When cutting a 3d model, I am having trouble deciphering which ball nose bit for finishing toolpath. Is there a more mathematical approach to choosing what size ballnose to use for finishing? For rough cutting? Or is looking at the preview screen for definition the only way to choose?
Also,
When I create a boundary profile for each 3d model slice, how can I make sure that I don't cut all the way through while doing my roughing and finishing passes, in order to hold the material down until I run the profile pass. Once achieved, how do I then incorporate tabs that will not be removed with the roughing/finishing toolpaths? Thanks, Marc
