Numerous works have shown that the linear format of tool path is not well adapted to HSM for it does allow an optimal follow-up of the tool trajectory by the NC unit, nor a good part surface quality. This paper deals with formats of tool trajectory relying on polynomial models. The tool path can be described as polynomial curves as well as polynomial surfaces. Geometrical and dynamical advantages of using such formats are exposed.
