The purpose of this thesis is to built a set of deviation
analysis modelso as to construct a prescribed applyin g on the
deviation analysis betweena prototype and a product during the
Rever se Engineering process. Furthermore,the information (data)
obtained from the deviation analysis can be used tocomplete a
finished machining on the workpie ce or to proceed the
subsequent amendment on CAD model. A
first step of the deviation analysis is to form a basis with
respect to the comparison between the product and the prototype.
Then, a transformation matrix is obtained and used to proceed a
coordinate transformation on the point data from the prototype
to the product in accordance with the same coordinate system
therebetween.The subjects of this thesis comprises:(1)
proceeding the ante-process on the point data and constructing
the B-spline surface;(2) determining the required inspection
points of thdeviation analysis according to the statistics;(3)
applying Simplex method mated with the least squareroot method
to obtain three translation parameters and three rotation
parameters; and (4) proceeding the deviation analysis and
showing the tolerance values. In addition to the discussion on
the basic theory and algorithm, the present thesis submit with
the experimental data to support the feasibility thereof.
