Abstract: The invention provides a measurement method and system of undeformed chip thickness in micro-milling. This method includes the steps of: S1: acquiring a surface topography picture of the bottom of a flute after micro-milling; S2: extracting a tool mark at the central line of the flute from the surface topography picture; S3: calculating a spacing distance between adjacent tool marks and calculating the difference of equivalent cutting radius between adjacent cutter teeth based on the spacing distance between adjacent tool marks; and S4: reconstructing the instant undeformed chip thickness in micro-milling based on the difference of equivalent cutting radius between adjacent cutter teeth.

Abstract: The present disclosure relates to a communication system based on a neural network model, and a configuration method therefor. The communication system includes at least one master node and multiple child nodes that are in communication connection with the master node, and a child node neural network model is configured in each of the multiple child nodes. The configuration method for the communication system includes: obtaining feature information of the multiple child nodes; and dynamically configuring the child node neural network models on the basis of the obtained feature information.
