The manufacturing industry is a viable source of economic growth in the world, more so in Indonesia where the manufacturing sector is highly focused. Machine tools, as one of the most valuable assets in manufacturing, should be developed to make manufacturing processes more efficient. In the current era of Industry 4.0, the development in mind is the addition of a cognitive function, one that may make machine tools smart by integrating it with the network and database. Smart machine tools may, in the future, be efficient in scheduling maintenance and so forth. The simplest form of cognitive function is the machine may know what it is going through by creating a “cyber twin” through monitoring systems that identify process parameters. Acquired data will then be uploaded to a database where the data can be stored for future use in order to optimize the overall manufacturing productivity and be interactable with a user. This thesis focuses on adapting an existing machine tool, a TPM D018S Drilling Machine, by acquiring the data of current and rotational speed in order to define which usage phase the machine is going through, dubbed machine phases. The machine phases are defined by simultaneously acquiring both data and set a certain threshold so that the system can differentiate the phases, in this case are Power On, Noncutting, and Cutting phase. The system designed has been successful in monitoring multiple parameters simultaneously and in defining the phase threshold. The Cutting phase thresholds are above 8.63 amperes and below 1440 rpm.
