520			_aThe 3-axis milling machine is important to modern society, offering precision, efficiency, and versatility that significantly enhance manufacturing, prototyping, and creative industries, thereby fostering innovation, increasing productivity. The study achieved to develop a small-scale three-axis CNC milling machine. In designing the machine, the researchers used Palm Router, Arduino Uno, NEMA Stepper motor, and Aluminum Profile Extrusion in different sizes. To test the machining capabilities of the machine across different materials namely: wood and acrylic, the researchers conducted the circular test and flatness test. The researchers evaluated the machine's accuracy and repeatability by conducting positional testing using dial gauge readings across multiple repetitions. The performance capabilities of the CNC machine were further assessed through circular test conducted at three different spindle speeds and feed rates. While the flatness test is conducted with a predetermined feed rate of 2540 mm/min and spindle speed of 17200 RPM. The CNC milling machine exhibits high precision in positional accuracy, excellent circularity, and reliable flatness, making it a reliable tool for precision machining in various manufacturing applications. The findings and methodologies detailed in this study offer valuable insights for further advancements in compact CNC technology, paving the way for enhanced productivity and innovation in various industries, including education, prototyping, and small-scale production.
