Forestry has long been in a rather favourable position in offering a valuable raw material source in high demand. However, with rapidly changing end-user demands and cost competitiveness within the forest and wood chain as a whole, the industry is needing to adapt. Explaining entrepreneurial action as part of a chain of comprehensive value-added processes leads to a new perception of forest production and wood processing. This book applies the main concepts of modern managerial science to the world of forestry and is the perfect book for students studying forestry and wood processing, as well as entrepreneurs and managers within the sector. Topics are covered from an entrepreneurial perspective and include perspectives from accounting, finance, economics, supply chain management, marketing and strategy.

Im Rahmen dieses Buches wird ein Programm zur vollautomatischen 3D-FEM-Berechnung von Spiralbohrern realisiert. Dies enthalt auch die Modellerstellung. Ziel ist die Berechnung von verschiedenen Bohrergeometrien zur Optimierung von Vollhartmetall-Spiralbohrern. Dabei wird aus einem 2D-Querschnitt eines Bohrers sowie der Angabe verschiedener Parameter wie Lange, Verdrillung, etc. ein 3D-Modell erstellt und mittels FEM-Berechnung Zielgrossen ermittelt. Diese sind z.B. die Torsionsfestigkeit oder die Biegesteifigkeit. Das Programm ist vollstandig aus MATLAB heraus aufrufbar. Es werden die Programme OPENFEM als FEM-Programm, sowie GMSH als Mesher verwendet. Beide sind quelloffen und kostenlos verfugbar. Die Implementierung wird anhand von Parametervariationen auf Plausibilitat getestet und durch Vergleichsberechnungen mit einem validierten FEM-Modell in ANSYS-FEM verifiziert. Ziel ist es, die Verwendbarkeit von quelloffener Software im professionellen Bereich zu veranschaulichen und Anregungen zu geben, diese kostengunstige Alternative zu kommerziellen Produkten starker zu nutzen
