Many manufacturers find the use non-destructive testing equipment as quality control technique that is applied by different industries ranging from industrial to aerospace. With automated NDT, experts apply scanners and robots to increase the speed and repeatability factor of technicians. This helps in creating more precisely produced measurements. Automated NDT scanner requirements are must have to attain high quality control and precision measurements.
In this article, experts will differentiate between rotational axes, Cartesian scanners and articulated robotic arm system.
Automated Cartesian scanners
Typical scanners used in the NDT industry have Cartesian scanners that can be customized for their job specifications. Manufacturers intend these systems with highly accurate actuators, stepper or servo motors and optical encoder modules, which make them ideal and most suitable tools for real-time signal acquisition when axes moves.
They also offer automation with enhanced inspection speed, imaging capabilities, real-time signal processing, and scanning repeatability. To acquire such design characteristics, stringent requirements have to be imposed on the automation technology which is in use. Some of the requirements include – mechanical design for high positioning accuracy of all axes, the required real-time encoder monitoring, the integration of high-speed interface for speed data transfer rate, etc.
Articulated arm robots
Industrial robotic arms perform the same as human arm; the only difference is that the muscles got replaced with the precise articulated mechanical links. These links are connected to offer rotational movements and manipulate objects within a certain volume. These robots are recognized as a polyvalent and robust solution for several applications like welding, material handling, laser cutting, machining, and more.
Unlike Cartesian gantry systems, these articulated arms offer a system with advanced dexterity. These robotic solutions can assist in advanced NDT methods once they meet the basic standards of automated NDT testing, i.e. data acquisition, accuracy, repeatability, and precision.
Challenges to robot designing
A few advanced articulated arm robots are believed to have apt features to be applied for automated NDT systems. The interest of aerospace sector for robotic solutions is growing as per the reports. However, regardless of efforts made, several design challenges and inspection factors should be determined to achieve robotic designs that fit well for automated NDT inspection.
It is the motion control and data acquisition. To know more about these challenges in depth, you can talk to experts that are involved in non-destructive testing equipment usage. For sharing thoughts about this article, please make your comment below.
