Abstract
This paper aims to analyze the vibration of the boring process using a tool holder with a length / diameter ratio high. Tools with great length on the balance sheet are likely to occur regenerative vibrations during machining, damaging the process and generating an undesired surface roughness. Tests performed to obtain data will be performed using measurement equipment such as microphones and loading platforms. The proposal will be to analyze the influences of machining parameters such as speed, depth of cut and advance in the vibrations of the boring process through the use of data generated for the determination of process stability chart while the simulations in MatLab software using a mathematical model more complete and pre-set. It was observed that the pre-tests during the unstable process, vibration occurs in the natural frequency of the system. For the analysis of data collected by the microphone is used a signal acquisition board, a microcomputer and a program for analysis, ITAtoolbox. The material used for the experiments will be aluminum 6351-T6, and will be used three types of toolholder allowing a series of assemblies for the experiments. At the end of the experimental results will be compared with the numerical simulation values.
