Embodiment 1

[0045] like figure 1As shown, an embodiment of the method for simulating invisible links of a CNC machine tool includes the steps of:

[0046] S100. Generate a first training set according to the test data of the invisible link, and obtain a prediction model corresponding to the invisible link through training based on the first training set.

[0047] The invisible links may be directly purchased black-box components whose internal structure and specific working principles are unknown, such as gearboxes, packaged transformers, etc., and due to the influence of actual manufacturing errors, operating environment, and service life, the unobservable links are not known. The output of the appreciable link will not exactly match the theoretical design value. When the invisible link exists independently, its output data can be collected, such as the output torque and output speed of the gearbox, which can be obtained by installing test equipment in the laboratory, but when the invis...

Description

technical field [0001] The invention relates to the technical field of numerical control machining, in particular to a method, a device, a terminal and a storage medium for simulating invisible links of a numerically controlled machine tool. Background technique [0002] The digital twin model is used to perform near real-time calculations on the data collected on the production site to realize simulation, so as to obtain an accurate cognition of the working conditions of the production site and make decisions in line with events. However, for CNC machine tools, there are some links where the output data cannot be collected in real time and the internal structure is not clear, so accurate output data cannot be inferred. This link that cannot obtain accurate real output data is called invisible link The invisible link can be a single component or a combination of multiple components. The invisible link can be regarded as a black box, and its internal structure needs to be dis...
