METHOD OF DETERMINING FRICTION COEFFICIENT BETWEEN TOOL AND BLANK Russian patent published in 2005 - IPC

Abstract RU 2251680 C2

FIELD: plastic metal working.

SUBSTANCE: method comprises calculating the stress-strain condition of the tool and blank with regard for their materials and geometry, plotting a diagram "deformation force - friction coefficient" of the process of plastic deformation, determining experimentally the deformation force, which corresponds to the actual condition of the surfaces of tool, blank, and lubricant, and determining friction coefficient from the diagram.

EFFECT: enhanced accuracy and reduced labor consumption for determining.
