Role of CAD-CAM Integration in the Additive Manufacturing Process Chain

CAD-CAM integration connects the digital product design with the manufacturing process.

Process chain

1. CAD modeling: The component is created using solid or surface modeling software.
2. File export: The model is exported into a manufacturing-compatible format such as STL or another modern 3D-printing interface.
3. Model checking: The geometry is inspected and repaired for gaps, inverted normals, non-manifold edges and other mesh problems.
4. Part orientation: The model is oriented to balance surface quality, build time, strength and support requirements.
5. Slicing: The model is divided into thin cross-sectional layers.
6. Tool-path generation: CAM software determines the path of the print head, laser, nozzle or other energy source.
7. Machine instructions: The toolpath is converted into machine-specific instructions.
8. Manufacturing: The 3D printer builds the component layer by layer.
9. Post-processing and inspection: The printed part is cleaned, finished and inspected against the design requirements.

Importance

CAD-CAM integration reduces manual data conversion, improves dimensional consistency, speeds up design-to-production, enables rapid prototyping and makes it possible to manufacture complex geometries directly from digital models.
