“…Approximation was made with linear and quadratic regressions. In similar mechanical processes, Cortadi et al [46] showed that quadratic approximation was the one that fit best. Nevertheless, in this particular machining process, the second order curve introduced some physical incoherence in some of the series, and the first order approximation gave better results.…”

This paper presents the process required to implement a data driven Predictive Maintenance (PdM) not only in the machine decision making, but also in data acquisition and processing. A short review of the different approaches and techniques in maintenance is given. The main contribution of this paper is a solution for the predictive maintenance problem in a real machining process. Several steps are needed to reach the solution, which are carefully explained. The obtained results show that the Preventive Maintenance (PM), which was carried out in a real machining process, could be changed into a PdM approach. A decision making application was developed to provide a visual analysis of the Remaining Useful Life (RUL) of the machining tool. This work is a proof of concept of the methodology presented in one process, but replicable for most of the process for serial productions of pieces.
