The way I think, 180 degrees makes a half ball, and 360 makes a full ball (and would cause it to fall of as you said). So I would like to write code that is capable of cutting more than 180, but less than 360 degrees. >> One more question: when making a part without a tailstock, I have to >> be double sure that the part is as rigid at any moment as possible. >> So, it would make sense to program things to use something like a >> cutoff bit to rough out the part by removing as much material on the >> farthest end as possible, and then moving slightly close to the chuck >> and repeating.
