Design for Manufacturability (DFM) Rules for CNC Milling
Adhering to these core CNC milling guidelines reduces cycle time, eliminates costly tool vibration, prevents part deformation, and ensures guaranteed sub-micron tolerances.
1. Minimum Wall Thickness
Recommended minimum wall thickness for metals is 0.8 mm (down to 0.5 mm in local pockets) and for plastics is 1.5 mm to prevent tool chatter, harmonic vibration, and deflection.
Eliminates Deflection2. Internal Corner Radii
Specify an internal radius of R ≥ 1/3 of pocket depth. Sharp 90° vertical internal corners cannot be machined by round end mills and require slow, expensive EDM wire burning.
Reduces Cost 30%3. Pocket Depth Ratios
Keep deep cavities within ≤ 4× the milling tool diameter. Cavities deeper than 4× require long tool reach, which slows chip evacuation and increases surface roughness.
Prevents Tool Breakage4. Hole Depth & Tapping
Standard drill depths should be ≤ 5× diameter. For tapped holes, an effective thread depth of 1.5× to 2× diameter provides 100% of fastener pull-out strength.
Full Fastener Holding5. Standard Tool Sizes
Design internal fillets and radius sizes to match standard metric end-mill sizes (e.g. 1mm, 2mm, 3mm, 6mm, 10mm). Custom tool grinding adds unnecessary setup lead time.
Off-the-Shelf Speed6. Edge Chamfers vs Radii
Specify 45° chamfers rather than rounded edge radii on top part perimeters. Chamfers can be cut with a standard spot drill or chamfer mill in a single pass.
Cuts Cycle TimeFrequently Asked Questions about CNC Milling
What machine axes do you operate for milling?
We operate 3-axis high-speed machining centers, 4-axis rotary indexers, and continuous 5-axis simultaneous CNC machines (Makino, Haas, Röders) with spindle speeds up to 42,000 RPM.
Can you hold ±0.005mm tolerances on production batches?
Yes. In our temperature-controlled machining facilities (20°C ±0.5°C), we routinely hold sub-micron tolerances down to ±0.005mm verified on Zeiss coordinate measuring machines.
What CAD formats provide the fastest and most accurate quote?
We recommend STEP (.stp, .step) or Parasolid (.x_t) paired with a 2D PDF drawing detailing critical tolerances, tapped threads, and surface roughness requirements.
What is your Minimum Order Quantity (MOQ)?
We have no MOQ requirement. We manufacture single-piece rapid functional prototypes (1 pc) up to high-volume pilot production runs (10,000+ pcs).
