摘要
The paper presents the results of a comparative analysis of dynamic stability of SiC whisker reinforced alumina tools used in a conventional and prototype toolholders when turning a nickel-based superalloy Inconel 718. The use of the prototype toolholder with a cellular spatial structure is shown to significantly suppress vibrations during the machining operation and stabilize the cutting process within the cutting speed range between 200 and 500 m/min. Considering the identical nature of tool wear rate and the analytical ellaborations regarding the process dynamics, the above-mentioned benefits are related to damping properties of the proposed toolholder.
