Development of Three-Axis Mini Milling Machine for Small Scale Production

Abstract:

This paper presents the processes to develop a cost-effective small scale 3-axis CNC milling machine. The designed machine tool consisted of stepper motors, bearing, linear guide, ball screw mounting systems, inverter and electronic controller, in which all of these are assembled together in a form of 3-axis operating system. The machine has a built up with the size of 1000 mm (length) × 1000 mm (width) × 650 mm (long) accompanied with a worktable with a dimension of 300 mm (length) × 300 mm (width) × 20 mm (long), and 24,000 rpm maximum spindle speed. To control the movement of the machine, open source software was utilized with the aid of G-Codes to assign the movement of the CNC axes. From the machining test, the machine was found to be capable to machine a metal work piece with high cutting speed and reasonable accuracy. The machine developed in this study offers efficiency and flexibility in the manufacturing production which enables to reduce capital cost due to the small-scale facility.
