System and Method for Identifying Defects of Surfaces Due to Machining Processes

摘要

Embodiments of the invention disclose a method for determining defects of a surface of a model of an object generated from a model of an original object by a simulation of a machining process. The method determines orientations and rate of change in the orientation of the surface based on normal vectors to the surface and identifies the defects of the surface based on the rate of change and a threshold. The threshold is determined based on the machining process.
