Calculation of cutting force during drilling of drilling machine

A source of cutting force,cutting force and its decomposition,cutting power to study cutting force,to further clarify the cutting mechanism,to calculate power consumption,to the design of tools,machine tools,fixtures,to develop reasonable cutting amount,optimize tool geometry parameters Etc.,all have very important meanings.
In metal cutting,the force required to cut the workpiece into the workpiece and deform the material to be the chip is called the cutting force.The cutting force comes from three aspects:Overcoming the resistance of the material to be elastically deformed;Overcoming the resistance of the material to plastic deformation;Overcoming the friction of the chip against the rake face and the surface of the tool facing the transition surface and the machined surface Friction between.Source of Cutting Force The sum of the above forces forms the resultant force Fr(national standard F)acting on the tool.

For practical applications,Fr can be decomposed into three components of Fx(national standard Ff),Fy(national standard Fp)and Fz(national standard Fc).During turning:Fz-cutting force or tangential force.It cuts off the transition surface and is perpendicular to the base surface.
