COMMENTS
The weak correlation enters the average effort and the studied factors: average thickness of the
chip and density (figures 3, 4, 5) is due to the preponderance of the heterogeneity of the panels
compared to the constitution and density of the panels : the size of cut particles and their
involuntary separation resulting from the vibrations during the transport of the cake during the
composition of the panel.
The profile of density not being symetrical on all the thickness of the panel involves during the
machining variable cutting pressures, which explains the weak correlations resulting from the
study. The influence of the effort compared to the average thickness of the chip is due to the
weak range depths of cut used. This is why, it would be interesting for the rest of this work to
extend the values by taking different cuts in order to better explain these parameters. As for the
power, we will say that the force and the power of the tool during the work of removal of the chip
are obviouly correlated. The variations of the results are explained by the vibrations produced at
the time of the hold of the chip to which are added those generated by the mechanisms of the
machine (figure 2) and the heterogeneity of material.
