Surface roughness of ceramic cutting tool machining ductile cast iron and machine vibration research

High speed engraving and milling machine processing in the process of ductile cast iron with ceramic knives cutting tool life, surface precision and the influence of vibration on the surface accuracy. Test on multiple rotation speed, feed and cutting depth of the compound. Of vibration on the radial cutting direction and the flank wear is studied. Vibration measurement is to use two accelerometers is connected to the clamp, is used for the parameters of the corresponding surface roughness amplitude and acceleration signal. The test results show that the alumina ceramic cutting tools are not suitable for processing and nodular cast iron. In the 364 - 685 m/min speed range, the largest life just is 1. 5min。 Used in cutting conditions, as the flank wear surface accuracy is almost constant. Experiments also observed that in the process of cutting the same flank wear, shock, and decreased with the increase of velocity. Even under the condition of small cutting depth, vibration and flank wear is almost constant.
