Ultrasound used to guarantee process control in the manufacture of components. A case study
In industry, there are several processes of production, and often, engineers put attention only on volume of production and few times in process control, then emerges the classic problem between the department...

Thermo-mechanical fatigue approach to predict tooling life in high temperature metal forming processes
In high temperature metal forming processes, strong mechanical and thermal cyclic loads coexist in the formed material and in the tooling. Such a phenomenon has a negative influence in the tool life cycle. The...

Improving the Motion of Walking Machines by Autonomous Kinematic Calibration
Legged machines designed to walk on flat or irregular terrain do not need to possess great foot positioning accuracy in order to perform stable motion. However, the propulsion of the body—which normally follow...
