Simulation and experiment based optimization of calligraphy manufacturing using a 5-axis CNC Milling Machine

The optimal performance of a 5-axis CNC Milling Machine depends on cutting completion time and cutting tool lifetime. Cutting tool lifetime can be measured based on the amount of chips adhering to the cutting tool after milling process completion. These conditions are affected by two parameters: feed rate and the milling depth. To find the optimum parameters, simulation and experiments were conducted using MasterCam X7 CNC Software and a DMG Mori 5-axis CNC Milling Machine, respectively. The material used in this study was Polymer Necuron 651. The study results indicate that higher feed rate and deeper milling caused greater adhesion of chips and reduced cutting tool lifetime. The best parameter obtained was at 0.5 mm milling depth and 300 mm/min. feed rate.
