1. The impact of milling vibration on machining accuracy. Milling vibration is caused by factors such as the interrupted cutting characteristics of milling, the milling method (down milling or up milling), and the rigidity of the process system. Milling vibration directly affects milling accuracy. 2. The multi-blade tool cuts into the surface of the workpiece intermittently, and the cutting force changes continuously when the precision parts are processed, which causes the periodic vibration of the process system. 3. During up-milling, there is a slip distance when the milling cutter cuts into the machining surface of the workpiece, which causes the tool bar to rise. After cutting into the machining surface, the tool bar is pulled down, causing periodic milling vibration. 4. The vibration of the milling machine caused by the clearance of the spindle, worktable guide rail, transmission mechanism, etc., affects the processing accuracy. 5. Milling machine fixtures cause milling vibration due to insufficient rigidity during milling. 6. Long milling cutter shank, large milling cutter diameter or length dimensions cause milling vibration. 7. Insufficient rigidity of the workpiece, or improper positioning or clamping causes milling vibration.
