Material Properties & Machining Notes
The points below are for reference only. Final material selection and tolerance planning depend on grade, stock condition, part geometry, and working environment. For geometry review, see our plastic CNC machining DFM guide.
Key Properties
CNC Machining Notes
- Tooling and cutting strategy should control heat and burrs.
- Thin features and deep holes need machining feasibility review.
- Annealing or stress control may be considered for tight tolerance parts.
- Surface finish and edge condition should be defined on the drawing.
