Automatic manufacturability evaluation method and system

U.S. Patent Number: 5717598

Abstract: A designed object workability evaluating system for evaluating quantitatively at a stage of designing an article whether a structure of the article as designed can be realized easily in a manufacturing stage for thereby selectively determining a best structure from a plurality of design plans through comparative evaluation thereof. The system includes a client machine section including a guide information generating unit for generating information for guiding operations of a user, an input device for allowing the user to input commands and data and a display unit. A server machine section includes a registering unit storing evaluation elements defined by the user, an index calculating module for calculating indexes indicating degrees of difficulty/ease of work, an evaluation element estimating module, a part workability evaluation module, an article workability evaluation module, and a best design plan selection/determination module.
