The presented research concerns the use of a laser profilometer to measure the surface roughness of green Douglas fir heartwood veneers during the peeling process. It investigates the effect of various process parameters on the surface quality. Three experiments were carried out with a single variable factor for each experiment: log centration, soaking temperature and cutting speed. Moreover, the origin of the surface roughness of Douglas fir green veneers was investigated. The study shows that laser profilometer seems to be a useful equipment in online measurement of surface roughness of green veneers. Based on the experiment results it was stated that surface roughness of Douglas fir veneers is characterized by large differentiation depending on the location on the veneer. The performed analysis shows that the surface roughness of Douglas fir green veneer could be improved when using relatively high cutting speed, not too high steaming temperature and logs with a centered core. The presented study shows that the laser profilometer can be effectively applied to the measurement and evaluation of green veneers during the peeling process and that there is still an area to develop this methodology.

用激光轮廓仪测量花旗松绿色饰面的表面粗糙度

提出的研究涉及在剥皮过程中使用激光轮廓仪测量绿色道格拉斯冷杉心材单板的表面粗糙度。它研究了各种工艺参数对表面质量的影响。进行了三个实验，每个实验有一个可变因素：对数中心，均热温度和切削速度。此外，还研究了花旗松绿色单板表面粗糙度的成因。研究表明，激光轮廓仪似乎是在线测量绿色单板表面粗糙度的有用设备。根据实验结果，可以得出道格拉斯冷杉贴面的表面粗糙度具有很大的差异，这取决于贴面的位置。进行的分析表明，使用相对较高的切割速度，不太高的蒸煮温度和中心居中的圆木可以提高花旗松绿色单板的表面粗糙度。提出的研究表明，激光轮廓仪可以有效地应用于去皮过程中生胶薄板的测量和评估，并且仍然存在开发此方法的领域。
