Aim
The compensation of disturbances in the generation of regular surface topographies (knife strokes, planing steps) during peripheral milling of wood (planing, fillets), which is currently only achievable to a limited extent or only with great effort, is to be made possible within the framework of the research project by using active elements (actuators) for motion correction on the milling tool. In addition to achieving the ideal (theoretical) blade stroke geometry, a reduction or compensation of the blade strokes also appears possible. Geometry, path and position errors of the tool determined by sensors should enable trajectory control or control by micro-adjustment processes through the peripheral placement of piezoelectric actuators (e.g. on the drive spindle bearing close to the tool or on the spindle sleeve). Appropriate control and regulation concepts play a very important role here.
By achieving the project goals, it will be possible to improve or stabilize the surface quality of machined workpieces in user-side machining processes (milling, planing) on wood and wood-based materials and to reduce the production effort and production time by avoiding multiple and additional process steps such as grinding in the shaping machining processes on wood and wood-based materials.
This makes it possible to increase competitiveness through more stable and better product quality and to speed up production for the large number of SME users in Germany (planing mills, window construction, furniture construction, timber construction, etc.) in the woodworking and wood processing industry. However, companies in the sector-specific mechanical and plant engineering industry, including its corresponding system and component suppliers, are also among the beneficiaries. In this respect, the targeted research results also have great economic significance in this area.
