Study on Tool Wear in Green Milling Ni-Based Superalloy

Abstract:

In order to solve the difficult machining problem of Ni-based superalloy, the water vapor and ionized air was applied as coolant and lubricant in milling process. The tool wear experiments on water vapor, ionized air, wet and dry cutting with carbide tool YG6A machining Ni-based superalloy GH4169 was carried out. The result showed that tool wear was quickly on milling GH4169 with carbide tool YG6A, and increased with the cutting speed.The flank wear land was uneven and the boundary wear was serious. During the ionized air condition the flank wear was more slowly than wet and dry cutting condition, the values of flank wear were reduced about 15 and 10 percent respectively. In addition, the result showed that The milling force and machined surface roughness increased with the flank wear.
