In this paper, studies of incipient chip formation when cutting annealed 70/30 brass under orthogonal conditions are presented. Cutting forces were recorded and changes in deformation occurring in the workpiece were investigated for slow velocity transient cuts involving different rake angles. The deformation was observed by means of micro-hardness plots and recrystallization photomicrographs. Stresses on the apparent tool-work contact area were calculated.
