Abstract
The frictional resistance plays a key role in sheet metal forming processes, especially in automotive and aerospace industry. The AMS5599 nickel-based alloy is hard to form heat and corrosion resistance material, and requires special forming conditions. In this paper, frictional resistances of 1-mm-thick AMS5599 alloy sheets were evaluated using a simulator of strip drawing test. The tests were conducted at dry friction conditions and under lubrication of machine oil and chlorinated honey-type stamping oil. The nominal contact area of the specimens with countersamples has been determined numerically using the finite element-based MSC.Marc program. The results of experiments show that the friction coefficient decreases with an increase of nominal pressure. The sheets tested exhibit high strengthening phenomenon that limits an increase of contact area under normal load.
