Design chapter 1
Walls & internal geometry
Wall Thickness
1.5–3.0mm aluminum / 2.0–4.0mm steel
Maintain uniform wall thickness at 1.5–3.0 mm for aluminum parts and 2.0–4.0 mm for steel parts to avoid deformation and machining instability.
Internal Corners
R0.8–R1.5 minimum fillet
Avoid sharp internal corners; use minimum fillet radius ≥ R0.8–R1.5 to match standard end mill tools and reduce tool wear.
