The purpose of this paper is to discuss how to improve the automation of lathe machines. Modern technology, which utilizes computer software, hardware, and firmware in industries, can now produce products. It is necessary to employ a CNC or semi-automated control lathe machine to increase the pace at which parts are produced while maintaining the same quality for all work parts while improving dimensional accuracy, resulting in precise and correct dimensions. As a result, in modernized industrialization, these machines are becoming increasingly vital. Retrofitting these traditional lathe machines into semi-automatic control lathe machines is required to build a new modern developed country. There are three components required for developing and changing into a semi-automatic control lathe machine, namely mechanical electronics and hydraulics. In this project, we add additional plates or a structure for motor installation. Remove any unneeded components, such as gears, from the mechanical side to provide room for motors. On the electronic side, we employed a stepper motor for both the Z and X axes, as well as a controller to ensure smooth operation.
