Abstract : The load spectrum of machining center (MC) is the data basis for fatigue life prediction. A novel compiling method of dynamic cutting
load spectrum of MC spindle is proposed, and then applied to the fatigue life prediction. Typical process parameters were determined
based on the data collected in the user field by establishing the characteristic load distribution, and dynamic cutting load was measured
using the load test platform. Mean-frequency and amplitude-frequency matrices of the load were obtained by the rainflow counting
method, and mixture Weibull distribution (MWD) was used to establi
