Abstract
During all steps of product life cycle, especially at the design level and manufacturing level, a coherent model for functional geometry of the product is required. The inherent imperfections of manufacturing processes involve a geometrical deterioration of functional geometry of the product, and therefore of its quality.
This paper introduces a model by Gauge with Internal Mobilities that allows representing
-
the standard geometrical speci fications of a part.
-
the manufacturing process capabilities.
The approach by Gauge with Internal Mobilities establishes the domain of acceptable variations of the non-ideal geometry, starting fiom two concepts:
-
the interface gauge / part defining the relative position between the ideal features of the gauge and the non ideal features of the part,
-
the gauge structure modeling the environment of the part.
The main interest of this approach is that the same description model is proposed for both the standard geometrical specifications and the manufacturing process capabilities. In the companion paper, the validation of the process plan is proposed, the validation method consists in comparing the manufacturing capabilities to the standard geometrical specifications.
