By use of a load cell, a computer and a fast scanning device we have examined the cutting-forces on the tool in a milling machine. Several experiments have been elaborated with different rotation and feeding speeds. The aim is to study, in detail, how wood chips are produced. By a better understanding of this process it must be possible to manufacture wooden details for furniture and other products with minimal errors and, hence, there will be reduced need for sanding and other expensive extra treatment in order to achieve an acceptable result of the finished surface. The load cell was used to register the forces in three directions. These registrations, however, were not easy to interpret because of the vibrations which were introduced in the experimental setup when milling started. A computerized filter therefore had to be used in order to extract only those registrations which were of interest. We found that the cutting forces in beech varied from approximately 40 up to 86 N/cm in the work-piece feed direction, i.e. in the Y-direction, and from about 14 to 51 N/cm in the X-direction, i.e. in the normal to the cut surface. A larger average chip thickness resulted in larger forces but we could not find a clear relationship which, in full, explained our result. © Springer-Verlag 2005.
