In the materials used in the construction, different properties are manifested when subjected to external stresses. To determine the mechanical properties of the materials, different mechanical testing machines are used, with the Charpy test we can establish exclusively the impact resistance, tenacity, in many cases when not taking into account these factors, great damage has been produced. The present project aims to show the different stages of the manufacturing process of the didactic impact test machine, as well as: know the standard and its adaptation to our design, show the manufacturing processes involved during the manufacture of the machine, illustrate the redesign or modification of the proposed design due to technical issues at the time of manufacture. The Charpy pendulum to be designed will serve as a testing machine for teaching purposes within the learning work of students ...
