Influence of Minimum Quantity Lubrication on Tool Temperature and Wear in Wood Machining

The machining of wood and wood-based materials is becoming increasingly interesting in view of the progressive application of this class of materials in various industrial sectors, such as furniture, doors, windows, interior fittings and sustainable construction in the building sector. In order to promote the establishment and further development of wood construction in particular, it is necessary to research and develop approaches to solutions in the field of machinery, processes and tools in order to optimize manufacturing processes. In the industrial environment, wood and wood-based materials are usually processed dry. Unfavorable process parameters often lead to thermal problems, which can have a negative impact on the machining qualities. In contrast to dry cutting, there is hardly any scientific knowledge available for wood machining using minimum quantity lubrication (MQL). In this paper, the results on the influence of the use of MQL when sawing solid wood are discussed. Within the framework of experimental investigations, various process parameters were varied and the effects on tool temperature and tool wear were analyzed.
