Abstract:

This work concerns burnishing rolling the shafts with elastic pressing of burnishing elements. One of the most important problems during designing this process is calculate value of technological parameters: principal force of burnishing (F3), feed (fn) and velocity (vn). The principal force of burnishing was calculated by integration the elementary contact pressure over contact zone. It is possible to determinate as product of means the contact pressures and contact zone. It requires to determinate the both distributions it contact pressures and calculate of mean value and contact zone. The unacquaintance of the contact zone or contact pressures distributions leads to incorrect calculations of principal burnishing force and this can bring to destruction of work-pieces surface layer. In this work the numerical way of contact zone determinate between burnishing elements and work pieces was shown. The cases with the option when the roughness of surface after previous process were analyzed.
