Abstract
A temperature control algorithm has been developed that contains an inner loop to control power and an outer loop to command power based on temperature feedback. The foundation of the control algorithm used in this work is the fact that spindle power leads tool temperature. This fact will be proven through analytical models and experimental data. Commanding spindle power to control temperature is a significant paradigm shift for some members of the friction stir processing (FSP) community.
The anticipated benefits of temperature control during FSP include: decreased variation in properties throughout the length of the weld, increased repeatability, increased tool life and extension of the application of FSP. This paper summarizes previous research, and investigates theory relevant to temperature control in FSP. Subsequently, the current state of temperature control technology and experimental data are presented.
