Experimental study on cutting force of face-turning Inconel718 with ceramic tools and carbide tools

Abstract

In the process of face-turning high-temperature alloy Inconel718 with carbide tools and ceramic tools, the change rules of cutting force were studied and the empirical models of cutting force on the cutting parameters were established. For the tools, the main cutting force has positive relation to both the feed rate and the turning depth. Variation trends of the axial force are in accordance with the increase in these two parameters. During the increasing process of the cutting speed, the feed force changes slightly while the main cutting force decreased about 96 N when using the carbide cutter. For the ceramic cutter, the main cutting force and the axial force increased to about 380 N first and then decreased when the cutting speed increased. The axial force affected not only the processing parameters but also the geometrical parameters of the cutter. There exist some relationships between component forces.
