Abstract:

In accordance with the aims a complex study of wood processing by milling was done conduced. All experiments (were made by the process of) involved counterdirectional plane milling on multispindle milling machines commonly used in woodworking industry. The chips removal cutting tests were carried out on fir according to a previously established tests plan. In addition to milling direction, temperature and wood moisture, also geometric and time parameters as well as electric power were also determined by measurements in the course of testing. The feed speed was varied (in the cours of testing). The procedure was repeated for 4 different milling depths. The relation between cutting energy on the one hand, and feed speed and average chip thickness on the other, was studied by a linear regression model. At the same feed rate (vf=20 m/min) the following relation was established for milling depth and cutting power 3:4:6:8=1: 1,3:2,3:3,5. By using regression analysis with exponential function we have established that specific cutting resistance and specific cutting energy depend on the strong link between the interdependence established by correlation.
