The present invention provides a method and
system for collecting and analyzing 3D printing tooling fixture data based on
big data, which relates to the fields of 3D printing and intelligent
manufacturing technology. It includes obtaining fixture historical design schemes,
processing parameters, and sensor data, and performing
feature extraction and data cleaning to form structured data. Then, based on the BERT-CNN model, the
design intent is parsed, and a fixture applicability classification
database is constructed in combination with a classification model. Subsequently, a lightweight fixture structure is generated using a
generative adversarial network and
topology optimization, and its topology structure is optimized through an optimization model. Next,
simulation analysis is carried out to evaluate the force, deformation, and thermal stress, and the error is optimized based on the
simulation parameters to obtain the optimized fixture
design data. Finally, the fixture is manufactured and the force data is collected in real time, and the
processing process parameters are optimized through dynamic analysis. The present invention optimizes the fixture design and manufacturing through data driving, improving the design efficiency and fixture performance.
