In this paper, the loading path was optimized in hot metal gas forming (HMGF) process for making AA6063 cylindrical stepped tubes. For purpose, response surface method (RSM) and finite element (FEM) were applied using Design-Expert ABAQUS softwares, respectively. The parameters of internal pressure, pressure rate, axial feeding, punch speed examined based on central-composite design three level...

Grinding robots are widely used in the automotive, mechanical processing, aerospace industries, among others, due to their strong adaptability, high safety and intelligence. The grinding process parameters main factors that affect quality efficiency of robots. However, it is difficult obtain optimal combination only by manual experience. This study proposes an artificial intelligence-based meth...
