Based on the research of the standard twist drill geometry parameters, the cutting part of the structure of the geometric parameters are expressed as a fuction of radius, the chisel edge and the main cutting edge geometric parameters of the mathematical model are established. Drilling force is one of the most important parameters in the process of drilling, it directly affects the size of the drilling quality, but the geometry of a drill make the drilling process complicated. Under certain spindle speed and feed rate, apply MATLAB software simulation to drilling force model, achieve the prediction of the dynamic of drilling force and torque of the forecast. Keywords-Twist drill; geometrical parameter; Mechanistic model; MATLAB; Prediction.
