Influences of Turning Parameters on Surface Roughness in Ultra-precision Diamond Turning Processing Technology

摘要

Complex surfaces can be manufactured by using ultra-precision diamond turning processing technology, whereas the surface roughness of the workpiece is influenced by many factors, the relationships among these factors are very complex, and little research reports are found. In this paper, influences of the turning parameters on surface roughness are investigated and analyzed under different related parameters such as spindle speed, feed rate and depth of cut. The result shows that the slotted tool could obtain better surface roughness than the non-slotted tool under the same conditions. Through changing the magnetic field intensity, finishing gap, rotational speed of tool and finishing time, an orthogonal experiment is conducted to obtain the optimal finishing process parameters.
