Simulation of Surface Topography in Diamond Turning under the Effect of Vibration

摘要

In this paper, a surface topography simulation model of ultra-precision machining which incorporates the important factors such as tool geometry, cutting parameter ( including feed speed and cutting depth) and relative motion between the cutting tool and the workpiece is established to study the effects of vibration on the surface topography. Trimming phenomenon of cutting edge profile is also analyzed at the radial section of the workpiece by the simulation program. It is experimentally shown that good effect is obtained by using the model to simulate surface topography of ultra-precision face turning. The model can also be used for simulating the traces of tool motion, predicting the three dimension microscopic surface topography and two dimension surface profile, and optimizing the cutting parameters of diamond turning process.
