In this thesis, several machining strategies to remove axially symmetric form error with small wavelength
by Hydrodynamic Polishing process (abbreviated as HDP) were proposed.
Three strategies were proposed progressively in the study so as to remove axially symmetric form error
with small wavelength. The first and second tactics were based on a basic algorithm, say, directly solving of a
set of simultaneous equations. In the first strategy, a set of simultaneous equations was constructed by relating
the total machining action of each dwelling point to the corresponding initial error. Subsequently, a set of dwelling
time was obtained by directly solving the simultaneous equations. The second strategy evaluates solutions in a
similar way like the first one but more restrictions were concerned in solution evaluation. The third strategy is
an optimal based method. A set of dwelling time was obtained by minimizing an objective function with given
constraints.
A series of computer simulations were conducted to estimate the residual error and examine the validity of
the strategies. From the computer simulation, the first and second strategies were confronted with negative-time
problem, so that merely limited improving of form precision was obtained. The proposed optimal strategy was
shown to have high potential for improving the machining precision by the HDP process. Based on the proposed
strategies, a better form precision of the work surface with small wavelength can be obtained.
