Manufacturing feature is key information to achieve data sharing between CAD and the following manufacturing process. It is well known that the data of the feature is first generated by feature recognition from CAD geometry, and then applied to the process planning. Our study has examined the process planning based on Feature Dependency and have demonstrated the way to create and implement the feature dependency. First report demonstrates that representing the feature dependency which contains feature hierarchy when applying the data to the process planning leads the following process to be more efficient and accurate. In the second report, features including division and/or unification, i.e. dynamic feature, are discussed. Previous two papers focus on the features which have explicit relationship with geometry, i.e. explicit feature, are discussed. In this paper, feature dependency that has no explicit relationship with geometry, i.e. implicit feature, such as a thread, surface finish, removal thickness and finishing allowance are also discussed and the method of integrating explicit features and implicit features into one feature dependency is introduced.
