[0019] In order to make the purpose, technical solution and advantages of the present invention clearer, the present invention will be further elaborated below in conjunction with the accompanying drawings.
[0020] In this example, see figure 1 As shown, the present invention proposes a tool life prediction method, comprising steps:
[0021] S1, collect the spindle current signal of the processing machine through the current sensor, repeatedly sample the current signal in units of time and label the collected current signal; obtain real-time current signal and historical current signal;
[0022] S2, extracting the eigenvalues of the current signal through feature learning;
[0023] S3. Cleaning the current signal data according to the characteristic value of the current signal, and normalizing the cleaned signal to obtain real-time input data and historical input data respectively;
[0024] S4, analyze the relationship between the current signal and tool life through mach...
