Reliability Assessment in Mechanical Wear of Deforming Rollers on the Combinedtools for Cutting and Surface Plastic Deformation

Nikolay Petrov, Ventcislav Dimitrov, Panayot Chobanov

Abstract :

In this work is proposed a methodology for assessing the reliability indicatorpreservabilityin mechanical wear of deforming elements of combined tools for cutting and surface plastic deformation (SPD) by evaluating the quantitative parameter – intensity of wear. Sampled value reflect important processes accompanying plastic deformation characterizing wear such as friction fatigue deformation of micro roughness, thermo–dynamic processes operating at non– deterministic modes with and without application of the luicant cooling liquid (LCL) and others.
