Process	Best For	Precision & Surface	Cost & Volume	Applications	Key Takeaway
CNC Milling	Prismatic parts, complex 3D shapes	High precision, smooth finish	Low–medium volume, fast turnaround	Engine brackets, housings, molds, prototypes	Flexible, accurate, and ideal for prototypes & production parts
CNC Turning	Cylindrical & rotational parts	Excellent roundness & concentricity	Low–medium volume	Shafts, bushings, threaded rods, rollers	Most efficient for rotational geometries
EDM / Wire-Cut	Sharp corners, deep cavities, hardened steels	Ultra-high precision, no tool marks	Slow, higher cost	Mold cavities, fine slots, intricate dies	Use when milling cannot reach
Metal 3D Printing	Internal channels, lattices, lightweight designs	Moderate precision, post-machining required	Low volume, higher cost	Aerospace brackets, medical implants, conformal cooling inserts	Excellent for complex shapes, best with CNC finishing
Die Casting	Thin-walled, high-volume metal parts	Good dimensional stability, some machining needed	High upfront tooling, low per-part cost	Automotive housings, heat sinks, appliance parts	Best for mass production after design validation
Sheet Metal Fabrication	Thin plate structures, enclosures, brackets	Good accuracy for 2D profiles & bends	Low–high volume, fast	Electronic housings, cabinets, chassis, frames	Cost-effective for lightweight structural parts

Design Feature	Guidelines
Part Size	Max size: 3000 × 1500 × 600 mm (5-axis). Design within machine envelope for optimal efficiency.
Wall Thickness	Metals: ≥ 0.8 mm；Plastics: ≥ 1.5 mm. Thin walls can lead to vibration, warping, or failure.
Internal Radii / Fillets	Radius ≥ 1/3 of cavity depth. Larger radii allow the use of bigger, more stable milling tools.
Cavity Depth	Should not exceed 4× width. Deeper cavities risk tool deflection and poor surface finish.
Holes	Minimum hole Ø: 1 mm. Recommended depth: ≤ 10× diameter. Follow standard drill sizes.
Threads / Tapped Holes	M2–M16 supported. Ideal depth: 2–6× thread diameter. Custom threads available on request.
Text & Logos	Engraved text: Minimum width 0.5 mm, depth 0.1 mm. Laser engraving also available.
Undercuts	T-slot: 3–40 mm wide. Dovetail: Standard angle 45° or 60°. Avoid if not essential.
Feature Orientation	For 3-axis CNC, align features on a single face to reduce repositioning and cost.
