CUTTING FORCE OF END CUTTING TOOL MILLING MACHINING

For the cutting force measurement, a Kistler Quartz 3-Component Dynamometer was used. Depending on the different depth of cut where value for spindle speed and feed rate are constant, the cutting forces were evaluated for the AISI 1020 Mild Steel. Within certain cutting parameters range, the increasing depth of cut increased the cutting forces. Beside that, cutting force requirement for 2
