysis and reporting, while features like real-time data collection support statistical process control and ongoing quality improvements.
The flexibility of CNC vision systems is another key strength, as they can measure a wide variety of parts, sizes, and geometries, making them versatile for different industries. Moreover, they require less setup time, with quick changeovers between different parts and minimal fixturing due to their non-contact nature. Overall, CNC-based vision metrology systems enhance productivity, reduce labour costs, and lower inspection costs over time, making them highly cost-effective in environments where precision and quality are paramount.
A modern version of these systems is the AVR 400 from Starrett.
A stage travel of 400mm x 300mm x 200mm in the XYZ axes, with stage travel speed capability of up to 120mm/sec. Coupled with the CNC capabilities and a complete line of zoom and telecentric lens options, the AVR400 gives users the option to measure a broad range of part sizes, or larger runs of multiple parts, while simultaneously reducing inspection time. All without having to compromise accuracy.
It features full CNC XYZ positioning or motorized manual positioning using a pendant with joystick and track ball, MetLogix™ M3 software , Video Edge Detection, Pattern recognition capability for automated inspection, Colour digital video camera, Touch probe compatible for optional multisensory capability, LED substage and ring light illumination.
Starrett vision products are available in the UK and Europe from Optimax.
