CNC Machining Design Guidelines
Designing with manufacturability in mind is key to achieving stable quality and optimal machining efficiency.
Features
Description
Part Size
Standard 3-axis mills accommodate 500×400×300mm to 2000×1000×800mm workpieces depending on machine class. Verify specific capacity with manufacturer before finalizing design dimensions.
Tolerance
Standard CNC: ±0.05–0.1mm (metal), ±0.1–0.2mm (plastic). Precision machining: ±0.02–0.05mm with tighter control. Specify tolerances realistically to balance cost and manufacturability.
Features & Geometries
Use fillets ≥0.5mm (preferably ≥1mm) on internal corners. Design ribs at 50–75% adjacent wall thickness. Avoid sharp angles and deep pockets for tool access and reduced stress.
Wall Thickness
Minimum walls: aluminum ≥1.5mm, steel ≥2.0mm, plastics ≥2.0mm. Uniform thickness prevents vibration, deformation, and warping, ensuring dimensional stability and consistent surface finish.
Holes & Threads
Holes ≥1.0mm (metal) or ≥1.5mm (plastic), depth ≤10×diameter. Standard threads M3–M16, depth 1.5–2×nominal diameter. Avoid fine pitches or excessive depth for precision.
Undercuts
Limit undercuts to essential features. T-slots: 3–40mm wide; dovetails: 45–75° angles. Complex undercuts require specialized tooling or EDM, significantly increasing cost and lead time.

CNC Machining FAQs
CNC (Computer Numerical Control) machining is a subtractive manufacturing process that uses automated, computer-controlled cutting tools to produce metal or plastic parts with high accuracy. At Livepoint, we provide 3-axis milling, CNC turning, grinding, and EDM to support both rapid prototypes and tight-tolerance custom components.
CNC machining offers high precision, repeatability, fast material removal, and the ability to create complex geometries without expensive tooling—making it ideal for both prototyping and production.
However, the process can generate material waste, may require skilled operators for complex programming, and is less cost-effective for very small runs compared with 3D printing or low-tooling processes.
China CNC machining manufacturers provide a unique combination of competitive labor costs, fast production cycles, advanced equipment, and flexible capacity. This allows overseas customers to achieve better pricing, shorter lead times, and reliable quality compared with many local manufacturing markets.
Yes. Livepoint provides detailed DFM feedback covering tolerances, manufacturability, wall thickness, tool access, and potential risks to ensure your parts can be produced accurately and cost-effectively.
CNC machining pricing depends on material type, part complexity, tolerance level, surface finishing, and order volume. Upload your STEP/STP/IGS/STL files, and we will provide a competitive quote—usually within 24 hours.
Livepoint supports 3-axis milling, turning, grinding, and EDM with a machining stroke of 800–3200 mm and tolerances as tight as 0.005–0.01 mm. We work with aluminum, steel, stainless steel, copper alloys, titanium, and a variety of engineering plastics.
No. Livepoint offers zero MOQ, from single prototypes to large-scale production runs.
