Numerical and experimental investigation of cooling time in laser micro-adjustment of two-bridge actuators

► This paper presents two cooling criteria including the same temperature (ST) and the room temperature (RT) for laser micro-adjustment of two-bridge actuators. ► The effects of the scaled geometry of actuators on cooling time are investigated numerically and experimentally for different processing parameters. ► The numerical and experimental results show that the cooling time can be saved significantly when using ST cooling criterion.
