Machining of tree discs to evaluate the annual growth rings with turn-milling Part 1
Pages: 5 - 10
The analysis of the pattern of annual growth rings is done by a lot of different disciplines: Phytology, wood biology, climatology, pollution control, geography, ecology, archaeology, architecture, science of forestry etc. But the machining of
cross-grained wood is one of the most difficult grinding tasks in woodworking. Up to now, such tree discs are prepared with a special machine, which cuts the surface with a sharp blade. This solution is very expensive, because for every test specimen a new blade is required. Furthermore it is just possible to prepare a small stripe instead of the whole disc. With the machining process of turn-milling it is possible to finish such tree discs in an adequate quality and in a short cutting time. In part 1 the milling strategy and the test equipment are shown. Part 2 will follow with the experiment parameters and the results.
