Micro-milling is widely used in various crucial fields with the ability of machining micro- and meso-scaled functional structures on various materials efficiently. However, the micro-milling force model is not comprehensively developed yet when tool feature sizes continually decrease to under 200 µm in a low-stiffness system.

Micro-milling — also known as fine milling and surface planing — is one of the best ways to restore the age-old, oxidized asphalt pavements. It is considered a better alternative to standard milling, as it produces finer results. While traditional milling leaves the surfaces rough, micro-milling provides a smoother and plainer surface to ...

Frequency response function (FRF) at the micro-milling tool point reflects dynamic behavior of the whole micro-milling machine–spindle–tool system. However, the tool point FRF of micro-milling cannot be obtained directly through the hammering test. To solve the problem, the authors get the FRF of the spindle system based on the rotating ...

Micro milling is a competitive process to manufacture small parts and to structure surfaces in high quality with low set-up costs. However, the micro milling process poses many challenges and basic mechanisms are still to be researched. In addition, process-machine interactions are much more pronounced in micro than in macro machining.
