[0048] Example: Taking the tool system of the high-end turning machining center DL-20MH as the test object, the YT15 tool is used to cut 45# steel, the cutting speed is given as Vc=200m / min, and the tool status during the machining process is the initial wear and mid-term respectively. For wear and serious wear, the 12 sets of current signals in different states are respectively subjected to variable-scale empirical mode decomposition, and the instantaneous frequency of each eigenmode function is obtained through Hilbert transform, which is used as a conditional attribute to construct the initial decision Information table (as shown in Table 1).
