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.
