Cutting forces in micro-end-milling processes
In the micro-milling process, a dramatic alteration of the cutting geometry can be induced by the cutting edge radius size effect. The deformation pattern of removed material in the micro-milling process is different compared to the macro-milling process, because the chip thickness is comparable in size to the edge radius of the micro-end-mill.
