Increased demand of energy efficiency for the components used in aerospace and energy industries requires high efficiency and low cost in the production of component made of nickel-based superalloy, such as aged Inconel 718. With use of whisker reinforced ceramic cutting tool in finishing machining process, higher cutting speed and higher production(More)
Subsurface microstructural alterations and residual stresses caused by machining significantly affect component lifetime and performance by influencing fatigue, creep, and stress corrosion cracking resistance. Assessing the surface quality of a machined part by characterizing subsurface microstructural alterations and residual stresses is essential for(More)
Results of the study of cutting speed and tool wear influence on the vibrations and their nature during machining superalloy Inconel 718 with low cBN content (cBN-L) and binderless pcBN (bcBN) tools are presented. Cutting speed was varied from 2 to 14 m/sec while other cutting conditions were constant. The process evolution was studied with the wavelet(More)
