Here is an assortment of tips for designing parts in Sketchup that will later be cut out with a CNC-Machine. These tips aren’t in any particular order. I just put them up as I think of them.
Here is a quick tutorial for making tabs in Sketchup. Tabs are useful because they help hold the part that you are cutting in place. That way, it won’t accidentally get caught on the router bit causing the part to be damaged or possibly causing the CNC machine to lose steps.
This page will cover the reasoning for why making parts in a Sketchup model perfectly identical when designing them to be cut out with a CNC is a good idea.
This page will cover the reasoning for why making parts in a Sketchup model symmetrical is a good idea. A symmetrical part essentially means that, if you were to draw a line directly through the center of it, both halves would be exactly the same.
Here is a very quick tip for creating Sketchup models which involves the simple circle. When drawing one, make sure that you use the radius and not the diameter…
This page will cover some of the ways to find the models in the Sketchup 3D Warehouse that are useful for CNC projects.
When designing a part that will be cut out with a CNC, it’s important to remember that router bits cannot reach all the way into the corners. This tutorial will show you how to compensate for this.
