In robotic non-destructive inspection (NDI) applications, there are typically two different methods of inspecting a part: process to part and part to process. Each of these methods has their own advantages, especially for critical inspection of aerospace composite components, and is deployed in specific scenarios.
Understanding the relative value of each method can help you determine which is best for your particular application and why a robot integrator may choose one method over another.
Robotic Non-Destructive Inspection Methods: Process to Part
The process to part method is the traditional form of robotic NDI. In this method, the robot with various sensors is programmed to move around a fixtured composite part, essentially bringing the inspection process to a stationary part. This method is typically used for inspection of large parts.
The process to part method is beneficial when large parts are not easily moved around a facility. Sometimes, it is more cost-effective for a robotic arm to bring the inspection process to the part. Also, this allows for easy transition between different types of sensors in-process for 100% inspection of the part.
Robotic Non-Destructive Inspection Methods: Part to Process
The part to process form of robotic NDI is newer than the method described above. In the part to process method, a robotic arm manipulates the part to be inspected around a stationary sensor or series of sensors. This method of NDI is often effective for small components.
The purpose of part to process robotic NDI is to facilitate a higher volume of parts for inspection. When the part is brought to the inspection process, robots can manipulate multiple parts for inspection without the intervention of an operator for increased productivity.
Each method of robotic NDI – part to process and process to part – is deployed in specific scenarios and has unique advantages, depending on the type of parts that need inspecting.
Robotic NDI can be a major source of efficiency, quality and productivity. Regardless of which method is used, robotic NDI work cells for part to process and process to part inspection are innovative solutions for more productive and accurate inspection.
