Field: Control (Instruments)
Classification: CPC G | IPC G

Claim 2:
3. The prediction method for tool remaining life of a numerical control machine tool based on a hybrid neural model according to claim 1, wherein the process of acquiring the second feature vector representing the tool life comprises the following steps:
S31: establishing an I*M vector table according to an index after hash coding the PLC working condition signal data, the vector table being expressed as: Vx={xivi},
I being the index number, M being the embedding dimension, xi being an input vector, vi being a mapping vector, and Vx being a vector set; and
S32: acquiring the second feature vector representing the tool life by the acquired vector table Vx through the action of a Bi-Interaction layer.
