Improved Foundry Castings Utilizing CAD/CAM (Computer Aided Design/Computer Aided Manufacture). Volume 1. Overview

摘要

A software package, UPCAST, has been developed as an aid to casting engineers in designing and analyzing the manufacturing process for high integrity steel castings. The UPCAST routines use (1) computer graphics and computer assisted computations relative to heading and gating and (2) evaluation routines that allow 2-D and 3-D heat transfer analyses with a minimum of interaction from the user. Extensive experimental work was performed to validate the computer programs, to collect thermal properties needed for modeling steel castings in sand molds, and to predict casting soundness. Volume I presents an overview of the project and the UPCAST software. Keywords: Computer assisted manufacturing (CAD/CAM), Castings, Steel, Molds, Heat, Flow, Fluid flow, Finite Element, FInite difference, Casting soundness. (jes)
