ZeroTouch non-contact metrology platform

A non-contact 3D brake inspection system that measures complex geometries and performs defect detection.

Non-contact 3D Brake Inspection System

The ZeroTouch® brake inspection system is a non-contact brake inspection system that generates a 3D point cloud, providing manufacturers with real-time metrology and inspection data to optimize production processes, detect defects, and improve ROI.

Increases Accuracy

Increases Throughput

Detects Defects

ZeroTouch measured the entire part surface, generating a high-density, micron-level point cloud.

ZeroTouch executed the inspection plan in just 20 seconds versus the tactile methods, which took 1 minute.

ZeroTouch measured all surfaces in 3D and identified defects too.

Data Integrity and The Digital Twin, Part 1

Metrology is moving from the lab to the manufacturing line, which brings non-contact techniques, digital twins, and the integrity of point clouds versus discrete measurement data under increased scrutiny.

Data Integrity and The Digital Twin, Part 2

In the second installment of Data Integrity and the Digital Twin, we delve deeper into the value of big data, tactile and non-contact measurement errors, and the magic of mathematics.

Overcoming Challenges in High-speed Inspection Using Non-contact Metrology, Part 1

When product quality and throughput are vital, performing high-speed, quality inspections present unique challenges that require precision solutions.
