Analysis of Forging Processes for Machine Building Industry Modeling

Abstract

This paper presents the efforts of forging process. As new uses for various metals multiplied, and the superior quantities imported to metals by forging came to be more positively recognized, the forging industry accelerated its efforts to produce more and better products at diminishing cost. During the production of a crankshaft weighing 17 kilograms from a bar of rolled steel, up to 31.5 kilograms are irretrievably lost as chips in machining. When the same weight of crankshaft is manufactured by the forging process, only 13.7 kilograms of steel are lost in chips. i.e. the loss is 56.6 percent less. When the temperatures increase, it is found that forging load decreases. Forging load is directly proportional to the percentage of reduction. Low carbon steels are easy to forge and super alloys are difficult to forge .In this paper, three different types of materials namely, 1020 carton steel (crankshaft), A-286 alloy (turbine disc) and 6061 alloy (aircraft housing) are analyzed to determine the relationship between the forging temperature, forging loads and percentages of reduction. There were made at the laboratory, Department of Metallurgical Engineering and Materials Science, Yangon Technological University.
