Abstract

Nowadays, a monitoring technology has attracted attention in the factory automation fields regarding IoT (Internet of Things). However, it is difficult to monitor the process information from a round tool during rotating operation in machine tools. We therefore have developed a novel tool holder equipped with a wireless communication function to monitor a cutting process. In the present report, we also attempt to develop a wireless compact acceleration sensor to monitor the cutting process in various kinds of machine tools. We set a developed sensor around the cutting tool in a lathe and perform to estimate a plunge cutting processes with measuring the cutting force and the acceleration vibration. As a result, we demonstrated that the developed method with a wireless system is effective to evaluate the wear and the flake damage of cutting tool under tuning processes.
