The paper presents a new, multi-criteria method which allows the numerical evaluation of the machining process in terms of efficiency, quality and costs. Three indicators were developed to assess the operational properties of grinding wheels. Their values are determined on the basis of the results of short grinding tests carried out on a special test stand. The evaluation of the proposed indicators...
In the paper author described results of geometric structure identification of grinding wheel cutting surface (GWCS) for different wheel characteristics. Dressing parameters and several grinding processes were analyzed. For evaluation of GWCS micro-geometry and analysis of normal distribution of profiles, achieved from surface analyzer, was applied. The results of the analysis are also under discussion...
W niniejszej pracy przedstawiono system oceny użytkowych właściwości ściernic. Stosowane dotychczas metody oceny wykorzystują empiryczne modelowanie matematyczne w postaci funkcji potęgowych. Są one niewystarczające z uwagi na wprowadzanie wielu uproszczeń, które powodują powstawanie znaczących błędów prognozowania wyników procesu. Użytkowe właściwości ściernic często ocenia się pośrednio przez śledzenie...
In the paper an analysis of grinding process simulation results is described. The analysis was carried out on the basis of grinding wheel cutting surface (GWCS) profile measurement. In the next step, a neural model was used to evaluate a relationship between parameters, characterising potential functional properties of GWCS and real grinding results, described by residual stresses and roughness of...
In the paper the results of analysis of grinding wheel cutting surface (GWCS) during dressing operation are shown. A concept of GWCS state evaluation, based on statistical parameters concerning static cutting edges lay-out was proposed. Using GWCS topography measurement data-base, a neural model of GWCS topography was presented. The model employed grinding wheel characteristics and dressing conditions...
