Embodiment Construction
[0045] In order to make the objects and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the examples. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.
[0046] In order to prove the accuracy of the diagnostic method of this embodiment, a verification test was carried out in a numerical control machining center of a wood factory. Wood-plastic composite (WPC) is milled with a shank milling cutter with a diameter of 18mm. According to the experimental cutting parameters in Table 2, the power analyzer WT500 is used to collect the machine tool spindle power P t , to create a sample set.
[0047] Such as figure 1 As shown, a kind of woodworking tool wear state diagnosis method based on machine tool spindle power and genetic BP neural network of the present invention comprises the following steps:
