Modelling of peripheral wood milling power using design of experiment approach

For efficient production planning, it is necessary to know the power consumption of a particular woodworking operation in advance. In the past, many power measurement tests have been carried out based on a large number of different combinations of technological parameters. However, in this paper, the effects of technological parameters and wood properties on the power magnitude of peripheral milling are analysed using experimental design methods, where the effects of the different factors can be tested with a much smaller number of combinations. Therefore, a central composite experimental design was used to plan the experiments. Three different tree species with different densities were milled with three different numbers of cutting knives and three depths of cut at constant feeding speed and rotational velocity. For each milling combination, the power was measured continuously and then the average power was calculated. Based on the measurements, a suitable model was determined that allowed the magnitude of the cutting power to be determined for each combination of technological parameters and wood species tested. The model proved to be suitable, as the deviations between the measured and modelled power values are minimal.
