Experimental Study of Cutting Force and Temperature in the Machining Process of Waspaloy
Waspaloy is a type of nickel-based superalloy that is mainly used in aircraft turbine parts, compressor disks, shafts, and turbine parts. Waspaloy, like many nickel-base superalloys, is difficult to a machine at room temperature (conventional machining). In this paperwork, the cutting force and temperature created in the cutting area of the workpiece by changing different cutting parameters: cutting speed, feed rate, and constant depth of cut, in the dry oblique turning process of Waspaloy investigated. The hardness of the tested workpiece was 382±3 Vickers. In order to investigate the cutting force and the temperature of the cutting area, a full factorial experiment design without repetition was used, and a regression model of the influencing factors was presented to estimate the cutting force. Specifically, by an increase in the feed rate from 14 to 42 (mm/min), the most cutting force change occurred when the cutting speed was 1200 (rpm) and the depth of cut was 0.3 (mm). Moreover, except in test 6, the machining temperature increased with the rise of cutting speed and feed rate in all experiments.
