WebThe thread milling operation is based on three-axes simultaneous movement so the profile shape on the workpiece is not a copy of the insert profile. In other words the profile is generated and not copied which is contrary to the thread turning operation. This fact causes a profile distortion, especially when machining coarse pitch internal threads.
