Due to the technological advances and the constant search for materials with sustainable bias, the research and optimization of the processes related to the wood have become obligatory for the industry. MDP and MDF panels are widely used in furniture and handicrafts, appearing as an alternative technology to in natura wood. However, these materials need to go through machining processes, such as milling, until the final product is reached. The objective of this work is the comparative analysis between the answers of these two types of panels with respect to the process of frontal milling, using a carbide tool coated with TiAlN. Two cutting speeds (50 m / min and 100 m / min) and three feed rates per tooth (0.0416 mm / tooth, 0.0333 mm / tooth and 0.0250 mm / tooth) were used. The values of power consumed, vibration, sound emission, temperature, roughness and tool wear for each panel were measured. The analysis was performed based on graphs of main effects, interaction graphs and columns. The MDF panel presented lower values of roughness, noise emission, shear temperature, power consumed and tool wear than the MDP. Regarding vibration, the behavior of both materials was similar. It is concluded from this study that the MDF panel presents better machinability than the MDP panel for the speed parameters used
