Forging reduction ratio formula
WebThe reduction or gear ratio is calculated by dividing the number of teeth on the large gear by the number of teeth on the small gear. For example, if an electric motor drives a 13-tooth pinion gear that meshes with a 65-tooth gear, a reduction of 5:1 is achieved (65 / … WebUsing our example it would be ( AfPI*r^2 - AoPI*r^2 ) / AfPI*r^2 = ( 56.74 - 42.55) / 56.74 = 25% Reduction. We then need to make sure that the length of the starting billet will not be too long. A nice general rule is that the volume before forging is the same as volume …

WebAug 3, 2014 · The reduction ratio in each drawing stage was determined as the ratio of the areas of a cross section of a sample before and after plastic deformation. The final (total) forging reduction ratio was evaluated as the product of the ratios obtained in each … WebForging reduction: ratio of the cross-sectional area before and after forging; sometimes refers to percentage reduction in thickness. Forging stock: wrought rod, bar, etc. used as the raw material or stock in forging. Free-machining-steel forgings: those made from steels with special alloying-element additions to facilitate machining.
WebJun 1, 1982 · A re- duction ratio of around 4:1 is necessary with low-alloyed steels in order to be able to achieve good mechanical properties and structure. For plate thickness above 50--70 mm problems with the necessary reduction ratios can be expected. WebReduction can be calculated by r = (D b - D p )/ (D b ). D b and D p being blank and punch diameters respectively. Reduction should be .5 or under. Often expressed as the percent reduction r = (D b - D p )/ (D b) X 100%. In this case the reduction should be 50% or under. Redrawing Sheet Metal
