| Incomplete cut-through | Glue-line variation, core overlap, repair or density shift | Focus, energy, pass count, support or contamination | Section failed positions and compare the machine record | Re-screen construction and run the recorded cutting trial | Any material/process adjustment or repeated failure |
|---|
| Wide or inconsistent kerf | Thickness or density variation across the sheet | Focus, optics, motion or compensation drift | Measure top/bottom kerf by sheet position | Restore process condition or revise the agreed allowance | Kerf outside the agreed range |
|---|
| Dark edge beyond sample | Denser construction, glue-line or moisture change | Excess energy, poor focus or slow motion | Compare edge to the cleaned agreed sample | Trial material and settings together | Edge appearance differs from the agreed sample |
|---|
| Excess visible smoke | Coating, adhesive or contamination differs | Extraction, filtration, air assist or settings are outside the recorded machine settings | Verify material identity and extraction state | Stop, correct controls and repeat the recorded cutting trial | Visible smoke target is not met |
|---|
| Surface residue or rub-off | Face treatment or chemistry changed | Extraction, masking, bed or cleaning option is ineffective | Perform the agreed wipe and surface inspection | Correct process/cleaning and approve a new reference | Residue exceeds the agreed surface limit |
|---|
| Glue spots / local flare | Local glue pocket, repair or overlap | Focus or airflow intensifies a local event | Map flare to cut path and inspect the cross-section | Change material construction or controlled process window | Any unexpected flare on a critical feature |
|---|
| Back marking | Reverse face or construction is more heat-sensitive | Bed contamination, reflection or poor support | Inspect reverse face and bed contact pattern | Clean/change support and repeat on the exact panel | Back mark exceeds agreed reference |
|---|
| Poor engraving contrast | Face colour, grain or finish varies | Engraving step, focus or cleaning differs | Compare three engraving steps after cleaning | Select face option or revise agreed engraving settings | Contrast/cleanliness differs from the agreed reference |
|---|
| Small holes fail to release | Void, repair or glue-line crosses the feature | Focus, kerf or energy is unsuitable for diameter | Inspect three hole sizes at multiple sheet positions | Increase feature, change construction or re-trial process | Any released diameter fails gauge/cleanout |
|---|
| Narrow bridges break | Core support or ply construction is insufficient | Nesting, heat input or handling damages the bridge | Compare break location with veneer/core and handling stage | Increase bridge, select stiffer option or change nesting | Bridge does not survive cutting and handling |
|---|
| Tab-slot fit drifts | Actual thickness distribution or batch construction changed | Kerf compensation or focus drifted | Measure thickness, kerf and assembled joint | Set affected panels aside and restore agreed material/process/drawing | Fit class departs from agreed gauge |
|---|
| Part bows or pack loses flatness | Conditioning, moisture or residual stress differs | Asymmetric cutting, unsupported handling or packing | Measure before/after cutting and inspect pack support | Condition the panels, revise the cutting layout or supports, and check the packing again | Part or kit exceeds the agreed flatness limit |
