Customized 3 Axis 4 Axis 5 Axis CNC Machining Parts: A Complete Guide
Understanding CNC Machining Axes: Capabilities and Applications
3 Axis CNC Machining
3‑axis CNC machining moves a cutting tool along the X, Y, and Z linear axes. It excels at producing flat surfaces, slots, and simple pockets in a single setup. Typical applications include brackets, panels, and early‑stage prototypes. However, complex angles or intricate undercuts require manual part repositioning, adding time and potential error.
4 Axis CNC Machining
By adding an A‑axis rotation, 4‑axis CNC machines can index cylindrical parts such as shafts, cam lobes, and gear blanks. This capability streamlines production of automotive pulleys, turbine blade preforms, and watch components—no secondary setup needed for machining around a cylindrical surface.
5 Axis CNC Machining
The pinnacle of flexibility, 5 axis CNC machining offers simultaneous B and C‑axis rotation in addition to linear movement. This enables one‑pass machining of aerospace impellers, medical implants, and complex molds with radiused corners. With tolerances as tight as ±0.005 mm and surface finishes down to Ra 0.4 µm, 5‑axis CNC parts eliminate multiple fixtures, cut cycle times by up to 60%, and reduce human error.

How to Design Parts for CNC Machining
Design for Manufacturability (DFM)
- Avoid sharp internal corners: Use radii ≥ 1 mm to match end mill geometry.
- Limit deep, narrow cavities: Shallow pockets reduce tool deflection and chatter.
- Uniform wall thickness: Prevents distortion and overheating during high‑speed cutting.
Material Selection Guide
- Aluminum 6061: Lightweight, easy to machine, ideal for prototypes and consumer products.
- Stainless Steel 316: Excellent corrosion resistance for marine or food‑grade applications.
- Titanium Grade 5 (Ti‑6Al‑4V): High strength‑to‑weight ratio for aerospace and high‑performance automotive parts.
Cost Factors in Custom CNC Machining
Machine Setup Complexity
- 3‑Axis: Simple fixturing and toolpaths; typical rates of $50–$100/hour.
- 5‑Axis: Advanced toolpath generation and simultaneous multi‑face machining; rates of $150–$300/hour.
Material and Volume
- Aluminum parts: $20–$50 per unit in bulk; cost decreases with volume.
- Low‑volume titanium: $200–$500 per part due to material and tooling wear.
Post‑Processing
- Anodizing: $10–$30 per part for color and corrosion resistance.
- Powder coating: $15–$50 per part for durable finishes and branding.
