File, offcut and measure in laser cutting

Cutting starts with a clear file, not machine speed. If offcut, measure and piece marks are not closed before the cutting order, the shop cuts the last conversation — not the right drawing.

A laser-cutting request often starts with “can you cut this part?” The question is incomplete. Without the file, the material, the offcut plan and the delivery mark, there is no cutting plan. At NFS Çelik & Yapı the laser line serves our own fabrication and subcontract work on the same bed. A DXF or DWG goes straight into preparation; a dimensioned sheet or a hand list is also accepted. The bed is not loaded until the dimensions are confirmed.

If the file is unclear, the offcut is unclear

Plate nesting is built with offcut in mind. Place the same part without corner allowance and cutting order and the waste grows; omit a small hole diameter and the part is cut but unusable. Thickness and table size are not published as figures here: they are confirmed in writing for that request once the file arrives. The plan is then built around the actual parts, not around stock. Subcontract work follows the same rule; parts outside our own fabrication run on the same line, under the same file discipline.

The job does not end when the cut ends

After the cut, burr, edge and measure are checked; nothing ships unmarked. The mark ties to the erection order or the client’s piece list. The measure record goes into the delivery pack. Skip that step and the site asks “which part goes to which grid?” — and looks for the answer in a pile off the truck. A useful cutting handover is the part that matches the drawing, plus the check record, plus a marked list.

The cutting order is written after the file is closed. Keeping that order cuts both offcut and site confusion.
