Precision 6061 Aluminum Cantilevered Motor Housing with Warpage Control

We successfully manufactured a precision 6061 aluminum cantilevered cylindrical motor housing for a compact servo motor application. This asymmetric single-side cantilever design presented significant machining challenges — including unilateral warpage after cantilever machining, internal corner clean-out in cantilevered cutouts, and multi-hole mounting pattern perpendicularity control. Through custom fixturing, optimized toolpath strategies, and precision machining sequences, we achieved dimensionally stable components with all critical features held to specification.

Project Overview

Key Technical Highlights

• Asymmetric Warpage Prevention: Implemented stress-relief machining sequences and custom low-stress fixturing to control unilateral distortion after cantilever material removal, maintaining critical housing geometry within tolerance.
• Process Innovation:
  • Balanced Material Removal Strategy: Staged roughing and finishing passes with controlled depth-of-cut minimize stress-induced deformation in asymmetric cantilever sections.
  • Internal Corner Clean-Out: Specialized toolpath strategies and custom tooling achieve clean internal corners in cantilevered cutout features — eliminating stress risers and ensuring proper component fit.
  • Perpendicularity Control: Single-setup machining with precision fixturing ensures all mounting holes maintain ≤0.01mm perpendicularity to the cylindrical housing axis.
• Quality Assurance:
  • Single-setup machining eliminates re-fixturing errors and ensures geometric consistency across all features.
  • CMM verification confirms dimensional stability and perpendicularity requirements.

Quality Verification

Each component underwent comprehensive inspection using CMM measurement for dimensional accuracy (±0.02mm on critical features), perpendicularity verification (≤0.01mm on mounting hole patterns), and visual inspection for internal corner quality and surface finish.
