Engineering and DFM Guidance for Motion-Control Parts

We collaborate early to stabilize performance and cost while protecting critical function.

Datum Strategy and Stack-Up

  • Define functional datums tied to the assembly path (e.g., bearing-seat axis to mounting face)
  • Minimize datum transfers by grouping related features into single setups

Tolerance Allocation

  • Reserve tight tolerances for functional surfaces (bearing bores, rail lands, dowel interfaces)
  • Apply GD&T (position, runout, parallelism, perpendicularity, flatness) to control function, not non-critical profiles

Fits and Finishes

  • Bearing seats: specify class of fit and roundness/cylindricity; we typically grind or finish-bore to final size
  • Sliding ways: call out flatness/parallelism and Ra; confirm orientation of lay
  • Sealing surfaces: define flatness and surface finish; avoid unnecessary surface treatments that affect seal friction

Feature Design

  • Add thread reliefs and undercuts for full-thread engagement on hard alloys
  • Use generous corner radii (≥ R0.5 where function allows); minimum internal corner radius R0.3 mm
  • For thin walls (≥ 0.5 mm), add ribs or machining allowances for stress relief

Materials and Treatments

  • 17-4 PH: specify condition (e.g., H1025) and dimensional strategy across heat treat and finish-grind stages
  • Duplex/316L: consider passivation and galling mitigation for threads/fits
  • Titanium/Nickel alloys: plan for lower MRR, stable fixturing, and potential post-machining stress relief

Cleanliness, Burr Control and Repeatability

  • Specify critical edges to break vs. protect; define deburr/cleaning level for cleanroom or vacuum use
  • Approve a stable process route via FAI; document special processes and gage strategy for repeat production
