RANCANG RANGUN MESIN MILLING CNC SEDERHANA

Abstract

The development of the manufacturing industry in the 4.0 era drives the need for functional CNC machines. This final project aims to design and build a simple yet precise CNC milling machine that can be used for cutting processes. The main components include a frame made of aluminum profiles, spindles, stepper motors, TB6560 drivers, and microcontrollers. Assembly is carried out in stages, starting from the mechanical system to the machine control system. The machine is tested through function tests and precision tests, including measuring parallelism, perpendicularity, and precision of the X, Y, and Z axes. Precision testing is carried out using a dial indicator with an accuracy of 0.01 mm. The test results show that the machine is capable of producing X, Y, and Z axis movements. Functional testing shows that all main components such as stepper motors, spindles, and control systems can operate according to their functions and preventive maintenance is carried out on main components such as linear guide rails, couplings, and lead screws to maintain the long-term performance of the machine.
