Abstract
In order to give product competitive strength, it is an important point to shorten a development term. The manufacture cost estimated system using 3D-CAD data offers the environment of the design review which used the manufacture cost as the base in the Design Revue. After all shortening of a product development term can be aimed at. There are four descriptions of this Cost Estimation System. The 1st is that estimation parameter is acquired from 3D-CAD data. It is that the 2nd attained automation of process setup-man hour calculation-cost calculation. It is the 3rd having had estimated criteria data used by the estimate in the external database, and having raised flexibility. he last is the function which unites with estimated criteria and generates automatically a part for the calculation function part of a source program.
