The manufacturing industries have been proven to lead to the increase of gross domestic product, an indicator of economic growth. As one of the most contributing factors in the industry, machine tools make a significant investment. Improvement of machine tools' ability could directly increase productivity in the manufacturing industry sector. Manufacturing industry sector is developing automation as the feature of machine tools. There are milestones to fulfilled before the machine would be completely automatic, the first one being the monitoring process. Monitoring activity allows each production element to know the conditions during the process of production. The electric consumption and the duration of the process have a big impact on the overall production. Using the value of power consumption, the manufacturer can determine the effectivity and capability of the machine. Combined with other information, data obtained can be helpful for the manufacturer to make decisions regarding the production processes. This final project is focused on getting the information of process duration and electric consumption on conventional machine tools, with the study case on Harrison M300 Lathe Machine. The data are obtained by monitoring live line that connects the machine tools to the electricity source. The devices used for designing energy consumption monitoring modules are Wemos D1 Mini, power supply, and YHDC model SCT-013 current sensor. The testing of the device has been done on the M300 Harrison Lathe Machine. The results of the testing prove that the system can do its function to monitor the electric current flowing to the machine, to store the data into a designated database and to show the data using the designed interface.
