Roughing Milling with Ceramic Tools in Comparison with Sintered Carbide on Nickel-Based Alloys

Productivity in the manufacture of aircrafts components, especially engine must increase along with more sustainable conditions. Regarding machining, a solution is proposed to cutting speed, but engines are made very difficult-to-cut alloys. In this work, comparison between two tool materials, namely (a) cemented carbide and (b) SiAlON ceramics, for milling rough operations Inconel® 718 aged condition was carried out. Furthermore, both influence coatings tools speed ceramic were analysed. All tested until end their useful life. The cost performance ratio used compare productivity tools. Despite results showing higher durability coated tool, presented better behavior terms at speed. Therefore, should be demands, while low speed-high volume material removal.
