High aspect ratio manufacturing in the micro dimensional range by the micro milling process represents some difficulties for diverse applications such as micro moulds, micro channels, micro gears, miniaturized surgical instruments, etc. This study investigates the thin wall machining with different machining approaches and applies 3D finite element modelling (FEM) for the minimum machinable wall thickness to improve the experimental machining and enhance the quality of the machined features. The high stress distribution during machining the thin features are presented and the smallest machined wall is investigated. Finally, the FEM prediction resultsare compared against the experimental tests.
