Rules Using This Reference

Rule Pack Severity Title
ASM-001 E_ASSEMBLY minor Reduce part count by combining parts where no “minimum part criteria” applies
ASM-002 E_ASSEMBLY minor Reduce fasteners
ASM-003 E_ASSEMBLY minor Standardize components
ASM-004 E_ASSEMBLY minor Minimize reorientation/flips in assembly sequence
ASM-005 E_ASSEMBLY minor Add poka-yoke features to prevent wrong orientation
ASM-006 E_ASSEMBLY minor Easy handling: avoid tiny/flexible/slippery parts without handling features
ASM-007 E_ASSEMBLY minor Clear symmetry/asymmetry for orientation (avoid ambiguous “looks same”)
ASM-008 E_ASSEMBLY critical Minimize secondary operations & inspection steps (flag deburr-only parts, hand rework)
SPEC-025 A_DRAWING major Assembly drawing includes BOM + callouts for joining method
SRV-001 E_ASSEMBLY minor Ensure tool access to fasteners (wrench clearance) in final assembly
SRV-002 E_ASSEMBLY minor Minimize unique tool types (hex sizes, torx types)
