Effects of Horizontal Roller-Bar Openings on Quality of Rotary-Cut Southern Pine and Yellow-Poplar Veneer
Effects of various horizontal roller-bar openings were evaluated during rotary-cutting of small disks of clear wood. Knife bevel, 21?, and knife angle were held constant. The optimum horizontal roller-bar opening […]

Effects of panel density, panel temperature, and cutter sharpness during edge machining on the roughness of the surface and profiled areas of medium density fiberboard
The success of direct painting and thin laminating of profiled medium density fiberboard (MDF) is dependent upon the smoothness of surfaces and profiled areas. Many variables can affect surface smoothness […]
