Advanced Tool Materials and their Influence on the Parameters of CNC Machining of Wood-Based Materials (Part III)

Abstract

This study investigates the effects of tool coatings, cutting speed, and feed per tooth on cutting forces during CNC milling of Medium Density Fiberboard (MDF). CNC milling parameters, specifically cutting speed and feed per tooth, significantly impact tool wear, energy consumption, and surface quality. Coatings can enhance tool performance by reducing friction and heat transfer, thus potentially lowering cutting forces. However, there is limited research on how coatings affect MDF machining. This study examines five coatings, including DLC, TripleSi, Hyperlox, and a lapped surface, to identify optimal combinations for improved machining efficiency. The objective of this research is to systematically evaluate the effects of different tool coatings, cutting speeds, and feed per tooth values on cutting forces during CNC milling of MDF.
