Abstract : The load extrapolation is to obtain load data that may occur during the whole life cycle of product based on the limited measured
load data, especially extreme load. Aiming at the two problems of traditional time domain extrapolation: without considering the
interval time between extreme adjacent values and the high sensitivity of the peak over threshold (POT) model to the extreme
threshold, a time domain load extrapolation method for computerized numerical control (CNC) machine tools based on Gray
relational analysis-peak over threshold model (GRA-POT) is proposed. Firstly, for the first prob
