Sculpture surfaces are extensively used in designing complex shapes such as automobiles bodies, turbine blades and etc. As the great deployment of CAD/CAM software and application of them in industries, the problem related to machinability (machining time, surface roughness and...) have large importance. In this paper first we introduce 3 algorithms that used by CAD/CAM software for machining this type of surfaces and the comparison between them , then with an experimental comparison upon machinability we will offer the optimum algorithm for machining of sculpture surfaces.

Sculpture surface, tool path, Iso-parametric, Iso-planar, Iso-scallop
