  • A prediction-correction scheme for microchannel milling

    Abstract In this paper a prediction-correction scheme is proposed to online measure and regulate the milling depth of microchannel using an indicator of laser triggered plasma. Firstly a prediction model with respect to the laser fluence and feedrate is established with several calibration tests using the least square fitting method.
