  • Evaluation of shape complexity based on STL data
    Valentan, Bogdan ...
    The objective of this paper is to present the complexity of a part, based on basic information of the STL data. A few methods for the evaluation of shape complexity are presented. Methods vary from ... very simple ones based on the number of triangles in the STL file and the parts volume to more complex mathematical determination based on the relations of the basic STL data. We discovered that the evaluation of shape complexity based only on basic STL data gives us some basic view on part complexity. For parts with large block volume/part volume ratio and thinner parts with free form surfaces only the first method is suitable and gives us suitable results. The complexity of the shape of a part is an important factor for all manufacturing procedures. When using conventional machining, the parts complexity presents the key factor in determining the optimal way of manufacturing. Also, when using rapis tooling, the complexity of the part determines the parting plane laypout and eventual tool construction. Even when using certain rapid prototyping procedures, the support material consumption depends highly on the complexity of the part and together with the problem of optimal orientation and position of the part, significantly influences the manufacturing costs. A few test methods that try to determine the complexity with respect to the manufacturing procedure used for the part are presented. Choosing the maximum efficient manufacturing process on the basis of part complexity is a new perspective in manufacturing, which may cause a revolution in manufacturing optimization, especially in hybrid manufacturing processes.
