Machining Instructions – Best Practices for Aluminum Billet Inner Housing
- Tool Selection
- Use high‑speed carbide end mills with TiAlN coating for reduced wear.
- For fine features (< 0.5 mm), select micro‑ball‑nose tools (Ø 0.2–0.4 mm).
- Cutting Parameters (General Guideline)
- Spindle Speed (n): 12 000 – 18 000 rpm.
- Feed per Tooth (fz): 0.02 – 0.04 mm/tooth.
- Depth of Cut (ap): 2 – 6 mm for roughing, ≤ 0.5 mm for finishing.
- Coolant Strategy
- Apply high‑pressure flood coolant directly to the cutting zone.
- Maintain coolant temperature at 15 °C to avoid thermal distortion.
- Tool Path Planning
- Adopt adaptive clearing for roughing to maintain constant chip load.
- Use trochoidal milling for deep pockets to reduce tool deflection.
- Workholding
- Secure the billet on a vacuum table for flat surfaces; employ modular rotary fixtures for internal cavities.
- Verify datum alignment with a touch probe before machining.
- Inspection Points
- Insert probing cycles after each major feature (e.g., housing bore, mounting flange).
- Record deviations and feed them back to the CNC Milling Center Aluminum controller for on‑the‑fly compensation.
- Post‑Processing
- Deburr using a vibratory tumbler or manual hand‑filing for critical edges.
- Perform anodizing or surface hardening if required for corrosion resistance.
