Blank

For CNC teams, Blank points to this concept: Raw material form before machining. Reliable workholding is the foundation for dimensional repeatability. A clear standard around this topic usually shortens prove-out time. Its best results come from disciplined execution across shifts, machines, and operators.

Best-Practice Steps

• Define locating strategy that constrains required degrees of freedom.
• Set clamping force to prevent slip without deforming compliant areas.
• Verify tool and probe access before releasing fixture design.
• Standardize jaw and fixture changeover with controlled reference surfaces.

Practical Warning Signs

• Frequent manual touch-up after reclamp
• Datum shift between first and later parts
• Feature spring-back after unclamping

Risk Focus

A setup can look stable at rest and still shift once cutting forces rise. Over-clamping introduces elastic error that appears after unclamp.

How Teams Standardize It

Teams usually stabilize this area by verifying datum transfer at every operation handoff.

• Keep setup records and inspection evidence linked to each process revision.
• Re-validate after tooling, fixture, or control-logic changes.
• Use first-article and restart checks as mandatory release gates.
