CNC Machining Design Guidelines

 Feature Description
Internal corner fillets Design internal corner fillets to be 0.020"-0.050" greaterthan a standard drill size for the radii. Follow a drilldiameter to depth ratio of 1:6 (1:4 recommended) as aguideline for internal corner radii.
Floor fillets Design floor fillets smaller than corner fillets to allow thesame tool to clear material from the interior.
Undercuts Always design undercuts to standard sizes and awayfrom corners so they are accessible by the cutting tool.
Tapped/threaded hole depth Provide tool clearance slightly beyond the tapped holedepth to ensure complete threads.
Complexity Keep the number of small cuts to a minimum to reducethe CNC machining service cost; only design in thenecessary features to balance function with aesthetic.

Precision CNC Machining FAQs

  • Q1: What is CNC machining and how does it work?

    CNC machining is a subtractive manufacturing process where computer-controlled machines remove material from solid blocks to create precise parts. The process uses multi-axis movement—typically 3-axis, 4-axis, or 5-axis—to achieve tight tolerances and complex geometries. CNC machining is widely used for both prototyping and production.

  • Q2: What materials can be used for CNC machining?

    CNC machining supports a wide range of materials, including aluminum alloys, stainless steel, carbon steel, brass, copper, titanium, and engineering plastics such as ABS, POM, Nylon, and PEEK. Material selection depends on strength, corrosion resistance, weight, and cost requirements.

  • Q3: What tolerances can CNC machining achieve?

    Standard CNC machining tolerances typically range from ±0.05 mm to ±0.1 mm. For high-precision parts, tolerances as tight as ±0.005 mm can be achieved with optimized processes and inspection. GD&T features such as concentricity, flatness, and position are also supported.

  • Q4: What is the difference between 3-axis, 4-axis, and 5-axis CNC machining?

    3-axis machining moves the tool along X, Y, and Z axes and is suitable for simple geometries.
    4-axis machining adds rotational movement for improved access.
    5-axis CNC machining allows simultaneous multi-directional cutting, reducing setups and improving accuracy for complex parts.

  • Q5: What surface finishes are available for CNC machined parts?

    Common surface finishes include as-machined, polishing, bead blasting, anodizing, powder coating, electroplating, black oxide, and brushing. Surface finishing improves appearance, corrosion resistance, and functional performance.

     

  • Q6: How long does CNC machining take?

    Lead times depend on part complexity, material, and order quantity.

      √Prototypes: 3–7 days
      √Low-volume production: 1–3 weeks
      √Larger batches: project-based scheduling

    Fast-track options are available for urgent projects.

  • Q7: Is CNC machining suitable for low-volume production?

    Yes. CNC machining is ideal for low to medium volumes due to minimal tooling requirements and flexible setup. It is commonly used for prototypes, custom parts, and short production runs.

     

  • Q8: What file formats do you accept for CNC machining?

    We accept standard CAD formats including STEP / STP, IGES, SolidWorks, and PDF drawings. Clear drawings with tolerance and surface finish requirements help ensure accurate manufacturing.

     

  • Q9: How do you ensure quality in CNC machining?

    Our quality assurance system includes incoming material inspection, in-process quality control, first article inspection (FAI), full dimensional inspection using CMM, surface inspection, and final quality verification with complete reports.

     

  • Q10: Can CNC machining be combined with other manufacturing processes?

    Yes. CNC machining is often combined with casting, forging, 3D printing, surface finishing, and assembly to optimize cost and performance. NAITE TECH provides one-stop manufacturing solutions.
