The problem of end mill bit when working

Since there is a slight clearance between the end mill bit and the holder, so in the process tool vibration phenomena may occur. End mill vibration causes uneven circumference edge of cut, and cut expansion than the original value increases, the impact of precision and tool life. However, cutting wheel when the machined groove width is too small, the tool may be purposefully vibration, to achieve the desired groove width by increasing the amount of cut expansion, but the maximum amplitude of the end mill should be limited to this case 0.02mm or less otherwise, can not be stable cutting. In the normal processing of neutral end mill cutter vibration as small as possible.

When the tool vibration, you should consider lowering the cutting speed and feed rate, as both are still large vibration is reduced by 40%, you should consider reducing the amount of cut.

Such as the processing system in the resonance, the reason may be too large cutting speed and feed rate cutting blade is small, due to less rigid tool system, workpiece clamping force is not enough and the shape of the workpiece or workpiece clamping methods and other factors, and you should be taken to adjust the cutting dosage, increase tool system stiffness, increase the feed rate and other measures.
