Machining scale: Workpiece grain size and surface integrity in micro end milling

This chapter presents the need of adapting the workpiece grain size (GS) and specifying properly the cutting parameters when milling metallic materials with crystallographic structure at distinct scales mainly at micromilling. The effects of fine and coarse GS as well as milling scale and main cutting parameters on workpiece surface integrity are described and explained, such as burr formation, size effect, specific cutting energy, chip formation mechanisms, surface and subsurface microhardness, workpiece finishing and microstructure strain near machined surface.
