<p>The invention relates to a process, a tool and a machine for mechanically profiling wood prisms with a view to cutting aesthetic veneers with stay log-type rotary machines while eliminating the time for cutting useless veneers, the invention being applicable in the field of wood industry. According to the invention, the process consists in machining wood prisms by cherrying to convert the zones () of the wood prisms () into chips thereby making a profiled surface identical to the cutting path of the machine. The tool, as claimed by the invention, is a milling cutter with detachable cutting blades having curved cutting edges which is dimensioned to correspond to the kinematic and dynamic parameters imposed by the wood milling regimes. The machine, as claimed, is mounted on its own metal framework which frames the bedframe of the machine for planning and straightening wood prisms, the working position being set according to the shape and size of each prism, so that, depending on the dimensions of the cross section of the wood prism (), the milling cutter ()can be positioned in the vertical plane by means of a table () actuated by the gearmotor (), the table () being also rotatable in the vertical plane by some degrees so that it allows a surface identical to the cutting path of the veneer cutting machine to be obtained, the electric motor () and the V-shaped transmission belts () being dimensioned depending on the kinematic and dynamic parameters required for accurate machining.</p> |
