4/9/2023 0 Comments Flycut copperYou can see that auto body filler provides a great way to level overly deep cuts without removing excessive material from the spoilboard. If one pass doesn’t level the spoilboard simply rezero the Z and run the toolpath again. You may need to reduce the size of the rectangle you created for the Pocket Toolpath. If you get a warning that the X or Y is Out of soft limit, double-check the XY zero. Install the router bit and zero the Z axis. It can be hard to zero the X and Y axes with a large diameter bit mounted in the spindle. You’ll need to flycut the spoilboard multiple times in the life of your machine, so save the toolpath. It won’t look like much, but you can see where you’re at and make necessary changes. 020” beyond the thickness of the material, so a flycut depth of. When you do through cuts on your CNC you should only cut. 025” and choose the endmill you’ll be using. Thickness isn’t important.Ĭreate a rectangle that’s 5/8” larger than your spoilboard.Ĭenter the rectangle on your workpiece/spoilboard. If that’s the case with your machine multiply the number on the display by 60 to get rpm.Ĭreate a new job and use the size of your spoilboard as the Job Size. Remember that most CNC machines read in hertz, not rpm. If you’re using a large diameter bit reduce the rpm of the spindle. It’s the same bit I use to level epoxy pours, end grain cutting boards and slabs. My flycutting bit is 2” diameter and has carbide insert cutters. Any endmill can be used for this job but, of course, a larger diameter bit will get the job done much faster. Follow the mixing directions and give the filler plenty of time to dry.Ĭhoose your bit. My big overcut is way more than that, but I don’t want to flycut the entire spoilboard to get down to that level.įill extra deep cuts with auto body filler. Most of the “normal” cuts in the spoilboard are only. Ouch! I messed up a toolpath and WAY overcut into the spoilboard. In addition to leveling, flycutting ensures that the face of the spoilboard is perfectly parallel to the travel of the spindle. Over time the spoilboard starts to look like the surface of the moon and needs to be leveled, also called flycutting.Įven a brand-new CNC router needs its spoilboard flycut. As you use your machine and do through cuts on projects you’ll cut (slightly) into your spoilboard. The output of prediction model helps to select cutting parameters to reduce surface roughness which ensures surface quality in ultra-precision fly cutting machining.The spoilboard on your CNC needs to be dead flat, unlike this one. Experimental results demonstrate that the prediction model is adequate at 95% confidence level. Finally, validation tests are conducted to verify the model. Furthermore, the effect of cutting parameters upon the surface roughness is analyzed. After that, the prediction model is obtained by analyzing the experimental data, and the accuracy of the model is verified by analysis of variance (ANOVA), R 2 value and residual analysis. Then, a machining experiment for the copper is conducted under different cutting parameters designed by Taguchi method and the surface roughness is tested by 4D technology dynamic laser interferometer. Based on the processing principle of flycutting machining, the prediction model for surface roughness is set up by response surface methodology. To improve the surface quality of the copper and reduce the diamond tool wear, a prediction model is established experimentally for the relationship between surface roughness and machining parameters.
