| Guideline | Description |
| Wall Thickness | Maintain uniform wall thickness to prevent distortion and ensure even machining. |
| Fillets and Radii | Add fillets and radii to sharp corners for stress reduction and improved aesthetics. |
| Tolerances | Specify appropriate tolerances based on part function and machining capabilities. |
| Material Selection | Choose suitable aluminum grade considering strength, corrosion resistance, and machinability. |
| Undercuts | Minimize undercuts to simplify machining and prevent complex tooling requirements. |
| Tool Access | Ensure proper tool access for efficient machining, accounting for tool lengths and angles. |
| Avoid Sharp Transitions | Smoothly transition between different features to avoid stress concentration and improve aesthetics. |
| Surface Finishes | Indicate desired surface finish (e.g., smooth, matte) for both functional and aesthetic purposes. |
| Internal Cavities | Incorporate proper draft angles and radii for easy removal of machined parts from molds. |
| Threads and Holes | Follow thread and hole guidelines for optimal thread engagement and accurate hole dimensions. |
| Prototyping | Create prototypes to test design before full-scale production, allowing adjustments if needed. |
| Design for Manufacturability | Consider manufacturability to avoid complex geometries, reducing production challenges. |
