OPTIMIZATION OF CNC MILLING MACHINING PARAMETERS ON PROCESSING TIME AND SURFACE QUALITY USING NANJING SWANSOFT SIMULATION

Abstract

Time efficiency and surface quality are two key factors that determine the success of a production process in the modern manufacturing world. This study aims to optimize CNC milling machining parameters for processing time and surface quality by utilizing simulations using the Nanjing Swansoft application. The parameters analyzed include spindle speed, feed rate, and depth of cut. The simulation was performed using an aluminum workpiece and a flat end mill with a diameter of 10 mm. The simulation results show that the combination of spindle speed 1500 RPM, feed rate 300 mm/min, and depth of cut 1 mm produces a stable, efficient machining process and produces a good surface finish without cutting errors. The obtained cutting speed of 47.12 m/min is considered suitable for aluminum material. The use of the Swansoft application has proven effective as a learning medium and virtual testing of machining parameters without the risk of tool damage or high costs. Thus, this digital simulation can be a practical solution in CNC training, especially for students and novice operators, and provides a strong foundation before the machining process is carried out directly on a real machine.
