Process limitations
- [Instructor] Every production process has its limits and laser cutting is no exception, physics being the main limiter. Laser cutting works best with consistent material thickness and composition. Unfortunately, all materials, especially organic ones, will have some variance. If your work piece if warped, the laser cutter does not yet have the brain to accommodate height changes. The laser cutter is assuming that it is cutting a flat piece of sheet material. Designs will be compromised if the workpiece cannot be made flat with weights or vacuum assistance. To combat warping, store all stock materials flat in a humidity and temperature controlled environment and avoid getting moisture on porous materials. I have to tell you something. Many materials that state dimensions are actually listing nominal or approximate dimensions. It's very upsetting, I know. At least two measurements are needed to get an accurate actual sheet thickness. Armed with this data, you can program the laser…
