Iso-scallop tool path building algorithm “based on tool performance metric” for generalized cutter and arbitrary milling zones in 3-axis CNC milling of free-form triangular meshed surfaces

In order to generate a tool path, scallop height should be under the given precision requirement and the tool path should be as short as possible. Iso-scallop tool path generation method is traditionally used to generate the effective tool path. This paper discussed a new method to generate a iso-scallop and contour-parallel tool path for a generalized cutter and an arbitrary area on free-form surface in 3-axis CNC milling. The milling surface,...
