Optimizing Part Design to Reduce CNC Machining Costs

Design decisions significantly impact machining complexity and cost. Common design pitfalls include:

Simplify Geometry

Avoid deep pockets, sharp corners, or thin walls requiring special tooling. Use fillets instead of right angles to reduce stress concentration.

Tolerance Rationalization

Non-critical features can use ±0.1mm tolerances instead of precision grades, cutting machining time.

Minimize Setups

Design for multi-axis machining in single setups when possible.

Standardize Features

Use uniform hole sizes/threads to minimize tool changes.

Early design consultation typically saves 15-30% in machining costs.
