This master thesis shows the development, testing and study of a system that enables pulsating high pressure assisted turning. Overview and comparison with classic turning and high pressure assisted turning is done. That is the basis on which the mentioned system was developed and compared with the intention of improving/eliminating other systems shortcomings.
Properties of nickel and titanium based alloys that make them desirable engineering materials are the same properties that define them as hard-to-cut materials. High temperature in the cutting zone causes high stress and load on the cutting tool and effectively lowers tool life. One of such materials is Inconel 718, which has low thermal conductivity, high corrosion resistance, shows deformation hardening, etc.
The purpose of the conducted experiments was determining the effect of pulsating high pressure assisted machining on the process of turning with focus on control of chip formation, cutting forces during machining, energy consumption of the system and tool wear.
It was found that pulsating high pressure turning has a lot of potential as it shows greater control over chip formation and breakability, requires less energy for turning compared to high pressure turning and lowers the cutting forces compared to classic turning. Tool wear is worse when compared to high pressure turning but better compared to classic turning.
