This article presents the research results showing wood surface roughness changing when milling with variable cutting path of milling tool, feed and cutting speed. The tests performed with the wood samples of birch and pine. The specimens were milled along the fiber in the experimental wood cutting stand at two different cutting and two feed speeds. The roughness parameter Rz of the processed specimens was measured in five sectors using the contact stylus surface roughness measuring instrument. The roughness was measured in each sector along and across the fiber and received measurement results were processed by Gaussian digital filter. The statistical analysis ranked machining surface roughness parameters by diminishing significance as feed speed, tool nose cutting path and peripheral cutting speed.
Keywords: wood milling, surface roughness, birch wood, pine wood
