“…Several studies have been carried out in order to first understand the different mechanisms contributing to cutting edge wear of tungsten carbide tools during MDF machining [1,2], second to improve tool life using hard coatings [3,4], cryogenic treatment [5] or different kinds of tungsten carbide [6]. Nevertheless, no study has been conducted to define the machining ability of different types of MDF.…”

is an open access repository that collects the work of Arts et Métiers ParisTech researchers and makes it freely available over the web where possible. a b s t r a c tNowadays, medium density fibreboard (MDF) composite wood is more and more used in the furniture industry to replace bulk wood such as oak, beech, etc. Indeed, this material presents good mechanical properties, is easy to machine, homogeneous, exists in different dimensions (thickness, etc.), is cheaper than bulk wood and finally can be covered by an adhesive decorative coat. Nevertheless, even if this material is homogeneous, it is abrasive enough to tend to the breakdown of the conventional carbide tools employed during its routing process. That is why it is necessary to improve the wear resistance of these tools. One solution is to protect them with a hard coating.The present study deals with the development of ternary CrAlN hard layers obtained by PVD method on carbide tools employed in second transformation of wood. CrAlN coatings have been optimized and then applied on carbide tools in routing of three types of MDF: standard, waterproof and fireproof. The aim of these wood machining tests was first to define the ability to be machined of the three kinds of MDF and second to compare the effectiveness of CrAlN coatings during the routing tests of these materials.

“…The high noise levels generated during high-speed cutting are probably caused by large impact force being imposed on the tools for the high-speed cutting. It is also observed from the results in Figure 6 that though the amount of clearance wear of the TiN/AlN coated carbide was much lower than the other tools investigated [5], however its noise level is almost the same as that of the other tools. This could be due to the extreme hardness of the TiN/AlN coated tool, which imposed large impact during the cutting.…”

“…Experimental results in Figure 5 show that the TiN/AlN coated carbide tool generated the smallest parallel force for all cutting speeds at the final cutting length among the tools investigated. This is considered to be due to the fact that the TiN/ AlN coated carbide tool suffered much lower amount of clearance wear at every cutting speed performed compared to the other tools investigated [5]. On the other hand the other tools investigated varied slightly in the parallel force as the cutting speed was increased.…”

“…For this discussion, relation between parallel force and cutting speed for the final cutting length is provided in Figure 5. The increase in the parallel force with an increase in cutting speed was caused by larger relaxation of the work material on the clearance face [2] and greater amount of clearance wear [5], which further caused high rubbing pressure on the clearance surface of the coated carbide tools, being attained by the cutting tools for the high cutting speed. Experimental results in Figure 5 show that the TiN/AlN coated carbide tool generated the smallest parallel force for all cutting speeds at the final cutting length among the tools investigated.…”

-Coated carbide tools were tested for turning of wood-chip cement board. Coating materials, which were synthesized on the P30 carbide substrate, are titanium carbonitride, titanium nitride, chromium nitride, and titanium nitride/aluminum nitride. Cutting tests were performed at cutting speeds of 30, 40, 50 and 60 m/s, depth of cut of 1 mm, and feed of 0.05 mm/rev. Wear, parallel force and noise level were measured at every specified cutting length. The purpose was to discriminate various stages of wear of the coated carbide tools by the features extracted from parallel force and noise level. The results of the study show that both the parallel force and noise level generated by the tools tested were observed to increase linearly with increasing the tools wear, and would be good parameters for monitoring the tool wear. The parallel force and the noise level of the cutting tools also increased with increasing the cutting speeds for every specified cutting length. The parallel force became more sensitive than the noise level for monitoring the tool wear when the cutting speed was increased.
