What to Include in a Laser Cutting Drawing
A cut file gives the outline. The drawing has to say what the part is made from, how many are needed, which dimensions matter and what happens after cutting.
A laser cutting drawing is usually two documents doing two jobs. The cut file tells the machine where to cut. The drawing tells the people reviewing the job what the part is meant to be. The machine never needs the second one. The review does.
Send a file and a drawing
DXF or DWG carries the geometry. A PDF of the drawing carries the notes, dimensions and revision. A STEP file helps when the part is not purely flat. KorFab reviews DXF, DWG, STEP, PDF and image files, and vector files produce the fastest quote because nothing has to be traced back into geometry.
One file per part, named the same way as the part, reviews faster than a single sheet holding twelve details. If several parts share a revision, say so once in the request.
What the drawing should state
- Material and thickness. Capacity on the 6 kW fiber laser is confirmed per material rather than taken from one blanket maximum, so the material callout has to be specific.
- Quantity, and whether that quantity is a single release or the first of several.
- Outline, hole, slot and cutout geometry, with the dimensions that must be held called out rather than left to the scale of the print.
- Edge requirements on any cut that will be seen, welded or mated to another part.
- Part marking. The laser etches part numbers, orientation marks and bend lines inside the cutting program, so a mark that must appear is a drawing note.
- What happens next: forming, welding, finishing, or nothing at all.
Where a cut file stops
A DXF carries outline geometry and no judgement. It cannot say that a hole is a clearance hole for a particular bolt, that a slot is weld access, or that one edge is visible after assembly. Those live in the notes. When the notes and the geometry disagree, the review stops until someone confirms which is current, which costs a day in a schedule that may not have one.
The part that continues past the laser
If the blank is formed or welded afterwards, the drawing should say so, because the flat pattern has to be the one that produces the finished part. Planning laser cut parts that need forming covers that case, and what helps a fabrication quote move forward covers the request itself rather than the drawing.
The standard worth aiming at
A drawing that carries material, thickness, quantity, critical dimensions, marking and the next operation answers the questions an estimator would otherwise email back. That is the whole test: the review should not have to guess.
