Analysis and prediction of cutting force through lathe tool dynamometer in CNC turning process

Abstract The cutting force measurement in the machining process is a complicated one for precise measurement. All types of machining process the tool and wok piece interaction create some vibration it causes the tool failure. For the avert of tool wear or failure based on the estimation of cutting force, the cutting force may not be directly measured with human sensing. This investigation intense to measure and predict the cutting force in CNC turning process by using of lathe tool dynamometer with load cell based and piezoelectric sensor based dynamometer, which one is produce accurate result. Apply of these two dynamometers the cutting forces are measured and analyzed with influence of turning process factors. The Taguchi route is execute to analyze the cutting force, the process variables are chuck speed (rpm), feed (mm/rev) and cutting depth (mm). The ANOVA analyze are illustrates the contribution percentage of the each process variables accurately. The measured values through dynamometers and predicted values are accurately obtained.
