Abstract: Triangular
mesh surface gains wide applications in industrial field. However, the
tool path generation methods for polyhedral machining are very limited
and the isoplanar method is still the common used method. A conformal
map based isoparametric method for kinematic path generation is
proposed. Through establishing the parametric relations between the
triangular meshes embedded in the 3D space and the rectangular or
circular region on the 2D plane, zigzag or contour paths are finally
implemented by inversely mapping the planar iso-parametric paths into
the physical space. Also, the issues of CC point and side interval
calculation as well as interference detection are discussed in detail.
The results show that the proposed method is boundary-conformed and can
improve machining dynamics and efficiency in most cases.
