Type and Size Filler Grain Selection During Abrasive Flow Machining of Non-Ferrous Alloys Rectangular Parts

Abrasive flow machining is one of the promising technologies for finishing rectangular channels, which are characterized by a constant increase in accuracy and reduction surface roughness. During modeling contact interaction grains corners part cross-section intended abrasive machining, key features size filler grain selection were fixed. In proposed spherical model, cutting edge represented an arc circle that fits into angle part. It confirmed if exceeds value inner radius rounded corner part, untreated zone appears, with area calculated using CAD system on straight, blunt sharp angle. proved not exceeding doubled rounding cross section carried out. The physical properties, shape edges applicability fillers, electrolytically produced corundum, silicon carbide synthetic diamond analyzed. grain, comparison fillers mentioned above, shows more crystal faces, causes greater microhardness ability. revealed confirm exclusion possible phenomenon, caricature process post-processing. recommended to use certain uniform pretreatment rough surface, followed polishing ointment-like paste channels small transverse cross-section. Using as salve-like containing allows reduce medium viscosity section. heat-resistant rubber base used non-ferrous parts. working media pastes will allow internal blanks made various alloys be treated flow. For minimum sections pipe presented this article, it following weight composition: - 40 %, ASN 60/40 PTO 60 %. A number general recommendations further research.
