Perpendicularity

On the shop floor, Perpendicularity can be understood as: Deviation from perpendicularity to a datum. Good control here reduces both scrap and unnecessary overprocessing. Treating it as controlled process data reduces shift-to-shift variation. Coordinate-chain integrity is the key control point when setups are repeated across fixtures.

Production Relevance

This item performs best when programming, setup, and quality teams review it together. Cross-functional control is what keeps results repeatable after handoffs.

Practical Controls

• Control thermal and clamping influence during capability studies.
• Define acceptance examples for operator and inspector consistency.
• Align datum interpretation across programming, setup, and inspection.

Frequent Issues

Ignoring gauge variation can hide real process drift. Symbol misinterpretation can pass local checks but fail assembly-level requirements.

Release Checks

• Run periodic gauge capability checks on critical characteristics.
• Trend capability metrics together with roughness outcomes.
• Inspect edge condition and burr state on tight features.
