Aluminum CNC Machining Design Guidelines
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.
