This study introduced a new design of a low-cost customized A-scan Non Destructive Testing (NDT) unit using microcontroller-based scanning motion. the scanning unit from previous research has limitations in scanning envelope area and ability of detection. It can only detect large defects. To solve the limitations mentioned above, the purpose of this study is to develop a device with lower cost, more appropriate size of scanning envelop area, and ability to detect internal layer defections. the mechanism of this machine is achieved by using 3 NEMA 17 bipolar stepper motors for the movement of every axis. MATLAB is used in this machine for the purposes of signal acquisition, signal analysis and to control the linear motions. Since this machine is small in size (40cm x 27cm x 72cm), it can be used for small scale testing and analysis. As compared with current product, this machine is more portable and affordable. Thus, it is more convenient in the areas of research and education. the contributions of this machine is providing an affordable machine for advancement research field and enhancement quality inspection in manufacturing industries.
Key words: Non Destructive Testing (NDT) / scanning motion / signal acquisition / signal analysis
