Machinability investigation on nickel based super alloys using textured inserts

Machinability investigation on nickel-based super alloy under the influence of textured tungsten carbide inserts is performed in this current study. Machinability indicators such as surface roughness and tool wear have been investigated. Similarly, texture patterns such as dots, circle chain and zig zag shaped textures have been fabricated on CNMG120408 WC inserts using Laser source. The primary objective of the present investigation is to compare the performance of different types of tools when they are used with different parameters such as cutting speed, feed rate, and depth of cut. It has been observed that the surface roughness and tool wear of the dot shaped textured tool were lower when compared to the other types of tools. Dot shaped textured inserts and circle chain shaped textured tool was able to perform better than the other tool inserts.
