Cutting force is the resistance force that the cutting edge receives during cutting. It is measured by the principal component, the feed force, and the 3-component force of thrust force .
Thrust resistance is a cutting force mainly used in drills, and is the force of resistance applied in the opposite direction to the direction of travel of the tool. It is sometimes used as a cutting force for taps.
A cutting force is generated perpendicular to the cutting edge surface of a drill, etc., and the thrust resistance receives the cutting force in the axial direction, and the rotational force receives it in the radial direction.
