Acceptance checklist

CNC Machine Acceptance Checklist

Verify machine-tool evidence before purchase, relocation, commissioning, or final sign-off.

Direct answer: machine acceptance should verify geometry, positioning, thermal stability, safety, documentation, and trial-part evidence before sign-off.

CNC Machine Acceptance Checklist

Procurement and commissioning checklist for machine geometry, positioning, thermal behavior, safety, documentation, and trial cuts.

Acceptance area	Evidence to request	Pass / hold condition	Handoff
Geometry	Leveling report, squareness, straightness, backlash checks	Hold if machine is not leveled or baseline geometry is missing.	ISO 230-1 / GB/T 17421 geometry path.
Positioning	Laser/interferometer axis report with repeatability values	Hold if accuracy limit is not tied to contract or spec.	ISO 230-2 guide and reference table.
Thermal behavior	Warm-up notes, ambient condition, drift observations	Hold if tolerance claims depend on uncontrolled temperature.	ISO 230-3 or builder thermal compensation evidence.
Safety and interlocks	Door, E-stop, spindle, coolant, and chip conveyor checks	Hold if any safety function is bypassed.	Commissioning sign-off.
Documentation	Parameter backup, ladder backup, manuals, options list	Hold if backup or option evidence is missing.	Maintenance and service handoff.
Trial part	Material, program, inspection result, cycle-time observation	Hold if trial evidence does not match the intended production use.	Equipment selection and ROI assumptions.
