Analisis Perbandingan Kinerja Mesin CNC 5-Axis Berbasis Kontroler Mach-3 dan Mesin CNC EMCO TU-3 Axis dalam Pemesinan Geometri 3D

Abstract

This study aims to analyze the performance of a 5-axis CNC machine based on a Mach 3 controller as a result of modification of the EMCO TU 3-axis CNC machine. This modification was carried out to increase flexibility, efficiency, and ease in the process of creating G-code which was previously done manually. Testing was carried out by comparing the performance between 5-axis and 3-axis CNC machines based on the parameters of the number of setups, machining time, dimensional accuracy level, and the number of machining failures. The results showed that the 5-axis CNC machine only requires one setup for each design, but has a longer machining time and a higher dimensional failure rate than the 3-axis CNC machine. Conversely, the 3-axis CNC machine requires more setups, but produces higher dimensional accuracy with fewer errors. The factors causing failure mainly come from errors in determining the center point coordinates, limitations in the cutting tool range, and G-code typing errors. Overall, the 5 Axis CNC machine with Mach 3 controller is able to provide flexibility and ease in the machining process, but still requires improvement in terms of the accuracy of parameter and coordinate settings in order to achieve optimal accuracy in the manufacturing process.
