The Effect of Manufacturing on the Press fit Insertion Force

摘要

In the automotive industry and not only, it is useful to have a very fast and simple assembly process between parts, so it is used the press fit process between parts. Usually, the press fit force depends on part geometry, radial interference between parts and material behavior. In this study was used one shaft (only one dimension) and thin sheet metal with different size of hole in order to have more interference values between parts. This work will present a comparison of the press fit force between the two types of manufacturing process (machining and blanking) of the hole in sheet metal. The numerical analysis is calibrated with the experimental measurement for machined hole in sheet metal.
