Design of a feedback algorithm to control axial actuators movement in tube hydroforming process

Tube Hydroforming (THF) process is nowadays gaining more and more importance especially in automotive industry. Several companies developed dedicated equipments for the THF series production and THF is becoming a reference technology due to its advantages. This paper deals with the development and testing of a feedback algorithm to control axial actuators movement in a THF equipment. The algorithm and the whole THF device were designed and manufactured by the Technologies and Manufacturing Systems Research Group of University of Brescia and Bergamo with the cooperation of several companies, and it is currently working in the University of Brescia lab.
