The technology of final wood processing has undergone during the last two decades positive changes, achieving a rapid development through the application of advanced technologies as the numeric-controlled machines (CNC). The focus of this paper lies in the comparison of technical and economic parameters in drilling operations, with a three-dimensional CNC mill-drill machine and with a traditional, horizontal-vertical tenoner drilling machine. The materials used in the study are particleboard panels for the production of a window-case. The study compares (i) the cutting time of the constructive parts of the window-case measured by the software of the CNC machine, and through a chronometer at the tenoner drilling machine and (ii) the cost of labor force engaged. The comparison of technical and economic parameters measured/calculated reveals clear advantages of the three-dimensional CNC machine over the traditional one. These advantages consist in operations time savings, higher quality of processing, lower internal transportation times, lower costs of processed parts and automatic optimization of material.
