The determination of ploughing force and its influence on material properties in metal cutting

“…The resulting non-zero intercept is recognized as the ploughing force [14][15][16][17]. This method has been questioned by several researchers [18][19][20][21] as the tool-chip contact length, the strain, the strain rate, and the temperature were not accounted for. Inspired by Colwell's work [22], the zero-feed method [8,10] was proposed to trace the force versus time after steady-state cutting, but before the tool disengages with the workpiece.…”
