<p><P>PROBLEM TO BE SOLVED: To effectively conduct design work as to a machine product while taking its production into a view field. <P>SOLUTION: A production model 100 for expressing the product, a type model 200 for expressing a type for forming a rough shape of the product, and a working model 300 for expressing a worked portion of a portion removed from the rough shape by mechanical work are controlled centralizedly in a design and production control part 10. Each of the models 100-300 is related with attribute information for expressing a requirement (for example, used working tool, surface roughness to be realized, and the like) on the production in a portion corresponding to each constitutive element of each three-dimensional solid model, to the element, using the three-dimensional solid model for expressing a shape as a core. Element models for expressing the type and a standard portion in the worked portion are registered in the design and production control part 10, and the proper model is retrieved, when designed, to be arranged to the type model 200 and the working model 300, so as to specify the considerable portions in the models. <P>COPYRIGHT: (C)2003,JPO</p> |
