Parametric modeling approach for refiner plate design and production

摘要

Parametric/feature-based design is a modern approach for product modeling to save time and money during the product development and manufacturing process, especially in the preliminary stages of design. Parametric modeling can be used to improve customer satisfaction by facilitating rapid product customization and achieve specific customer requirements. In this paper, a parametric/feature-based modeling approach that is being developed to facilitate design verification, reduce lead-time and improve product customization when designing and producing a variety of refiner plate patterns for sand casting is discussed. The primary focus in this paper is on formalizing the parametric modeling approach and comparing its implementation in two CAD modeling systems. A comparison of the cost and product lead-time using the proposed solid modeling approach and the traditional 2D drawing approach to generate a CNC machined pattern for sand castings is also presented.
