Educational compression testing machine for teleoperated teaching of the metals flow curves

Today in the world, there are numerous educational experiments teleoperetad to support the teaching of engineering, but the number of this remote experiments in the area of metal forming is not enough. This article will show a new remote experiment called Educational Compression Testing Machine teleoperated via Internet. This experiment will create the possibility for the students to do a real compression test and to collect force applied in the specimen and size data during the experimentation process. These data will be useful for the construction of flow curve of metals aiming the calculation for projects of formed parts. The remote experiment is divided in two basic parts: the website and the Educational Compression Testing Machine. For data acquisition, control and data processing, as well as the interface between the user and the machine was used the Raspberry Pi that is a small size and low cost microcomputer. The reduced structure for the experiment and the low cost were defined as priority for this work, aiming to fit the necessity of undeveloped countries.
