Research on the influence of cutting rates on macrogeometry deflections of surfaces under processing complex form products made of aluminium aloys /

The article reviews the influence of cutting rates on macrogeometry deflection of milling complex form products and turning an outside surface. For that purpose, one of the most popular aluminium alloys 6082 has been chosen. A ball nose mill of 8 mm in diameter has been milled employing CNC vertica...
