How to Prepare Your CAD Files to Avoid Extra Fees

Programmers at cutting facilities spend hours fixing broken drawing files. Every minute a programmer spends fixing your CAD model is time added to your lead time, often resulting in an engineering preparation fee.

Here is how to set up your drawing pack so it goes straight onto the machine floor:

• Export files in 1:1 scale in millimeters as clean DXF or DWG files.
• Strip out all dimensions, title borders, fabrication notes, and hatch lines from the cut layer. A laser controller sees every single line as a cut command. If you leave a dimension line on the main layer, the laser head will try to burn it into your sheet.
• Place bend lines and etching text on their own separate, clearly labeled CAD layers.
• Check your line geometry for tiny gaps or duplicate overlapping vectors. Double lines cause the machine head to pause and recut the same path, creating burn marks.
• Provide STEP or IGES files whenever you need press brake folding so the operators can check your flange clearances and material bend deductions before firing the laser.

Frequently Asked Questions

What dimensional tolerances can I expect on mild steel plate?

On sheet metal up to 6 mm thick, high-end fiber lasers hold tolerances between plus or minus 0.1 mm and 0.2 mm. On heavier plate over 16 mm, thermal expansion and natural beam divergence create a slight edge taper, expanding tolerances closer to plus or minus 0.3 mm or 0.4 mm.

Why is fiber cutting better than waterjet or plasma for sheet metal?

Plasma cutting creates a wider kerf with noticeable edge taper and dross, especially on thinner gauges. Waterjet provides tight accuracy without heat effects, but it runs much slower and costs significantly more per hour. Fiber laser hits the sweet spot for fast, sharp, cost-effective sheet metal fabrication.
