| Summary: | The objective of the present study is to justify the
possibility of constructive and analytic solution to
the inverse problem of cyclographic modeling of a
curve of space R3
and development of a respective
algorithm. The orthogonal projection and the two
components of the cyclographic projection of a spatial
curve form a triad of elements in plane z=0. These
elements are the result of the direct problem solution
and constitute the basis for the inverse problem
solution. The direct problem consists in construction
in plane z=0 of a cyclographic projection (a model)
of a given spatial curve, while the inverse problem
consists in determination of a spatial curve given its
cyclographic projection. Insufficient knowledge on the
inverse problem as well as its relevance in practical
applications, e.g. in cutting tool trajectory calculation
for pocket machining of mechanical engineering
products on NC units, make urgent the definition and
the solution of the inverse problem. In the present
paper a simple convex closed curve is considered as the given cyclographic projection. It is proven that there
exists a unique spatial curve, for which the given curve
constitutes a cyclographic projection. The algorithm
for the inverse problem solution is demonstrated on
examples. |
