The invention belongs to the technical field of
laser precision
machining and intelligent manufacturing, and particularly relates to a
laser machining parameter transfer learning method,
system and equipment and a medium, and the method comprises the following steps: S1, specifying a
machining requirement, and inputting known physical characteristics and an initial
laser parameter range of a to-be-machined material; s2, establishing a basic model
library containing a multi-
physics field
coupling model, and constructing a laser parameter-electronic dynamics-
processing result mapping
database based on historical experimental data and
model simulation results; and S3, based on the
physical model library and the mapping
database, training a
machine learning or
deep learning model as a prediction model. According to the method, a multi-
physics field
coupling model and a data driving model can be fused, the
interpretability of the model is ensured by utilizing a physical mechanism, and the prediction precision is improved through
mass data training; and the three-stage feedback mechanism realizes real-time adaptive adjustment in the
machining process, so that the key index deviation of the machining result can be within an effective control range.
