An attempt to analyze influence of properties of five African wood species on cemented carbide tool wearing

Abstract

In this paper cemented carbide cutting tools dulling after milling five African wood species is presented. Wood specimens investigated varied with the high temperature corrosivity (HTC), the hard mineral contamination (HMC), and the density (D). An attempt to replace combustion method of evaluation of content of natural HMC in wood with spectral mass analysis methods like energy dissipative spectrum (EDAX) or atomic absorption spectrometry (AAS) failed. Experiments performed show that scanning electron microscope (SEM) analysis of ash allowed to get information on size and shape of small dimension natural HMC particles present in wood specimens. Employing theoretical multi variable simulation, the combined effect of the HTC, the HMC, and the D on the cemented carbide tool wear was evidenced, which appeared to be a good explanation of the results observed.
