I'm not familiar with Visual Mill, but here's a way I've run roundover cutters that should work with any Cam program assuming you want to cut a full quarter round and not just use the tool to break the edge. Set the tool diameter to the core diameter of the roundover cutter, and set the depth of cut equal to the roundover radius, with the tool length based on the bottom of the cutter. The profiling path would then be based on tracing the previously cut profile without taking off any more material. Sometimes if there's not a straightforward way of doing things, you just have to trick the software and machine into doing what you want it to do. |
