The article covers technological processes of crankshaft production using bending opera-
tion. It also describes a procedure of
selection of cross-wedge rolling as a method of
producing a preform
. We used
Qform
program to model the preform wedge rolling pro-
cess
taking into consideration different friction conditions and to check
adequacy of the
formula to determine the friction on the contact surfaces of the tool
.
Keywords:
cross-wedge rolling, hot forging, crankshaft
