Cutting Forcess 71 Valery Marinov, Manufacturing Technology 5.3 CUTTING FORCES Introduction Cutting is a process of extensive stresses and plastic deformations. The high compressive and frictional contact stresses on the tool face result in a substantial cutting force F. Knowledge of the cutting forces is essential for the following reasons: v proper design of the cutting tools v proper design of the ±xtures used to hold the workpiece and cutting tool v calculation of the machine tool power v selection of the cutting conditions to avoid an excessive distortion of the workpiece Total cutting force F and reaction force F` in orthogonal cutting workpiece chip cut tool F F` Cutting force components In orthogonal cutting, the total cutting force F is conveniently resolved into two components in the horizontal and vertical direction, which can be directly measured using a force measuring device called a dynamometer. If the force and force components are plotted at the tool point instead of at their actual points of application along the shear plane and tool face, we obtain a convenient and compact diagram. Total cutting force F is
