Abstract
An impact testing apparatus and process are provided. The apparatus comprises a thickness verifier to measure the thickness of each specimen. The apparatus further comprises a notcher and a notch verifier which are operative to first cut notches in a test group of specimens and to subsequently verify the accuracy of the notches. The apparatus further comprises a robotic gripper to sequentially deliver specimens to a vise for impact testing. The impact tester of the apparatus is operative to automatically assess the impact on each specimen. Additionally, the impact tester comprises optical sensors to assess the type of break of each specimen subjected to the impact test. A control unit receives input data from the various components of the apparatus, analyzes the data and prepares test reports.
