  • A flexible force model for end milling of low-rigidity parts

    Nov 10 2004 · Peripheral milling of flexible (low-rigidity) components is a common manufacturing process in the aerospace and power industries. The process is complicated by periodically varying milling forces which statically and dynamically excite the tool and part structures leading to significant and often unpredictable deflections.
