Abstract
AbstractThe essential properties of sintered powder materials are porosity and hardness. It is established that a part made through powder metallurgy methods is exposed to external factors during the finishing stages. It leads to changes in the surface layer’s characteristics of the part. The experimental research program provided definitions of the influence of transverse feed, cutting speed, and porosity on the hardness of a surface layer and its consolidation. The optimal modes of grinding porous workpieces acquired by isostatic pressing of powder materials with further sintering were obtained. Their surface layers are compacted mainly due to the grinding of porous workpieces. The treatment of porous iron parts by grinding increases the microhardness of the surface layer, yet increasing the transverse feed reduces it. Also, it was found that increasing the hardness of the surface layer of the porous workpiece after grinding is possible because of additional movements of the tool without transverse feed.KeywordsIsostatic pressingSintered powder materialPorosityCutting modesMicrohardnessSurface characteristicsProcessing qualityManufacturing innovationProcess innovation
