Sažetak
The article presents the results of a research on the energy efficiency of woodworking machines and surface roughness of machined surfaces after machining on the machines in the secondary processing plant of the company Spačva d.d., Vinkovci. As a part of the project, the aim of this part of the research was quantification of energy efficiency and surface roughness of every machine in the secondary processing plant that is used for production of the elements that are used in later processing stages for door production. The electrical power and electrical energy requirements were measured on every machine during representative working conditions and surface roughness was measured in laboratory conditions on the representative samples of workpieces from the production. From the measured electrical power the average specific cutting energy and average specific energy needed for unit production was calculated. For roughness assessment the Ra, Rq and Rz parameters were measured and for waviness the Wa, Wq and Wz parameters were measured. The results show that most of the machines that were inspected have specific cutting energy that is in line with good practices. Some of the machines are overloaded with intermittent high spikes of electrical current that cause the high temperature of main electric motor and some machines underutilise main electric motor drive. The results of surface roughness and waviness show great deviation of the results (on one sample and between samples) and poor surface quality. The results indicate that the main driver of surface roughness in this case is not the kinematics of cutting (tooth marks on the machined surface), but other factors such as tool geometry, lateral cutting forces, errors in workpiece feed.
