  4. Abstract:
  5. Surface integrity is one of the important parameters affecting the quality and functionality of mechanical components. This paper presents an investigation on effect of drilling parameter on the surface integrity of Inconel 718 through a combination of experimental and simulation works. The machining responses that are determined through the experimental work include microhardness, microstructure changes, and surface roughness. The average grain size of the microstructure of the workpiece is estimated by using a simulation model. The experimental and simulation results show that higher spindle speed facilitates the formation of white layer near the machined surface and decreases the average grain size. Furthermore, it is observed that the surface finish deteriorates with an increase in feed rate. © 2021, The Author(s), under exclusive licence to Springer-Verlag London Ltd., part of Springer Nature
