INFLUENCE OF DIFFERENT PRODUCTION PROCESSES ON THE SURFACE ROUGHNESS OF OAK WOOD SAMPLES

The paper presents research on differences in roughness and the impact of parameters during different kind of processing surface of oak samples. Oak wood samples were planed in the radial direction. Planing machine was Weinig Powermat 600, and tool had four blades. It was planed at feed speed of 10, 15, 20, 25 and 30 m / min. Depth the planing grip was 1.00 mm, the chest angle of the tool blade was bio γ = 15 °, at 8000 ° / min. The diameter of the cutting blade was Φ = 125 mm. Another machining process was performed on a Viet Opera contact sanding machine in combination heads with pre-planing knives and roller with sanding belt. Roughness surface area was measured by the length of processing using electro mechanical profile meter Mitutoyo SJ-500. Oak samples had lowest roughness planed at the lowest feed speed of 10 m / min, the largest, samples that are planed at a feed speed of 30 m / min. Comparing roughness obtained during sanding and planing, it was determined that the surface roughness obtained on a sanding machine approximately corresponds to the roughness obtained by planing at a feed speed of 25m / min.
