Application of Computer Simulation in Metalcasting Course

Abstract

Modern developments in computer technology and computer software have allowed simulation of very complex physical phenomena, which was almost impossible or prohibitively expensive even several years ago. One such area is fluid flow involving heat transfer and coupled with phase transformation. The problem is very difficult as it sounds, but nowadays one can obtain very good results even on a personal computer within a reasonable period of time. The manufacturing process that belongs to this group of problems is metalcasting. In the past, metalcasting was more of an art than the science; however, nowadays computer software is successfully applied to simulate filling and solidification process. The accurate result of simulation allow improved casting design along with the optimization of the gating and risering system used to produce a sound product.

Introduction

Tremendous developments in computer science, engineering and technology in recent years have brought many changes in the way we conduct our daily activities. Computer speed and memory has been increased, and continues to increase at a very fast pace, allowing us to use them for very complex and complicated applications. Computers are used for real time simulation and control of very fast dynamic systems, and computers are now commonly used to analyze very complex structures and processes. What seemed impossible, or nearly impossible some ten years ago, is a reality today, and the scope of potential applications is ever increasing, and the accuracy of computer generated solutions is constantly improving.

The computers have played and continue to play a very important role in the manufacturing processes, from the design of parts, to manufacturing production planning. They are resulting in improved products and reduced production times, which all lead to a more satisfied customer and thus in an increased competitiveness for both manufacturer as well as the end user.

Metalcasting is one of the oldest and also one of the most complex manufacturing areas. The metalcasting process has been known for over 10,000 years, and today it still has the same basic characteristics as it had when our ancestors where casting small decorative pendants and beads. However, in the meantime, metalcasting industry has evolved from purely art to a very scientific type of manufacturing process. Foundrymen have been learning on their own as well adopting
