LaserScript 6040 vitesse/puissance. CNC Panel Joinery Notebook. I’ve been collecting clever ways of slotting flat stock together since I first read Nomadic Furniture back in 1999, well before the advent of the accessible hobby-class CNC tools that, today, make manufacturing parts like these pretty easy.

CNC Panel Joinery Notebook

Now, the world is full of people designing models, project enclosures, sculpture, furniture, and all kinds of other cool stuff to be assembled from parts made on laser cutters and CNC routers, and I keep expecting a definitive book or website to emerge that covers the “bag of tricks” in an organized way. So far, I haven’t found it. I may have missed it. Or maybe this article can serve as a jumping-off point. In any case, I think it’s time to open up my file. In presenting this material, I want to first acknowledge my respect for the world’s established and ancient traditions of joinery. I may abuse some terms, without meaning to, and I am glad to be corrected by those who are in the know about traditional joinery. Laser vs. Biasing Cross (“X”) Joints. Laser cutting materials, laser engraving materials. ‎www.ocadu.ca/Assets/pdf_media/ocad/about/shops_studios/rp_centre_illustrator_tutorial.pdf. Preparing Illustrator drawings for the Speedy 300 laser cutter.

This tutorial will show you how to prepare your drawing for the laser cutter.

Preparing Illustrator drawings for the Speedy 300 laser cutter

I assume that you are using Illustrator CS3 to create your drawing. In addition to Illustrator, you also need to have Corel Draw, which you can download from the TU/e website. You may also to consider to work directly in Corel Draw, since it can also import EPS files, however, you may miss the creative power of Illustrator. We have a Trotec Speedy 300, which has an accuracty of +/- 0.0025mm, which makes it an excellent tool to cut wood, plastic and paper.

Metal cannot be cut and not all plastics are suitable.

How much material does the laser burn away? In 2008 I sought to try and quantify the kerf of our laser cutter, or how much material the laser cutter burns away when cutting specific materials.

How much material does the laser burn away?

The idea behind providing this information is so you can make a more educated guess of what sizes to draw your shapes if you are needing a tolerance fit. This information is particularly relevant if you are creating inlays and slotting joints*. Please note that these are old figures, which we are hoping to update soon – we cannot guarantee super-precise kerf widths at this time. Prototyping for yourself is the best way to guarantee the perfect result but hopefully this info will give you an idea of what to expect. So anyway here are the results… For those using imperial: And for those on the metric system: So what does that mean? If you were to draw some parts to be cut from 3mm acrylic as dimensioned below, the white square on the right would end up at 39.80mm and the hole in the middle of the red square would be 40.20mm.
