Milling Performance of Fluorinated Surfactants-Based Coating Tools in Processing Particleboard

Abstract

To investigate the cutting performance of tools with fluorinated surfactant-based coatings, the milling performance of melamine-coated particleboard was characterized by means of the cutting force, tool wear and surface quality. A scanning electron microscope (SEM) and a three-dimensional super field microscope were used to observe the morphologies of coated and uncoated tool wear and machined surfaces. The results showed that (1) the surface wettability of the coated tool is lower than that of the uncoated tool; (2) the main wear mechanisms for tools with a fluorinated surfactant-based coating are abrasive wear and microchipping. The fluorinated surfactant-based coating acts as a solid lubricant, which can obviously reduce adhesion wear; (3) the surface roughness obtained by machining using coated tools is much smaller than that found for uncoated tools.
