Machining of nickel alloy by cutting tool with prepared cutting edge preparation

Popis výsledku v původním jazyce

The article deals with machining and development of the wear of cutting tools for turning of nickel alloy Inconel 718 2.4648. This alloy is characterized by high strength and toughness, low thermal conductivity and high abrasion. As a result of these properties, the alloy has worsened machinability and it is necessary to put emphasis on technology, a choice of cutting tools, their geometry and cutting conditions. The exchangeable cutting inserts marked VBMT 160402F-1, made from sintered carbide and pre-verified cutting conditions were used for machining of the alloy. A microgeometry of cutting tools was defined with brushing technology and abrasive jet machining technology. The edge radius rn = 20+-5 μm on cutting inserts was created by the brusher with abrasive corundum particles and the edge radius rn = 20+-5 and 35+-5 μm was created by abrasive jet machining technology. A gradual wear development and its intensity was checked during turning process of Inconel 718 with the use cutting tools with rectified cutting edge. Depending on intensity of a wear on major flank was determined a tool-life of cutting inserts and an influence of the microgeometry on machining process of alloy was considered.
