Development Of Simultaneous Twin Cutter For Machining Thin-Wall Component

Peripheral milling of very flexible components with a large span ratio of heights to thickness such as monolithic component is a common manufacturing process in the aerospace industries. In such cases, the wall thickness of the part is further reduced, leading to dimensional surface error that cause...
