Experimental Investigation on Machine Tool Vibration during Machining of En-31 Carbon Steel Material

Abstract

Milling is a widely used machining process for creating intricate parts with desired dimensions and surface quality. In this study, we investigate the effects of process parameters namely spindle speed, feed rate and depth of cut on the vibration behavior of a milling machine tool. The analysis begins by selecting appropriate cutting conditions for the milling operation. Various combinations of process parameters are considered to observe their influence on vibration of the tool. A series of experiments are conducted, with each experiment using a specific set of process parameters. The experimental trials were designed according to the factorial design. Accelerometer is employed to capture the dynamic behavior of the tool and quantify the amplitude and frequency of vibrations. The results can be utilized to optimize the machining parameters for enhanced surface quality in milling operations, leading to improved productivity, reduced tool wear and increased overall process efficiency.
