Positioning

In production use, Positioning is commonly defined as: Determining the workpiece position on the machine. It determines whether the part is located and supported consistently under load. A clear standard around this topic usually shortens prove-out time. Validate this under real cutting load, because static setup checks can miss deformation effects.

Shop-Floor Effect

Use a system-level review before changing values here. Coordinated checks across process steps usually outperform isolated adjustments.

Best-Practice Steps

• Verify tool and probe access before releasing fixture design.
• Standardize jaw and fixture changeover with controlled reference surfaces.
• Reconfirm datum transfer after each reclamp operation.

Early Indicators

• Local distortion near clamping points
• Frequent manual touch-up after reclamp
• Datum shift between first and later parts

Stability Risks

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

Before-Run Checks

• Clean contact faces and remove chips before clamping.
• Verify clamp sequence and torque consistency across operators.
• Measure critical datums both clamped and unclamped on trials.
