Causes and Solutions of Vibration Marks in Milling Process

Vibration lines appear in the milling process and the solutions:

① Feed and cutting speed are too fast Correct the feed and cutting speed

Solution: Correct the feed and cutting speed

②Insufficient rigidity (machine tool and tool holder)

How to solve: use a better machine tool holder or change the cutting conditions

③The rear angle is too large

Method: Change to a smaller relief angle/machined margin (grind once with a whetstone)

④Clamping loose (workpiece)

Method: Clamp the workpiece

⑤ The cutting is too deep, solution: Correct the cutting depth to a smaller depth

⑥ The force length and total length are too long

The shank clamp is deeper, use a short knife or change the cutting conditions
