CADSynth: A Dataset for Machining Feature Recognition in B-rep Models

This dataset contains 100,000 synthetic CAD models with machining feature labels, supporting data-driven deep learning methods for machining feature recognition.

The CADSynth dataset provides three types of data files for each CAD model. These include a STEP file, which records the three-dimensional shape of the CAD model (compliant with ISO 10303-21 and GB/T 16656 standards), a JSON file that records the machining feature labels corresponding to each topological face (compliant with ECMA-404 and ISO/IEC 21778:2017 standards), and a B-rep data graph representation file (with a .bin extension), which can be used for deep learning training (formatted for the Deep Graph Library, an open-source graph neural network framework).
