چکیده
This paper presents MEDIATOR, a feature recognition system which is designed to be maintainable and ex-tensible to families of related manufacturing processes. A problem in many feature recognition systems is that they are diicult to maintain. One of the reasons may be because they depend on use of a library of feature-types which are diicult to update when the manufacturing processes change due to changes in the manufacturing equipment. The approach taken by MEDIATOR is based on the idea that the properties of the manufacturing equipment are what enable manufac-turable shapes to be produced in a part. MEDIATOR's method for identifying features uses a description of the manufacturing equipment to simultaneously identify manufacturable volumes (i.e. features) and methods for manufacturing those volumes. Maintenance of the system is simpliied because only the description of the equipment needs to be updated in order to update the features identiied by the system.
