roboTest H: robotic testing system for impact tests on metal specimens

The reproducibility of test results is an important aspect of impact testing on metal Charpy specimens. To minimize operator influence and maximize accuracy, Zwick has developed a robotic testing system for pendulum impact testers. The system can perform Charpy tests to established ASTM and ISO standards on 55 x 10 x 10 mm specimens.

Zwick’s roboTest H robotic testing system performs automated room temperature Charpy impact tests to be performed. A major advantage is significant improvement in reproducibility enabled via pneumatic actuators that deliver 3-way alignment of the specimen on the support. The result is the elimination of operator error due to improper positioning of the test specimen. The complete system consists of the roboTest H robotic testing system, a magazine that houses up to 20 specimens (stacking height 200 mm) and a 450-joule pendulum impact tester.

In preparation for the test, specimens are inserted into a magazine slide-carrier and positioned in the robotic testing system. After the magazine has been placed in the robotic testing system, a button is pressed to start the individual test. Within five seconds the specimen is transported to the support via a positioning arm centered left, right and against the support and then impacted. The operator can optionally be supported by the proven testXpert® testing software. Data output may be accomplished via a simple ASCII or ODBC report.
