ABSTRACT: This study presents the design and implementation of a mechatronic system aimed at improving the efficiency of machining operations in Computer Numerical Control (CNC) machines. This developed system automatically adjusts the feed rate of the CNC milling machine based on the wear condition of the cutting tools by monitoring their status via sensors during the milling operation. This system, integrating mechanical, computer, and electronic engineering disciplines, adopts an interdisciplinary approach to minimize errors and production losses arising from operators’ lack of experience. Data acquired through a vibration sensor is utilized to optimize machining parameters (cutting speed and feed rate), with the goals of extending tool life, improving the surface quality of the workpiece, and reducing overall production costs. While existing systems in the literature primarily focus on tool condition monitoring, this study proposes a universal solution that can be adapted to various brands and models of CNC machines, capable of adjusting the feed rate automatically without altering the original structure of the machine.
