7. Machining Instructions
- Material Selection – Confirm alloy or polymer; determine if heat treatment or surface coating is required.
- Tooling – Select carbide end mills for 5‑axis cutting; use diamond tools for polymer work‐pieces.
- Cutting Strategy –
- Roughing: Low feed, high spindle speed; maintain spindle cooling.
- Finishing: High feed, lower spindle speed; employ 5‑axis tool paths for complex surfaces.
- Coolant – Use ISO‑approved coolant for metal parts; for polymers, employ air‑cooling or cryogenic methods to avoid deformation.
- Inspection – Interim CMM checks after roughing and finishing passes.
- Surface Finish – Optional electropolishing or anodizing; polymer parts may receive UV‑curable coatings.
