The Influence of Cutting Speed on Concordant and Discordant Tangential Milling of MDF

The tangential milling is consistent when the direction of forward movement is equivalent to the movement of the cutter. But the dissenting milling is when the sense of forward movement is contrary to movement of the cutter. The way the material is removed differentiates and may cause different results in apereza the surface. For Medium Density Fiberboard ? MDF material and which is composed of pressed lignocellulosic fibers with resin and presence of heat, concordant and discordant response to milling with diferetntes surfaces presents results. The objective of this study was to analyze the milling results in consistent direction and discordant through the MDF surface analysis with the average roughness parameter (Ra), given in units of micrometer (μm) The MDF panels were milled tangentially on concordant and discordant direction with six repetitions in each direction. The tests were carried out with four cutting speed in the forward speed of 2 m/min and 1 mm machining depths. The results of surface roughness in the cutting speeds in concordant direction are larger by 50% than in the discordant direction.
