Monitoramento da Vibração Durante o Processo de Torneamento de Ligas de Aço de Baixo Carbono

Abstract

The machining process is characterized in the part manufacturing where the removal of material occurs in the form of chips, being of fundamental importance for metalworking industries because it facilitates in some of its production stages. Among them, there is turning, commonly used to manufacture cylindrical parts such as axles, cylinder heads, engine block machining, valve controls and crankshafts. The quality of the machining is directly related to the surface finish of the part, which can be measured using the parameter of the analysis of the vibrations that occur during a normal turning process. High levels of vibration can lead equipment to fatigue, and consequent breakdown, which can cause production losses, service material supply problems. The objective of this work is to monitor the vibrational movements during the turning of low carbon alloys. For such analyzes, two sensors were used for data acquisition, the Arduino, which has a low cost and the piezoelectric sensor, which is more expensive but more accurate in its data acquisitions. Several tests are carried out so that the Arduino board can collect sufficiently reliable data, but it is shown throughout the process that it is unable to generate the necessary data, thus requiring a board with better quality.
