COMPUTER-ASSISTED IMPLEMENTATION OF POWDER FORGING PROCESSES
Computerized methods have been developed for powder preform forging processes to reduce the trial-and-error development required for preform design and to improve dimensional control in the finished parts. First, the part volume and volume distribution are calculated from digitized input of the drawings. Die dimensions are then calculated including thermal and elastic effects. Shrink ring dimensions and interferences are also calculated if required. Preform design is then accomplished using an interactive computer program that includes consideration of densification, cracking limits and die chilling. At the present stage of development, some user decisions are necessary and previous experience is helpful for application of the system to complexly-shaped parts. Currently, the completely integrated system is ideally applicable to a family of similar parts, such as bearings, cam rings or gears.
