| Abstract |
With the correlation in stochastic process applied to the experimental results, the surface
during grinding and further lapping with abrasive jet finishing (AJF) restricted by grinding wheel was
investigated with respect to auto correlation function (ACF) , cross correlation function (CCF) and
power spectral density (PSD) analysis. The results indicated that AJF made the surface contour
formed periodicity in a small range and removed fluctuation of the surface contour in low frequency
greatly. The average spacing of the surface contour decreased and the machined surfaces changed
from continuous parallel micro-groove and plough to randomly distributed discontinuous micro-pit
with the increase of machining circles. The surface texture became fine and surface roughness was
obviously improved. Furthermore, the isotropy surface and uniformity veins both parallel and
perpendicular machining direction was attained by the finishing process to improve greatly the
wearable capability of the workpiece. |
