An interactive computer program has been developed to design a pattern and risers for the production of castings of high quality. In our system, the user models the shape of a final product by using the system's modeling capability, a pattern is generated in a three dimensional model by eliminating the holes and adding shrinkage allowances and drafts, the proper riser is created automatically, and they are united together to yield the three dimensional model of the portion of a mold assembly. The mold can be completed after the runners and the gating systems are designed, modeled, and united, which will be described in part 2 of this work. The unique feature of this work is a realization of an automatic design of the pattern and risers by integrating the modeling capabilities and the design equations used in the real practice.
