Improving the facade element surface processing of MDF case furniture

A lot of enterprises engaged in the production of MDF case furniture face the problem of milled plate surface quality. It ensures the production of facing paper and synthetic film or finishing liquid paints and varnishes to improve the facade element surface processing quality of MDF case furniture. The experiments to study the roughness of MDF plates milled surface have been carried out, depending on the feed rate and tool rotation frequency. The work has been carried out using hard-face end mill tools manufactured in accordance with the patent for the utility model (Russian Federation), which enables to improve the quality of machined surfaces by performing finishing milling in one pass and increasing equipment productivity. The determination of the roughness parameter has been carried out in accordance with the requirements of 15612 State Standard. As a result of experimental processing, the dependences of milled surface roughness on the factors under study in the form of regression equations have been obtained. The mathematical dependencies are the results of this work. It enables to set regime parameters for profile milling of MDF surface plates to obtain the required roughness. The optimal milling mode has been determined improving surface finish facade element quality of MDF case furniture.
