Abstract
For selection and design of the correct size of shears, it is essential to know the values of shearing force and shearing energy and the cutting speed. Accurate values of shearing force and energy can only be obtained from the actual force-penetration characterstics for specific shearing applications. Actual force-penetration characteristics for all varieties of metal having different compositions and in use at various temperatures are not always available. In this paper, methods have been proposed for calculating approximate values of shearing force and energy for cutting different shapes with inclined knife profiles. Formulae to calculate shearing force and energy are derived from mathematical models with certain assumed deviations from the actual cutting process. Published experimental data for specific applications are included for discussion.
