Test Methodology to Relate Machined Surface Roughness and Acceleration

Abstract

This paper aims to establish a direct relationship between the value of the acceleration and the roughness profile. To this end, a system of testing has been designed to link the value of the acceleration to the position of the tool on the surface of the piece at each time step. In order to allow a more detailed monitoring, rather than measuring a generatrix of the piece, readings are taken on a machined surface which is comprised of widths, between 7 and 10 mm, and lengths, between 20 and 100 mm, where segments of the helical path of the tool on the piece are observed, thereby linking the path to specific values of the readings by the accelerometer.
