Analysis of surface roughness of chemically impregnated Scots pine processed using frame-sawing machine

The objective of this work was to evaluate the effect impregnation process pine wood (Pinus sylvestris L.) on roughness parameters surface processed a frame sawing. samples were dried and impregnated using commercial procedure by local company. touch method with use measuring stylus (pin) employed determine considering parameters, namely, arithmetical mean value (Ra), total height profile (Rt), maximum (Rz) root-mean-square (Rq). All measured values analysed normalised raw density in order eliminate differences moisture content tested non-impregnated pine. Generally, no feed per tooth observed for fz1 = 0.11 mm fz2 0.22 parameters. Only parameter Rq significant observed. all both feeds tooth.
