Designing parts for CNC machining requires understanding the capabilities and limitations of the process. These 10 essential design tips will help you create better parts.
1. Avoid Deep Cavities
Limit cavity depth to 4x the tool diameter. Deeper cavities require longer tools prone to deflection and vibration.
2. Use Standard Tool Sizes
Design internal radii to match standard tool diameters. This eliminates custom tooling and reduces machining time.
3. Minimize Setup Changes
Design parts to be machined in as few setups as possible. Each setup change adds cost and introduces alignment errors.
