If one pass didn’t go deep enough to clean and flatten the spoilboard simply Z zero the bit to the new surface and run the same toolpath again.Komanduri R, Lucca DA, Tani Y (1997) Technological advances in fine abrasive process. Zero it in the X, Y and Z axes and run the fly cut toolpath.Īdmire your freshly cut spoilboard. Changing it from 0 to 90, or 90 to 0, changes the cut from the X direction to the Y direction, or vice versa. Running the toolpath parallel to the long dimension of the spoilboard is slightly faster than running it parallel to the short dimension.Ĭhange the direction of the cut by changing the raster angle. Select the toolpath and check what direction the fly cut is running. Select Raster and Ramp Plunge Moves and click Calculate. 020” and choose the cutter you’ll be using. Select the rectangle you created and choose the Pocket Toolpath. Use the Draw Rectangle tool to create a rectangle that is 1” larger than the spoilboard, and centered on the spoilboard. In Job Setup use the size of your spoilboard as the Job Size. The design and toolpath work shown here is done in VCarve Pro. These bits can also be used to flatten slabs, cutting boards and other projects on your CNC. But you’ll appreciate the way larger bits, 1-1/2” (middle), or 2” (right), get the work done more quickly. That being said, a 3/4" straight bit, left, will provide the same results as a larger diameter cutter. ![]() Nearly any flat bottom bit can be used for fly cutting, but a large diameter bit will allow the work to go faster because it requires fewer passes. ![]() It’s important to know the exact thickness of your material to get this right, and you can’t beat digital calipers for getting that precise measurement. 020” more than the material thickness is plenty. Minimize the frequency of needing to fly cut the spoilboard by cutting as little as possible beyond the workpiece. ![]() When using your CNC you will, in all likelihood, periodically cut all the way through your pieces. It can also refer to the work you would do to level a piece of stock like a large slab that still has sawmill marks in it. This guarantees that the surface of the spoilboard is perfectly parallel to the travel of the spindle.įly cutting is the process of leveling the spoilboard to make it flat again. You should also fly cut the spoilboard on a brand new CNC machine. When your spoilboard starts to look like the surface of the moon, or a small-scale version of that, it needs to be fly cut. Not in the sense that you’ll throw it out and get a new one, but in the sense that your toolpaths will cut into it and, over time, the surface of the spoilboard will be far from flat. This flycutting makes the board open and porous enough to accept the vacuum. The spoilboard on your CNC router is a disposable commodity. The first step in optimizing vacuum is to make a 0.5mm flycut on both sides of the raw MDF.
