Milling vs. Grinding - obsidianmfg
Milling says: Provide enough material for a good machining cut.When the tool must make a scale cut, the effective lift of the cutting edge is reduced. Bear in mind that you do not always reduce machining time when you leave little stock; you may in fact be losing time and money as a result of excessive cutting edge wear.
