We can adjust for kerf by doing some additional work right before exporting: Sometimes this doesn’t matter, but for parts that must precisely fit together (like the ubiquitous finger-jointed boxes) it can be an annoying problem. The principal shortcoming of this approach is that the projected contours aren’t adjusted for the kerf of the laser cutter. Create a new sketch and project all parts on the cut layout to the sketch plane.Arrange the parts as desired, generally to minimize waste. Copy each body to be laser cut to a new component called ‘cut layout’ or similar.Arrange bodies into ‘components’ as appropriate. Model your project as for any other media.

Taylor demonstrated it at one of his Fusion 360 workshops, and I’m sure more information can be found with a web search. It’s always been possible to use Fusion 360 to develop projects for our laser cutter. For non AMT readers, our laser cutter seems to be very similar to the RL-80-1290 sold by Rabbit Laser. These notes apply to our EXLAS 1280 laser cutter, which is driven by Lasercut 5.3 and accepts a DXF file as input. I recently experimented with this feature, and thought I’d write up my findings. Fusion 360 now has an experimental CAM feature to develop cutting paths for a laser cutter.
