Wear Behavior of Uncoated and Coated Tools in Milling Operations of AMPCO (Cu-Be) Alloy

Copper-Beryllium alloys have excellent wear resistance and high mechanical properties, they also possess good electrical thermal conductivity, making these very popular in a wide variety of industries, such as aerospace, the fabrication tools for hazardous environments to produce injection molds mold inserts. However, there are some problems processing alloys, particularly when subject machining processes, causing deteriorate quite rapidly, due material adhesion tool’s surface, caused by material’s ductile nature. An assessment tool-wear after Cu-Be alloy AMPCOLOY 83 using coated uncoated was performed, offering comparison performance behavior solid-carbide DLC/CrN multilayered end-mills with same geometry. Multiple tests were conducted, varying values feed cutting length. In initial tests, force registered. The surface roughness evaluated tools’ edges subsequently analyzed, identifying main mechanisms how developed during machining. exhibited better shorter lengths, producing lower degree on machined material. registered less intense than that tools, which suffered more adhesive abrasive damage. it observed that, greater tool performed terms sustained wear.
