Abstract

Portable machine tools are designed to reduce costs and resources necessary to perform dedicated tasks, such as milling of large components like wind turbine hubs. Such machines however lack in performance (e.g. stiffness, accuracy, thermal stability) with respect to conventional machine tools and may require compensation strategies to guarantee adequate accuracy. An offline compensation methodology, involving tool trajectory modification, based on the calculation of tool center point displacements from prediction of cutting forces and static stiffness characterization was implemented on a portable machine tool. The offline compensation was validated through a posteriori comparison with the nominal cutting conditions.
