ABSTRACT
The main goal of the presented research is to assess the technological damageability of the material, which can be used as a criterion for analyzing the technological route of product machining in the "blank-workpiece-final part" technological chain. This technological chain is examined in detail in the most important stages of the life cycles of mechanical engineering products in order to take into account the principles of technological inheritability of their characteristics and quality parameters. The technological inheritability of the properties of the surface layers of machines and mechanisms parts from steel during their machining evaluates and predicts the transformation of the structurally heterogeneous material obtained after the production of blanks into the structurally homogeneous material of the final parts. The procedure for evaluating the homogeneity of the processed material for each technological step by the LM hardness method is presented. The developed methodology was implemented and proven during the manufacturing process of the conveyor belt drive drum shaft.
