Comparison of Technical and Economic Parameters of Cutting of Solid Wood Panels with Numerically-Controlled and Traditional Woodworking Machines
Pages : 1447-1451
The technology of wood mechanical processing has undergone positive changes, especially during the last two decades, achieving a rapid development through the application of advanced technologies. Numerically-controlled technology (CNC) has significantly improved technical and economic parameters, which has led to increased competitiveness of those companies that have installed this technology. The focus of this paper lies in the study of technical and economic parameters in cutting solid wood plates, used for the production of window frames, with CNC panel saw machines and with traditional saw-blade machines. The same cutting tool is used, cutting disc and pre-cutting disc, with the same geometry of the saw-blades cutting teeth for both machines. The study takes into account the cutting time of the constructive parts of the window frame, measured with the software of a CNC machine, and through a chronometer at the saw-disc machine. On the other side the costs of work force required for the operation are calculated. The results of the measurements and calculations reveal a clear advantage of the CNC saw-disc machines over the traditional saw-disc machines, in terms of operations times, enabling an increase in productivity and quality of the processing.
