How to send a drawing for CNC plasma cutting.
A clean file means a faster quote and parts that fit the first time. You don't need CAD to order, but if you have it, here's what helps.
Which file to send
- DXF or DWG is best. It goes almost straight to the cutting table.
- PDF drawing with dimensions works. We'll draw the cut file from it.
- A sketch or a sample part works too. Measure carefully or bring the part in, and we'll trace and draw it.
- A logo or artwork for a sign: send the highest-quality version you have. Vector files (SVG, AI, EPS, PDF) are better than a photo or a small JPG.
Turning a drawing, sketch or logo into a cut file is a one-time $50 setup per design, and it's waived on repeat orders.
Setting up a DXF
- Draw at full size (1:1) and say whether it's in inches or millimeters.
- One part per file, or clearly separated parts with a note on how many of each.
- Closed shapes only. Every outline and hole should be a closed loop with no gaps or overlapping lines.
- Remove extras. Dimensions, title blocks, center marks and hatch patterns can end up as cut lines. Put them on a separate layer or leave them out.
- Mark bend lines on their own layer if the part gets formed after cutting.
What to include with the order
- Material (mild steel, stainless or aluminum) and thickness
- Quantity, and whether it's a one-time or repeat order
- Any holes that must hit a tight size, like bolt holes for a specific fastener
- Whether the parts need bending, welding or a finish
- When you need them, and pickup, delivery or shipping
Design tips for plasma-cut parts
- Small holes. As a rule of thumb, plasma holes should be no smaller than the material thickness. Smaller holes come out tapered or undersized and are better drilled after cutting.
- Bolt holes that matter. If a hole has to be exact, say so on the drawing, so it can be cut undersize and finished to size.
- Lettering. Letters like O, A, B, D, P, Q and R have centers that fall out. Use a stencil-style font with bridges, or tell us to add them.
- Thin details. Very narrow strips and sharp inside points can warp or burn away. Keep features at least a little wider than the material is thick.
- Edges. Plasma leaves a slight bevel and can leave some dross on the bottom edge. If an edge is a sealing or precision surface, mention it so we plan for it.
