[0072] like image 3 As shown, a tool life dynamic prediction method of the present invention includes the following steps:
[0073] S1: Determine the features that affect the tool life and collect relevant information data, obtain historical data, and standardize the historical data;
[0074] S2: Perform correlation analysis on historical data, and delete features whose correlation is within the critical range;
[0075] S3: Perform principal component analysis on the features, reduce and simplify the historical data to obtain modeling data;
[0076] S4: Use the gradient boosting regression tree to train the modeling data to establish a tool life prediction model;
[0077] S5: Collect real-time data according to the characteristics of the modeling data, standardize the real-time data and input it into the tool life prediction model, and output the tool life.
[0078] In this embodiment, the life prediction is performed on the tool used for machining the aviation structural ...
