Evaluación de los parámetros de mecanizado basados en el análisis del espectro de vibraciones para el proceso de torneado del acero ASTM-A36 : evaluación de operaciones de cilindrado sin lubricación.

Abstract

This Project aims to evaluate the cutting parameters’ impact on the system’s vibration while the low carbon steel specimens are being turned. To get this information, several techniques are used, the principal technique is the measurement and analysis of the vibration spectrum generated during the turning process. Also, an analysis of the roughness test and the virtues generated in the process is carried out. It begins with a bibliographic review about the cutting conditions on the system vibration. After, the experiment’s design is based on fractional factorial method which allows to reduce the treatments quantity and it’s planned to repeat the procedure three times for statical analysis. Besides, because of kind of fasting in conventional lathe, it is proposed to have two specimens with two different lengths. The results obtained from the vibration spectrum are processed, then an evaluation of the turned surface is carried out using the roughness test and the chips generated during the process are contrasted. Finally, feed rate, cutting speed and depth are the parameters that determine the vibrational responses during turning. So, as the parameters get raised, greater disturbance is also generated in the system, and it could be check in the roughness profile and vibration measurements.
