Milling is the process of machining flat, curved, orMilling machines are basically classified as vertical or irregular surfaces by feeding the workpiece against a rotating horizontal. These machines are also classified as knee-type, cutter containing a number of cutting edges. The milling ram-type, manufacturing or bed type, and planer-type.

Rollin Technique MoldMaking Technology. Apr 01, 2013 When using the rollin technique, thin chips will exit the cutter from the very start of the machining process, regardless of milling cutter center line position This eliminates the tool pressure fluctuation, and loading and unloading of the machine spindle bearings In the end, the rollingin technique not only eliminates the vibration

So it was the basic process of mill turn that made me want to re-design everything for that process. - ability to scale efficiently. So the Gildemeister CLX 450 TC - B axis mill turn would be interesting, as it's a literal knock off of a Mazak J-200 AND seems they have gone to town to make things simple and reliable on the control. Like MAZAK.

Ive been Machining about 10 years now and wish someone would have told me sooner. I went to a modern art of milling class and they went over all this. It was shown in the class that when making multiple passes to stay in the cut and roll the corners instead of sharp corners. I think id take several depth passes.
