First Article

By Kribashan Munsamy, Mr

A practical shop-floor note on first-article checks for teams that want cleaner laser starts on Monday morning.

The first sample off the bed sets the tone for the whole batch. If dimensions, edge condition or part ID are not checked early, scrap grows fast. First Article is our note for plants using fibre laser cutting on repeat production work.

First Article starts with the first parts off the bed, not with a long report later in the shift. On fibre laser work in Gauteng, KZN and the Western Cape, teams usually check overall size, pierce marks, edge colour and part marking before the nest carries on.

Monday-morning first-piece checks

• Sheet grade and thickness confirmed
• First cut part measured and photographed
• Laser model and program name recorded
• Part number matches traveller and nest

First Article covers what the operator, setter and supervisor should verify before repeat production builds pace. That keeps cut quality, traceability and material use aligned from the first nest.

How First Article works in day-to-day production

First Article is about checking the first cut parts before the nest runs at full pace. A proper first-article check on Monday morning can catch setup drift, material issues and edge problems before a whole batch is affected.

Start with the material, thickness and expected finish. Mild steel, stainless and aluminium react differently to nozzle condition, assist gas setting and pierce timing, especially after a weekend stop. In Johannesburg dry dust can affect consumables, while Durban moisture can show up quickly on stored sheet.

Do not skip the first sample photo and the first measurement record. A simple card near the laser helps the shift note actual nozzle size, gas type, focus position and any edge issue seen on the first parts. That record is often what stops the same scrap pattern repeating on the next restart.

Plant conditions that affect first-offs

Allow for power interruptions, sheet handling delays and mixed stock in the rack before the shift starts. Many South African plants are not cutting one material all day, so the first-article routine needs to catch wrong thickness, protective film left on, and old program selection. If the line is in live production, separate urgent cut issues from routine process review.

Coastal air can influence sheet condition and cleaning frequency around optics and covers. Inland dust often shows up in nozzle wear, sensor contamination and assist gas housekeeping. After any stop-start event, the first-off part deserves another dimensional and edge check before the nest continues.
