Method for machining metallic member using lathing and scraping

摘要

A metallic member includes a top portion and a peripheral sidewall, is positioned on the worktable. The worktable is rotated with the metallic member, the lathe tool reciprocates to machine the top portion of the rotary metallic member circumferentially. The lathe tool is moved along a predetermined path relative to the worktable by the moving device to machine curved surfaces of the top portion of the metallic member. The scraping cutter is moved to contact the peripheral sidewall of the metallic member. The scraping cutter is moved along a predetermined path, and the scraping cutter is fed the metallic member to achieve the required shape and finish.
