Mathematical Model and Program Development for the Efficient Process Conditions Determination during FeC0.15Cr12Ni2 Steel Diamond Smoothing

Abstract

In this paper the mathematical model and the program based on this model for efficient process conditions during a diamond smoothing is introduced. The mathematical model has been tested with heatproof martensite category steel FeC0.15Cr12Ni2 by the synthetic diamond DSB-1 using as a smoothing tool. The mathematical model takes into account plastic deformation degree which could have both smoothing and reinforcing nature. Through the smoothing conditions the surface has a microroughnesses crumpling but reinforcing conditions involve also surface layer microhardness increasing.

Investigation of Conditions of Processing Influence on Micro-Hardness Distribution in Surface Layer during Diamond Burnishing of Samples of FeC0.15Cr12Ni2 Steel

“…That is, the determination of these parameters, as observed in work [3], is needed for reliable estimation of the operating characteristics of the details of aeronautical engineering and of products in whole. It should be noted that empirical dependences, connecting micro-hardness and depth of workhardening of surface layer with parameters of diamond burnishing process, can be used as technical restrictions in mathematical models for determination of rational conditions of processing during diamond burnishing [4].…”
