Matt,
There are several options available for spiral toolpaths in MC, particularly under the surface/rough/pocket area. I think there's a spiral option under high speed toolpaths as well. I never used this option so I'm not sure. In the surface/rough/pocket area you have........true,parallel,overlap,and morph spiral options. Keep in mind these are roughing toolpaths and not intended for achieving a decent surface finish. I'm sure you can adjust some settings to achieve this but you get the point. If your trying to achieve a spiral type toolpath as a finishing path you could use the scallop option. You can set the start point at the center of your part and it will create a toolpath in an outward circular pattern from that point, very similar to a spiral. I'm no expert in MC and I'm sure more options are available. I'm only sharing what I know. When I machine wood (MDF) I usually use a .050" stepover and a .020" stepdown. This may seem a lot but I usually cut large pieces and these parameters cut down on machine time. Since its MDF were talking about, there is no way to achieve a metal type surface finish with any toolpath option. Once you cut past the surface of MDF the material becomes grainy, its smooth but grainy. After the part is machined..... a little sanding is necessary. The parts I create are intended as a plug which then are used to create a fiberglass mold. After the mold is created the mold is sanded and buffed to a mirror finish. Its much easier to work on the mold than the plug. |
