A computer program in FORTRAN language was developed for calculating geometrical parameters for axisymmetric forgings. Using the dimensions and the angles given in the engineering drawing of the forging, the program calculates the forging volume and weight. The shape-difficulty factor may prove useful in process design, for cost estimating, and for assisting engineers to make decisions about feasibility and difficulty in manufacturing. Empirical equations suggested by German and Soviet workers are used for calculating the flash dimensions and the flash weight. The computer program is applied to various forgings, and theoretical results are found to agree with actual experimental data. The developed computer program is now available to interested forging companies. It could be used for a systematic analysis of existing forging data, for making cost estimates after incorporating in-house cost factors, or for designing axisymmetric forgings with minimum additional effort.
