A Mold Requirement Check Tool That Enables the Quality of Mass-Produced Parts to Be Established Early in the Development Process

At Fuji Xerox, after we issue engineering drawings for parts, we outsource the design and manufacture of the molds for those parts. In the past, technical know-how on molds was not accumulated in Fuji Xerox, and mold requirements often were not sufficiently reflected in the designs and drawings of the parts. In many cases, Fuji Xerox engineers had to make changes in the designs and drawings of parts in order to reflect mold requirements after the drawings had been issued, increasing the lead time required for the manufacturers to design and manufacture the molds. To address this, we introduced a fundamental change in the product development process in order to ensure that mold requirements are sufficiently reflected in the designs and drawings of parts before the drawings are issued. To achieve this, we utilized our 3D-CAD data feature recognition technology to develop a "mold requirement check tool" that checks the 3D-CAD models and automatically detects and specifies any nonconformities with the mold requirements. As a result, we succeeded in reducing the number of modifications made due to trouble occurring in molds after the issue of the drawings. This paper describes how and why we decided to develop the check tool, the background of its development, the technologies used, an overview of the tool, the effects of its introduction, and future plans for the tool, such as providing it to other companies as a solution service.
